1.4 Screen Calibration

Having a properly calibrated monitor is a critical factor when viewing images. Ensure that the digital viewing conditions are as accurate as possible. A quality monitor and calibration tool should help guarantee that displayed images on a screen are precisely rendered. Once a monitor has been calibrated; the color and brightness controls should be locked to prevent inadvertent changes.

Hardware-based monitor calibrators are now available at reasonable prices. The process is simple, quick and enables images to be viewed with confidence. Many higher level monitors have internal calibration software that works with professional calibration devices for ultimate accuracy.

2.0 The 645DF + Camera and Credo Digital Back System

The Mamiya Leaf Camera system is created to provide as much flexibility and openness as possible. Follow the instructions below to setup and use your Mamiya Leaf camera system.

2.1 Charging the Batteries for the Credo Digital Back

Charge the batteries as soon you unpack the camera system.

Although only one battery can be used in the Leaf Credo back at a time, it is recommended to charge both batteries fully before you start.

Always keep a battery in the Leaf Credo back even when shooting tethered to a computer via a FireWire or USB connection. Go to page 80 for more details about charging the battery while tethered to a computer.

The battery charger can adapt to voltages within a range of 110 to 250 volts. It comes with an international set of power adapters. Select the appropriate one that fits your outlet and slide it in from the top to mount it in place securely.

Connect the unit to the outlet and charge the batteries (approximately 2.5 to 3 hours).

Purchasing Extra Batteries

The Leaf Credo back comes with two batteries (2900 mAh). You can purchase additional batteries or use Canon BP 915 batteries.

Some third party batteries may not fit into the digital back's battery compartment due to differences in the tolerances. Do not try to force a battery into the compartment. When pressing the battery release button it should slide in without being hindered.

There is little power remaining. Have new batteries on hand. Camera still operates.

The batteries are sufficiently charged.

There is very little power remaining. Camera does not operate. Set the shutter release mode selector lever to L (to turn the power off) and replace the batteries with new ones.
When the batteries are emptied for power, batt flashes on the main LCD and the viewfinder's LCD when the shutter release button is pressed.

2.2 Batteries for Camera

Set the shutter release mode selector lever to L (to turn the power off).

Use the Mamiya Li-Ion rechargeable battery pack, six AA alkaline or rechargeable AA batteries. (If you are not using your Leaf Credo on a Mamiya 645DF+, skip to page 24.)

Li-Ion, NiCd or NiMH batteries should only be used in the camera body if CF04 is set to the specific type of rechargeable battery used. If using the Li-Ion battery pack, ensure that the custom function has been set to 2 (Li-Ion rechargeable battery).

Inserting Li-Ion Battery Pack

1. Turn the battery pack lock lever counter clockwise.
2. Slide the Li-Ion battery pack into the camera's battery compartment.
3. Lock the battery by turning the lever clockwise. Make sure it is firmly attached.

Inserting AA Batteries

1. Lift the battery case lock lever, turn it counter clockwise and pull out the battery holder.
2. Insert fresh batteries with the + and - ends as shown in the illustration.
3. Return the battery holder to its case and lock it by turning the lever clockwise. Make sure it is firmly attached.

Note: Ensure that the batteries are placed with the correct polarity.

Checking the Battery Power

Set the Drive dial lever to S to turn the power on.

Check the battery condition in the lower left corner of the top LCD screen.

Always use six new batteries of the same type when replacing batteries. Do not mix different types of batteries or use old batteries with new ones. The camera can't function without a power source.

Never throw batteries in the garbage. When a battery does not work, ensure the battery is disposed of in an appropriate manner.

For the purpose of the descriptions and explanations provided in these instructions, it is assumed that the camera's power is on.

2.3 Sleep Mode

The camera's power is switched on when the shutter release mode selector is set to S, C or M.UP. In order to prevent the camera's batteries from discharging, sleep mode is automatically entered if no operations are performed for a specific period of time while the power is ON (with exposure metering status maintained).

In sleep mode, operating the shutter button or a function setting button restores power ON status.

In sleep mode, the external LCD screens are not active, only the marks shown in the figure are displayed. (These marks appear in program AE mode.)

1. Battery life of the originally supplied batteries is dependent on storage conditions.
2. Blots and fingerprints on the battery terminals may cause a loose connection and corrosion. Wipe them off before loading the batteries.
3. It is advised to carry spare batteries in remote or foreign locations.
4. Battery performance decreases in low temperatures. Keep them warm when in cold climates or locations. An external battery case (PE401) is available as an optional accessory.
5. Store the batteries in a cool and dry place, away from direct sunlight.
6. Remove the batteries from the camera body if you plan on not using the camera for a long time.
7. Replace the batteries with new ones as soon as they are exhausted. Liquid leakage from the battery can damage the camera.
8. Read the warnings on the batteries for their handling.

2.4 Attach and Remove a Lens

1. Remove the front body cap in the same way that you would remove a lens; push the lens release button A backward and then turn the front body cap or the lens itself counter clockwise and lift out.
2. Align the white alignment dot of the lens B (on the shiny flange) with the camera's white dot C. Mount the lens and rotate it clockwise until it clicks into place.
3. To remove the front lens cap, squeeze the shiny sections together and lift out (see image far left). To remove rear lens cap turn it counterclockwise.

Remove a Lens

Slide the lens release button A back, rotate the lens counter clockwise until it stops, and lift it off. After removing the lens from the camera body, protect both ends by attaching the caps.

Note: Oil, dust, fingerprints or water on the electronic contacts could result in malfunction or corrosion. Wipe such impurities off with a clean piece of cloth. Do not tap the distance ring or other rotating parts when attaching the lens. When installing a lens, do not press the lens release button.

Attach a Leaf Shutter Lens

Leaf shutter lenses are equipped with an internal shutter. Leaf shutter lenses are capable of high shutter speeds 1/800 sec or 1/1600 on Leaf Credo series backs with flash synchronization, which is particularly useful for fill-in flash photography in bright ambient shooting conditions.

When a leaf shutter lens is attached and the leaf shutter is used, the letters LS appear in the main LCD screen.

2.5 Adjusting the Strap

Put the neck strap through the mounts and secure it to the buckle as illustrated. After attaching the strap, pull it and ensure it does not loosen at the buckle.

2.6 Attaching the Leaf Credo Back

The Leaf Credo back is fully integrated with the camera body and functions as a part of the whole camera system.

Ensure that the Mamiya 645DF ^+ camera mirror is up and the shutter is open when there isn't a digital back attached.

When attaching the Leaf Credo back to the camera body the shutter closes and the mirror comes down.

First remove the cover. Next, ensure that the bottom part of the Leaf Credo back is placed correctly in the lower locking mechanism on the back of the camera body before the upper locking mechanism A+B is pressed together. Failure to do this can cause an error with the camera body where the shutter continuously opens and closes. If this occurs, remove the Leaf Credo back. Make sure the camera body is powered, press the digital back release button ② while mounting the digital back, lock the mounted back by sliding the digital back lock ① toward the camera.

Be aware that the shutter should be in the correct starting position (shutter open). If this is not the case, attach and remove the Leaf Credo back again to make sure that the camera body gets in the correct starting position.

Remove the Leaf Credo back by sliding the digital back lock ①, pushing in the digital back release button ②, and by gently pulling away the top of the back first. Be careful with the contacts and protective glass on the back. Your Leaf Credo back should always be protected by its plate when it is not attached to the camera.

2.10 The Buttons on the Back

The Credo is equipped with four soft buttons. The buttons change function to match the menu shown on the screen.

2.11 LED Lights

Credo series digital backs feature two LEDs. One is located next to the on/off button and the other is inside the CF card compartment.

The red LED indicator located next to the CF card slot (under the cover) is assigned to indicate CF card activity only. Do not remove a CF card from the card slot when this red LED is on. Removing a CF card when the red LED is on can damage the formatting of the card, and images or data might be lost or corrupted.

2.12 Setting Date and Time

Date and time parameters are set and controlled via the Leaf Credo back's Menu system.

If the Leaf Credo back has been without power for a long period of time, it automatically asks you to set the time and date on the next occasion it is powered up.

Tap the screen and scroll through the numbers to attain the appropriate date and time.

The time and date is applied to the EXIF data in all files captured with the Leaf Credo back.

2.13 Setting Diopter

Look through the viewfinder and make sure that the focus frame (rectangle with circle) is in sharp focus. If it is not, turn the diopter adjustment dial in the “-” direction if you are nearsighted or in the “+” direction if you are farsighted. If this is not sufficient you may require an optional diopter correction lens. Check the table for possible diopters.

Point the camera at a bright, plain object such as a white wall when making this adjustment.

Notice:

If there is dirt or dust on the lens surface, remove it with a blower or sweep it off gently with a lens brush

If there are fingerprints or dirt on the lens surface, wipe them off with a piece of clean, soft gauze

Using solvents could discolor the correction lens frame

3.0 Basic Functions

ISO and White Balance

The Leaf Credo back's Home screen enables quick access to the ISO and white balance (WB) settings by tapping the screen directly. White Balance and ISO settings can also be controlled from Capture One if you are working tethered.

3.1 Setting ISO

The default ISO setting is 50 for all Leaf Credo series models. Remember that the higher the ISO setting, the higher the degree of image noise. The camera system together with Capture One software deliver a powerful noise reduction performance although it is possible to still see some noise at the higher sensitivity settings.

Tap the ISO icon on the Leaf Credo back's Home screen. You are presented with the back's ISO spectrum. Tap the screen to select the desired setting. A green frame surrounds the selected ISO and you are returned to the Home screen.

Find out more on ISO operation on page 57.

3.2 Setting White Balance

The default WB setting is Auto. The camera calculates a white balance based on the information in the image. Auto WB is appropriate for most applications where the subject color and lighting are consistent.

Tap the WB icon on the Home screen. You are presented with the back's white balance settings. Scroll left or right and tap the icon to select the desired setting. A green frame surrounds the selected WB and you are returned to the Home screen.

Find out more on White Balance operation on page 58.

Focus Mode Focusing

S Single focus mode	Half-press the shutter release button to focus. When the focus mark lights, the focus is fixed and the shutter can be released.
C Continuous focus mode	The camera keeps focusing continuously while the shutter release button is half-pressed. The shutter can be released regardless of whether or not the focus mark is lit.
M Manual focus mode	Focus manually.

3.3 Setting the Shutter Release, Focus, Exposure and Metering modes

1. Set the Shutter Release mode selector lever to S (single-frame advance mode).
   There are two shutter release (drive) modes: S (single frame advance mode) and C (continuous advance mode). When set to L the power is turned off.
2. Set the Focus mode selector lever to S (Single focus mode).
   There are three Focus modes: S (Single focus mode), C (Continuous focus mode) and M (Manual focus mode). See page 29 for more information.
3. Set the exposure mode dial to P (Program auto exposure).

There are four exposure modes:

P (Program Auto Exposure)

Av (Aperture Priority AE)

Tv (Shutter Priority AE)

M (Manual)

Note: Av stands for Aperture Value but is referred to as Aperture Priority AE. Tv stands for Time Value but is referred to as Shutter Priority AE.

Notice:

When a polarizing filter is used, ensure that a circular polarizing filter (C-PL) is used. The correct exposure cannot be obtained with a normal (linear) polarizing filter (PL).

P: Program AE — The aperture and shutter speed are determined automatically for the optimum exposure, according to the ambient light conditions. This auto mode is best suited for general photography or for novice photographers, as it leaves the user free to concentrate on framing and capturing the subject.

Av: Aperture priority AE — Set the desired aperture and the camera selects the correct shutter speed. Use this mode to control depth of field.

Tv: Shutter priority AE — Set the desired shutter speed and the camera selects the correct aperture. Use this mode to stop motion.

M: Manual mode — Set this mode to use special combinations of the aperture and shutter speed.

1. Exposure metering mode is automatically set to average/spot exposure metering before exposure metering is performed. There are three exposure metering modes: In the A mode the average brightness in the entire frame is measured with emphasis on the center of the frame. The brightness at a specific spot in the center of the frame is metered in the S mode. The A-S mode automatically switches between these two modes depending on the contrasts in the picture.

Average/spot auto exposure metering	Exposure metering is performed after automatically selecting average/spot exposure metering. Depending on the subject conditions, center-weighted average/spot exposure metering is selected automatically, and the correct exposure is measured. Spot exposure metering is automatically selected when the brightness of the spot exposure metering range becomes darker than the brightness of the entire screen. If there is very little difference between the spot exposure metering value and center-weighted average exposure metering value, the correct exposure level is obtained as the intermediate value.
Center-weighted average/spot exposure metering	The average brightness of the entire screen is measured, emphasizing the center of the screen.
Center spot exposure metering	The brightness of an area equivalent to 7.6% at screen center is measured, and the exposure is determined. The circle at screen center serves as a general guideline. This mode is suited to measuring subjects with strong contrasts or measuring only screen portions.

3.5 Focus Modes

To use the Auto Focus function, both the camera body and the lens have to be set to their respective Auto Focus modes. Auto Focus does not function when either the camera body or the lens are set to manual focus.

To activate Auto Focus (AF), first select AF on the focusing selector ring on the lens. Next, adjust the Focus Mode Selector Lever to either S (single) or C (continuously) Auto focusing on the camera. The Focus selection ring on the lens can help you to rapidly switch between AF and M, without having to change your grip of the camera.

The shutter release button has a two-step action. When pressed lightly it stops at a certain point. In this manual, this position is called the half-press position. When you half-press this button, the camera functions are activated. When the shutter button is pressed further down, the shutter is released. This position is called the full-press position.

1. Aim the camera so that the subject is within the focus frame.
2. Half-press the shutter release button, and focus is adjusted automatically in AF mode. As default, you can now re-compose your image without losing the original focus setting, by moving the camera and keeping the shutter release button half-pressed. When the focus mark lights up, the subject is in focus.
3. When the focus mark lights up, press the shutter release button further down to release the shutter. (The focus mark is an illuminated dot (indicated as this • symbol) at the bottom of the viewfinder display. See the focus mark in the illustration circled in red).

Out of Focus Marks ▶

When the picture is not focused the shutter cannot be released when in single focus mode. Either press the shutter release button again to adjust the focus or move the camera to change the position of the focus frame. Lenses without the focus mode selector ring are automatically set to AF if the camera is set to Auto Focus. Do not touch the focus ring as you may cause internal damage to the camera Auto Focus motor.

Lenses with the Focus Mode Selector

The focus modes can be switched between automatic and manual with the selector on the lens when the focus mode selector lever on the camera body is set to S or C.

Single Focus Mode (S)

This mode uses the focus-priority mechanism. The shutter can be released when the focus mark • in the viewfinder is illuminated. This mode is suited for still subjects. Focus is locked when the focus mark • is illuminated in the viewfinder's LCD.

The shutter cannot be released if the subject is not in focus (if the focus mark • does not illuminate).

To take another photo with a different composition, take your finger off the shutter release button then re-press the shutter release button again.

Continuous Focus Mode (C)

In this mode shutter release has priority to focusing. The shutter can be released regardless of whether the focus mark • in the viewfinder's display is illuminated. Focus is adjusted continuously while the shutter release button is half-pressed. This mode is suited for moving subjects.

Focus is not locked even if the focus mark is lit.

The shutter can be released even if the focus mark is not lit.

Manual Focus Mode (M)

To attain full manual control of the focus function you can change to manual focus mode in two ways.

1. All lenses: Turn the focus mode selector lever to M (Manual focus mode).
2. Manual Focus operation for telephoto and zoom lenses: All newer Mamiya, Phase One and Schneider-Kreuznach lenses can be switched from Auto Focus to Manual Focus by using the AF ring or slider fitted on the lens.

For lenses with AF slider, slide the focusing ring on the lens backward until it clicks. When this is done, the Auto Focus inscription on the lens barrel is covered and the lens can then be focused manually. For lenses with an AF ring, simply rotate the AF ring to the MF position to select manual focus.

Manual Focusing using the Focus Mark (Focus confirmation method)

Half-press the shutter release button and turn the lens focusing ring to focus on the subject. The focus mark is illuminated in the viewfinder's LCD to signal that a picture is in focus.

If is lit in the viewfinder's LCD, the camera is focused on a point behind the object.
If is lit, the camera is focused on a point in front of the object.

• Use the focus mark when taking photos in manual focus mode or when using the M645 manual lens.
• If you adjust focus using the focus mark with an M645 lens, make sure to open the aperture. You can use this function with the lens set to f/5.6 or higher.

When Auto Focus Fails

The auto focus function requires contrast in the subject. Auto focusing may fail to achieve focus with certain subjects described below. In such cases, either switch to the manual focus mode (and focus manually) or focus on a more contrast appropriate object at the same distance as the object you want to photograph, lock the focus using the focus lock button on the front of the camera body, then take a picture.

• Low-contrast subject (blue skies, white walls and other objects)
• Two or more objects overlapping at different distances within the focus frame (animals in cages, etc.)
• Subjects with continuous repeated patterns (building exteriors, blinds, etc.)
  • Extremely backlit reflective subjects (car bodies, water surfaces, etc.)
• Or when the subject is far smaller than the focus frame

3.7 Using Focus Lock and Infrared Focusing

Use the focus lock when your intended focus point is not within the focus frame. In such cases where a subject is not located in the center of a frame, use the focus lock function to lock the focus before releasing the shutter.

1. Set the focus mode selector lever to S or C.

Put the subject in the focus frame and half press the shutter release button.

2. Lock the Focus.

When the focus mark • in the viewfinder LCD is lit, press the AF lock button on the front of the camera to lock the focus.

3. Adjust the Composition.

With the shutter release button half-pressed, slide the camera to achieve the desired composition, and release the shutter. When the focus mode is set at S (Single focus mode) and the focus mark • is lit, hold the shutter release button halfway down to lock the focus.

AF Assist Infrared Light

Autofocus can fail when a subject is dark or very low-key. On these occasions, a red lamp may be activated on the front of the camera when the shutter release button is half-pressed to assist the camera's auto focus function. The AF assist infrared light is emitted only when the focus mode is set to S (Single focus mode).

3.8 Drive Dial

Single-Frame Mode

One photograph is taken each time the shutter release button is pressed.

Set the shutter release mode selector to S.

Continuous Mode

Photographs are exposed as long as the shutter release button is pressed.

Set the shutter release mode selector lever to C. Photographs are taken continuously at a rate depending on the buffer speed of the digital back mounted on the camera.

Mirror Up Mode

When the shutter button is pressed, the mirror moves up, and when the shutter button is pressed again, the shutter is tripped and a picture is taken.

Self-Timer Mode

In this mode, the shutter is released 10 seconds after the shutter release button is pressed.

Activate the Self-timer by pressing the 📋 button. Next, rotate the front dial so that On is displayed in the camera's LCD and press the shutter release.

When the shutter release is pressed, the Self-timer lamp blinks continuously for seven seconds, followed by three seconds of rapid blinking until the camera releases the shutter.

Notice:

If a correct exposure cannot be obtained, the shutter speed and aperture value blink. In such cases, the pictures can be taken, but they may be too bright or too dark.

If the shutter speed and aperture values blink on the main LCD and in the viewfinder display when the program line is shifted, the proper exposure cannot be achieved.

Select a different program mode.

When the Program line is shifted, the aperture value changes along with the shutter speed to maintain the proper exposure.

Increment of the aperture and shutter speed can be set at either 1/3- or 1/2-stop.

3.9 Exposure Modes

(P) Program AE

The aperture and shutter speed are determined automatically for the optimum exposure, according to the ambient light conditions. This auto mode is best suited for general photography or for novice photographers, as it leaves the user free to concentrate on framing and capturing the subject.

Notice:

This camera's sync contact is an X contact.

Using flashes designed exclusively for other camera manufacturers in the hot shoe may damage the camera's internal mechanisms. In this situation, use an off-camera flash bracket and connect a sync cord to the camera's sync terminal.

When using flashes with a flash duration of 1/500 sec or longer, set the shutter speed to 1/30 sec or less.

3.10 Flash Photography

The Mamiya 645DF+ is equipped with a vertical-travel focal plane metal shutter and it is also compatible with leaf shutter lenses.

The focal plane shutter provides higher shutter speeds than that of leaf (central) shutter lenses. Focal plane shutters allow you to shoot fast enough to freeze moving subject matter. Leaf shutter lenses allow faster shutter synchronization to flash, making it ideal for freezing subject movement when using strobe lighting.

The focal plane shutter method allows for shutter speeds of up to 1/4000 sec. When shooting at higher speeds e.g. 1/500 sec the two shutter blades are moving in parallel creating a small slit allowing a small fraction of light to reach the sensor area of the digital back. When using this type of shutter it is not possible to achieve flash synchronization greater than 1/125 sec.

A leaf shutter makes it possible to achieve faster shutter and flash sync speeds. A Leaf Credo series back can sync at maximum shutter speed of 1/1600 second.

1. A grip type flashgun or a strobe (with electric contacts other than X contact) can be operated with the Mamiya 645DF+ by connecting a sync cord into the camera's sync terminal. See the note on the left side of this page about flash units designed exclusively for other camera makes.
2. Turn the exposure mode setting dial to X (1/125 sec) or M (Manual). When M (Manual) is selected, turn the front dial and set the shutter speed to 1/125 sec or slower.
3. Turn the rear dial to set the aperture, and then press the shutter button to take a picture.

In addition to its standard flash sync system, the Mamiya 645DF^+ features TTL (through the lens), off the film/sensor (OTF) and electronic flash exposure metering.

Mamiya 645DF+ features Through the Lens (TTL), Off the Film/Sensor (OTF) and electronic flash exposure metering. A flash sensor located inside the camera body reads the flash light reflected off the surface of the CCD at the moment of exposure. The sensor is connected via the Mamiya 645DF+'s dedicated hot shoe to a shoe or handle-mount style Metz flash unit via the Metz SCA 3952 TTL Adapter. Maximum flash speed is 1/125 second when the focal plane shutter is used, making daytime synchronization possible.

The ISO of the flash is automatically set through the TTL connection from the digital back; any adjustment to this is instantly recognized after the setting is locked and the shutter release is half-pressed.

To utilize the TTL flash feature with all TTL-operable Metz flash units, a Metz SCA 3952 module is required. See the chart for capability and/or additional adapters that may be necessary.

The resulting flash exposure automation determines correct flash exposure and automatically adjusts the output of the flash. It also automatically corrects for exposure compensation normally required when using filters, close-up bellows or extension tubes.

1. Mount the SCA 3952 adapter onto the Metz flash, insert fully into the camera's hot shoe, and then tighten with the locking knob A.
2. Set the exposure mode, and then check the shutter speed and aperture.

TTL flash

With TTL flash photography, the reflection of the flash is metered and the intensity of the flash is adjusted automatically, which can mean TTL flash photography may not be suitable for all shooting conditions. In the cases described below, we recommend that you use a flash meter to check the intensity of the flash or use a manual flash setting.

Example:

1. When the size of the subject you want to light with the flash is relatively small within the picture
2. When the background behind the subject is extremely bright or when there is a strongly reflective object in the background
3. When the background behind the subject is extremely dark (outdoors at night, etc.)
4. For flash photography with a narrow sensitivity latitude

4.2 General Hardware Setup

Powering up the Leaf Credo back

After a Leaf Credo back is connected to a camera body, insert a battery, USB 3.0 or FireWire 800 cable and it automatically turns on. The back is switched on/off by pressing the power button located at the top of the Leaf Credo back.

ISO Settings

The Credo 80 back has a default ISO range from ISO 35-800. The Credo 60 and Credo 40 have a default ISO range from ISO 50-800. An ISO rating can be selected from the menu system (when untethered) or in the Capture Tool in Capture One Pro software (when tethered).

Shutter Latency

The default setting is Normal Latency, which should remain unchanged under all 'normal' shooting scenarios. Only change the setting to Zero Latency if you work on technical cameras, large format cameras or certain manual cameras in special situations.

Double Exposure Protection

It is not possible to accidentally double expose an image by capturing one shot quickly after another when a Leaf Credo back is used on cameras such as the Mamiya 645DF+/AF/AFDIII, Phase One 645DF+, Hasselblad 555 ELD (DIG mode), Hasselblad H or Contax 645. The electronic communication with the body ensures that the Leaf Credo back is ready before allowing release of the next shot. However, users of other camera bodies that do not use the electronic interface from the Credo have to wait for the ready beep signal before releasing the next shot.

4.3 Indicator Light

Credo series digital backs feature an indicator LED located beside the on/off button. When the Leaf Credo back is in sleep mode, the green LED is illuminated. The LED goes out as soon as the back is activated. In general, if the LED is not illuminated and the back and camera are on, the camera is ready.

4.4 CF Card LED

There is an additional red LED indicator located next to the CF card slot (under the cover). It indicates CF card activity. Do not remove a CF card from the card slot when this red LED is on. Removing a CF card while the red LED is on can damage the formatting of the card, and images or data might be lost or corrupted.

4.5 Tethered and Untethered Operations

Untethered: A Leaf Credo series back can be operated as a fully portable battery powered unit. Image files are shot and transferred to a CompactFlash card which is inserted in the CF card slot on the left side of the camera back.

Tethered: Remember to always keep a battery in the Leaf Credo back even when shooting tethered to a computer via a FireWire connection. When operating tethered, image files can be shot to a CompactFlash card or transferred directly to the assigned capture folder in the Capture One application on the computer hard disk. (See page 80 for more details about charging the battery when tethered to a computer).

Driver Set-up

Find out more on installation and activation of software on page 8 and 10 of this User Guide. There is no specific program set-up. Check the Capture One User Guide for recommended hardware. Firmware announcements are available on our website, and in our newsletters.

Connecting

The maximum length of a compatible FireWire cable is 4.5 meters. Longer cables might require a third party power solution or a FireWire hub. Leaf Credo series backs match the FireWire 800 standard.

Plug the FireWire 800 cable into the Credo unit and into the back of your Mac or Windows PC. (It is not recommended to use a FireWire port on the front of a computer as it can be less stable). Capture One automatically recognizes the Leaf Credo back and settings. Read more on shooting tethered in the Capture One software manual.

Note: Leaf Credo backs are compatible with FireWire 400. Order a Mamiya Leaf FireWire 800 to 400 cable 4.5 m. Part no: 50300164.

Tethered Operations Continued

The display on a Leaf Credo series back can be either be turned off while shooting tethered or set to display the images while they are shot, just as if shooting untethered. It is also possible to enlarge a section of an image on the Credo screen to help check focus of the current and upcoming captures.

A Leaf Credo back defaults to its untethered mode when the FireWire 800 or USB 3.0 cable is removed in its Auto Storage setting. Captured image files are stored on a CompactFlash card, and the unit's battery provides power.

The Leaf Credo back can be forced to shoot to either CompactFlash, or via a USB 3.0 or FireWire 800 cable to a computer. Find out more on the Storage Mode on page 81.

Online Support

For more information on shooting tethered with Capture One, consult the online user guide available in the Capture One Help menu.

4.6 CompactFlash Card Usage

It is important to follow a few simple guidelines to help avoid loss of data when working with CompactFlash cards, card readers and digital cameras. Mamiya Leaf recommends that you test-drive all new CompactFlash cards with your Leaf Credo back. By performing an initial test to verify that the capture files are stored properly on the card and can be accessed on a computer you avoid unpleasant surprises on location or when you return from a job. CompactFlash cards are manufactured by other suppliers and Mamiya Leaf cannot guarantee that the cards are not defective.

Inserting and Ejecting on the Leaf Credo Back

The CompactFlash card is inserted in the slot located under the cover on the left-hand side of the Leaf Credo back.

Insert the CompactFlash card with the brand label facing the display end of the digital back as shown in the image.

The cover can be closed when the CompactFlash card is fully inserted.

To eject the card push the small button above the card once, and an ejecting pin comes out. Pushing this pin all the way back in ejects the card.

Microdrives are not recommended for use with Leaf Credo backs.

4.7 Secure Storage System (3S)

You can always be sure that your data is safe when working with memory cards in a Leaf Credo back. The Mamiya Leaf Secure Storage System (3S) provides the industry's safest memory card handling. The 3S technology automatically checks your card's file structure every time it is inserted into the Leaf Credo back. If the Check Disk function finds an error, it prevents usage of the card until it is corrected or the card is formatted.

How does 3S work?

A complete disk check for a valid file structure is performed as soon as a card is inserted into the Leaf Credo back.

Lower gigabyte capacity cards load quicker than high capacity versions.

It is not recommended to turn off the Check Disk function. If you want to turn it off go to Home > Settings > Check Disk.

Disk Check Summary

3S technology is a safe storage system integrated into the Leaf Credo back and is much more rugged than anything else seen in the industry. DSLR cameras do not have this level of storage security.

Benefits include:

• No need to format a card on a computer.
• Damaged or incorrectly formatted cards are detected immediately. Leaf Credo backs also have the ability to reformat and correct these cards.
• Ejecting a card while it is writing a session does not necessarily damage the file structure of the entire CompactFlash card. Only the image being written and the images in the buffer can be damaged.

4.8 Formatting your Memory Card

Most CompactFlash cards are preformatted and ready for use in the Leaf Credo backs. However, Mamiya Leaf recommends that all cards be formatted in the Leaf Credo back to ensure their optimum performance.

Memory card formatting is done in either FAT 16 or FAT 32 depending on card size. (Leaf Credo backs support CompactFlash cards formatted in both FAT 16 and FAT 32.)

Using CompactFlash Cards in a Card Reader

A card is mounted as a removable drive on a computer after it has been inserted into the card reader and connected to a Mac or PC. Windows and Mac OS X have the required drivers for the CF card reader. For information on how to import files to Capture One, consult the Capture One online user guide available under Capture One Help in the Help Menu.

Warning!

Ejecting a card or removing the battery while the Leaf Credo back is still writing (when the red LED is on) causes images that are not written to the card to be permanently lost or damaged. Do not bend or flex your CompactFlash card. Keep the card away from moisture, grit and sand. Use a CompactFlash card case as a storage container when not in use.

5.0 Navigating the Credo User Interface and Menu System

Home Screen

The Credo Home screen is the first view that you see as soon as the back is switched on. This is the back's default screen and the starting point in which to navigate the menu system. Use the Home screen to configure the Leaf Credo back's setup, camera settings, ISO sensitivity and White Balance (WB) settings.

The selected ISO rating and White Balance setting are displayed on the Home screen

The bottom right of the Home screen features a Power Indicator icon that shows the remaining battery capacity or an electrical icon if the Credo is being used to shoot tethered via a USB 3.0 or FireWire 800 connection.

7.1.28 About System

This menu screen displays the camera and lens firmware being used. Remember to check the camera firmware number against the latest version. Go to www.mamiyaleaf.com/firmware.asp to get the latest firmware for the 645DF+ camera and Leaf Credo back.

7.2 Power Management

The Power Management menu option has three criteria to help preserve battery life and help keep operating temperatures low when working in hot conditions.

Display Off Time

Switch off the Credo's display screen after 5 seconds, 20 seconds, 1 minute or 5 minutes. The display can also be set to remain permanently on while the Credo is in operation with the Always On option.

Battery Charging

The Leaf Credo back has an integrated battery charger to ensure that the battery is charged when shooting tethered via a USB or FireWire connection. This function can be switched off or set to Slow or Fast. The Slow and Off settings should be chosen to preserve the battery life of a laptop when shooting tethered.

Note: The battery only charges via a USB or FireWire connection when the Leaf Credo back is switched on. Only after it has been switched on, does it continue to charge when it is turned off.

Auto Power Down

Auto Power Down determines the amount of time before the Leaf Credo back shuts down, when there is no activity. Choose 1 minute, 5 minutes, 30 minutes, 2 hours or deactivate this function by selecting Off.

Press the Power button to switch on and restart the Leaf Credo back after it has shut down.

7.3 Format Card

Select Format Card to erase all data on a memory card. Memory card formatting is done in either FAT 16 or FAT 32 depending on card size. (Leaf Credo backs support CompactFlash cards formatted in both FAT 16 and FAT 32).

7.4 Check Disk

A disk check is performed on every memory card that is inserted into the Leaf Credo back. Mamiya Leaf recommends leaving this feature turned on, to maximize data security on memory cards. This feature can be deactivated in this menu. Read more about the Mamiya Leaf Secure Storage System on page 52 of this User Guide.

7.5 Storage Mode

Storage Mode allows users to configure how a Leaf Credo back stores image captures. Auto is the default storage setting and it detects and automatically stores image files to a memory card if it has been inserted in the Leaf Credo back.

If the Leaf Credo back is being used in tethered mode, it stores image files directly to the computer via the connected FireWire 800 cable. The FireWire has priority if a card is in the Leaf Credo back at the same time as it is connected by FireWire to a computer.

Note: The Leaf Credo back can be forced to shoot to either CompactFlash or via a FireWire 800 cable to a computer by selecting CF or FireWire respectively. An Error Message appears on the Credo screen if the Leaf Credo back is not tethered to a computer and the Credo card slot is empty.

7.6 File Format

A Leaf Credo back can save files in two different Raw formats; IIQ L and IIQ S. IIQ stands for Intelligent Image Quality Raw. IIQ L is the default setting and it is a lossless capture format. IIQ S is a smaller file that is not a totally lossless format. An IIQ L file is approximately 1/3 the size of a processed TIFF. An IIQ S file is approximately 1/5 the size of a processed TIFF.

7.7 Camera Mode

There are two primary choices in the Camera Mode menu. Mamiya mount Leaf Credo backs have three choices. Select one of the following options:

Normal: The recommended default setting.

RZ67ProIID: This mode is designed to optimize the Leaf Credo back's operating performance with the Mamiya RZ67 Pro IID camera body.

7.8 Shutter Latency

The Credo's CCD is put to sleep to reduce power consumption when it is not in use. The Credo needs to wake up before shooting and the timing of this wake up signal is referred to as the Latency. The recommended setting is Normal Latency if the Credo is used with the Mamiya 645DF+. Only change to Zero Latency if you work on technical, large format cameras or certain manual cameras in special situations.

7.9 Image Orientation

The Image Orientation function sets and stores the orientation of all subsequently captured images. Select 0°, 80°, 180° or 270° to force the back to mark images as captured with that orientation. The Auto setting uses the back's built in orientation sensor to determine the orientation at the moment of capture. Changing this setting does not affect how captured images are displayed on the LCD.

7.10 Auto Preview Mode

The Auto Preview option can be switched On or Off. Select On to revert to a Browse mode when shooting. Select Off to remain on the same display.

7.11 Display

The Display menu option has an option for Brightness, Display Off Time and Ready Beep.

Brightness

Set the brightness of the preview LCD screen to suit ambient viewing conditions. The default setting is 80% but in bright outdoor illumination this can be increased up to 100%. Users may choose to lower the Brightness when working in low light environments, such as a photographic studio.

Altering the Brightness setting only affects the brightness of the screen. It does NOT affect the Exposure Warning, Histogram and the exposure of captures.

Display Off Time

Switch off the Credo's screen after 5 seconds, 20 seconds, 1 minute, 5 minutes. The display can also be set to remain permanently on while the Credo is in operation with the Always On option.

The Leaf Credo back emits a small audio beep after every capture is taken. This Ready Beep signals that a capture has been completed, and that the Leaf Credo back is ready for the next shot.

The Ready Beep can be set to either None, Single or Multi. The default setting is Single. Multi is ideal for use in noisy surroundings. None deactivates the audio Ready Beep.

Notice:
You cannot take photos in AE modes when using an infrared back as the AE is based on visible light.

9.13 Infrared Photography

Infrared Photography is complicated when using digital backs, as the digital back is adjusted to match the viewable light perfectly.

Use a dedicated digital back for infrared photography. The Leaf Credo back needs to be adjusted to work properly for infrared photography. DO NOT TRY THIS AT HOME!

- All corrections in this area must be done by Mamiya Leaf to ensure precision. If you remove the protective glass or make other physical adjustments on the back the warranty is immediately voided.

If you are considering Infrared Photography, contact your local Mamiya Leaf dealer for technical advice and pricing.

Infrared light has a slightly different area of sharpness compared to visible light, so when the distance is set on the lens, you should always manually correct sharpness to be in front of the red dot.

Do not use your camera's light meter when photographing infrared, as the light meter is designed to measure visible light.

9.16 Custom Dial Modes C1, C2 or C3

Mode dial options C1, C2 and C3 can be used to store preferred settings.

These settings can be changed instantly to suit the photographer's needs. Users can change the settings on the camera body or via a Leaf Credo back.

Programmable settings are exposure mode, P (Program AE), Av (Aperture priority AE), Tv (Shutter speed priority AE), X (Sync mode), M (Manual mode), focus area and spot metering.

Programming the Custom Dial Modes C1, C2 or C3 via the camera body

1. Go to the setting you wish to assign to C1, C2 or C3.
2. After arriving at the setting you wish to assign, hold the SET button down while turning the mode dial to C1, C2 or C3. When you release the SET button, the chosen setting is programmed to your selection of C1, C2 or C3.

C1, C2 or C3 modes can be changed while photographing. However after taking a photo in a mode other than the modes selected in C1, C2 or C3, when you turn the dial back to a C mode setting the change is not saved.

9.17 Lenses and Multi-Mount

When it comes to lenses, Mamiya Leaf provides the widest range of possibilities to ensure photographers get the most creative freedom from their Mamiya camera.

This chapter looks at some possible lens systems. However, it is worth noting that there are even more applicable lenses available than presented in the upcoming pages. Users can find more information from Mamiya Leaf dealers on items such as mount-adapters, for example the Phase One Multi-Mount.

Note: Errors or damage caused by third party products are not covered by the warranty. Use new products with caution.

9.18 Function of the Phase One Lens Adapter

To mount the Phase One Multi-Mount on the Mamiya 645DF+, match the white Lens Mount Alignment Mark on the Multi-Mount with the Lens Mount Alignment Mark on the camera and turn slowly clockwise. NEVER use force to mount the ring. When the Phase One Multi-Mount is mounted, you can mount Carl Zeiss/Hasselblad V and Hasselblad 200 series lenses on the camera.

Notice:

Since the focusing screen's surfaces are soft and easily damaged, handle them carefully.

Never touch the surface with bare fingers. Should dust settle on it, merely blow away by using a blower.

If the focusing screen needs cleaning, send it to the nearest authorized Phase One service center.

Do not attempt to clean the surface of the focusing screen, as it is very delicate.

Do not touch and damage the mirror in any way.

10.0 Maintenance

The Mamiya 645DF+ generally needs very little maintenance. But this is a professional tool and should be treated with care and caution. Always do test shots before a photographic session if the camera has not been used for a long period of time.

A frequently used product should be inspected periodically at the nearest official Mamiya Leaf repair center. Do NOT try to repair any camera, lens or back errors or malfunctions – consult your local dealer.

10.1 Changing the Focusing Screen

1. Remove the lens.
2. Pull the Focusing Screen Release lever A forward, as illustrated, with tweezers to ease the focusing screen down.
3. Remove the focusing screen from the focusing screen frame by grasping the tab on the edge of the screen with tweezers as illustrated.
4. When installing the screen, pinch the tab of the screen with tweezers, and place the screen on the screen frame.
5. Push the screen frame up using the tweezers until hearing a clicking sound. The screen is now properly installed. Never press down on other parts as this affects the focus function.

Notice:

Make sure to re-install the empty battery case into the body.

The empty battery cassette must be inserted into the body.

The batteries may generate heat if the external battery case is connected to the body while the batteries are loaded on the body.

10.2 Battery Socket

Never leave batteries in the socket if the camera or back is not going to be used for long periods of time.

Keep contacts clean and dry at all times.

External Battery Socket

Use an external battery case PE401 when using the camera in cold environments, where the battery capacity may drop.

1. Turn the shutter release mode selector lever to the L position (power off).
2. Use a coin or similar object to turn and remove the external battery socket cap.
3. Remove the battery case from the camera body
4. Connect the external battery case to the body.
5. Connect the plug of the external battery case in which the batteries are installed, to the external battery socket.
6. Reinstall the original battery case, from which the batteries were removed, in the body. Turn the battery case lock to lock it in the body.

10.3 Tripod/Electronic Shutter Release Contact

Keep all contacts clean and dry at all time.

When using a tripod with 3/8 in screw (instead of 1/4 in screw), remove the small screw A from the tripod screw hole on the bottom of the body using a Phillips screwdriver, then use a coin to remove the tripod screw adapter bushing B.

The Electronic Shutter Release is found both on the camera body and on the back. When needed, it is recommended to use the shutter release on the back. Keep both contacts dry and clean.

10.5 Lens Maintenance

Never touch the inner optics of the lens with your fingers. Keep the inner optics perfectly clean with air, a lens brush or the dry cloth delivered with the lens.

Do not touch the contacts. Keep the contacts clean with either a dry cloth or by using a fiberglass brush. Do not use any other tools on the lens.

The lens is not waterproof. It should be immediately dried with a cloth if it becomes wet. If it is exposed to salt, moisten a cloth, wring it and carefully clean.

10.6 Back Maintenance

Cleaning the IR Filter

The Leaf Credo back must have the protection plate fitted when it is not attached to a camera. Dust may accumulate on the IR filter, which degrades the image quality if not removed. Follow the directions found at http://www.mamiyaleaf.com/cleaning.asp.

10.7 IR Filter on the CCD

The IR filter (Infrared reduction filter) is permanently mounted on top of the CCD. The filter may not be removed for several reasons:

• The focusing of the Leaf Credo back camera back can be altered.
• It is only possible to remount the filter without dust getting in between the filter and the CCD if you have access to special clean room facilities.
  • The Mamiya Leaf Product Warranty is terminated.

10.8 Mamiya 645DF ^+ Camera Body Specifications

• Open platform for maximum choice and compatibility
  • Durable, proven platform for secure operation

13.0 Open Platform – Freedom of Choice

Mamiya Leaf's Open Platform policy delivers maximum choice and compatibility with a wide range of different camera platforms.

This section covers the Leaf Credo back's compatibility with the Hasselblad V and H series, Mamiya RZ67 Pro IID, Phase One 645, Mamiya 645, Contax 645 and View Camera solutions.

Double Exposure Protection

It is not possible to accidentally double expose an image by capturing one shot quickly after another when a Leaf Credo back is used on cameras such as the Mamiya 645DF+/DF/AF, Phase One 645DF+/DF/AFDIII or Hasselblad 555 ELD (DIG mode). The electronic communication with the body ensures that the Leaf Credo back is ready before allowing release of the next shot. However, users of other camera bodies that do not use the electronic interface from the Credo must wait for the ready beep signal before releasing the next shot.

Viewfinder Masks

Cameras including the Mamiya RZ67 Pro IID and Hasselblad V-series need a viewfinder mask as the image area of these models is different to the image sensor size of the three Credo models.

13.1 More Details: Leaf Credo and Mamiya 645 Series Cameras

Power Management and Shutter Latency

The Credo CCD is put to sleep to reduce power consumption when it is not in use. The Credo needs to wake up before shooting and the timing of this wake up signal is referred to as the Shutter Latency.

The Leaf Credo and Mamiya 645DF ^+ camera body response time is independent of the shutter latency setting so it is therefore recommended to keep the latency on the Normal (default) setting, as this ensures a longer battery life.

Studio Flash Sync on the Camera Body

A flash sync lead should be connected to the camera body when using the Leaf Credo back on Mamiya 645DF+, DF, AF, Mamiya AFD or AFDII models.

Always use a flash cable and/or equipment that provides grounding for the flash.

Image Orientation

The CCD in the Leaf Credo back is positioned in a landscape orientation. However, the Leaf Credo back has an internal sensor that detects when it has been rotated. Thus, when the camera is rotated and an image is captured in portrait position the image appears correctly oriented on the LCD and in the Capture One application.

14.0 Leaf Credo back for Mamiya RZ67 PRO IID

The Leaf Credo backs are compatible with the Mamiya RZ67 PRO IID with the use of an adapter plate.

The Mamiya 645DF+ version of a Leaf Credo back can be used on a Mamiya RZ67 PRO IID with a Mamiya RZ67 PRO IID adapter plate. (Mamiya Leaf # 518-04228A)

14.1 Mounting Leaf Credo back on the Mamiya RZ67 PRO IID

1. Place the bottom of the Leaf Credo back in the locking mechanism.
2. Press the button at the top of the back with your thumb and lever the back into place.
3. Release the button to lock into position.

Note: It is important to ensure that the bottom part of the Leaf Credo back is attached correctly before the upper locking mechanism is pressed together.

Mounting the Leaf Credo back Vertically

The CCD in the Leaf Credo back is positioned in a landscape orientation. However, it is possible to mount the Leaf Credo back in an upright orientation to capture images in a portrait format without having to rotate the camera. The Leaf Credo back has an internal sensor that detects when it has been rotated so images appear correctly oriented on the LCD and in the Capture One application.

Mount the Leaf Credo back in the portrait position by lining up the adapter mount to the corresponding indentations on the left side of the back. Press the button and lever the back into place. Release the button to lock into position.

The image area of the Mamiya RZ67 Pro IID at 56 x 69.5 mm is larger than the size of the three Credo models' sensors so it is necessary to insert a viewfinder mask.

There are two different masks available for the Mamiya RZ67 Pro IID according to the specific Credo that is being used. (The Credo 80 and Credo 60 models' CCD is 53.9 x 40.4 mm while the Credo 40's CCD measures 43.9 x 32.9 mm).

Installing a Viewfinder Screen

1. Remove the viewfinder from the camera body according to the manufacturer's instructions.
2. Remove the focusing screen, and then replace it with the supplied focusing screen.
3. Reinstall the viewfinder on the camera body according to the manufacturer's instructions.

Note: Check the relevant Mamiya RZ67 Pro IID manual regarding how to dismount the viewfinder and remove the focus screen.

14.3 More Details: Mamiya RZ67 Pro IID

Mode Selector

The mode selector on the trigger button should be turned to the white dot when used with the Leaf Credo back. The selector should be set to the orange dot to avoid draining the small battery when the Leaf Credo back is attached to the body and not in use.

Warning: Even if the Leaf Credo back is turned off, the battery drains slowly if the orange dot is not selected.

Shutter Latency Setting Mamiya RZ67 PRO IID

Select the special Mamiya RZ67 PRO IID camera mode, which is available in the Camera mode menu to ensure that the correct latency setting is used.

Viewfinder Information

The viewfinder information bar is located below the image area within the viewfinder display. It displays the camera's exposure mode and values etc. It also includes a counter with the number of captures remaining on the storage media (see top bar circled left). '99' is the maximum number displayed. '99' continues to be displayed if there are more than that remaining on a CompactFlash card. An 'E' indicates that the storage media is full. Users must delete some captures or replace the CompactFlash card before continuing (see bottom bar circled left).

Double Exposure Protection

It is not possible to accidentally double expose an image by capturing one image quickly after another when a Leaf Credo back is used on a Hasselblad H1/H2.

Note: At the end of an exposure, image information has to be moved from the CCD to the processing system. During this short period of time the CCD must be protected from light exposure. The Leaf Credo back ensures that the CCD is safely cleared of information by disabling the Hasselblad camera's shutter release during this procedure.

Image Orientation

The CCD in the Leaf Credo back is positioned in a landscape orientation. However, the Leaf Credo back has an internal sensor that detects when it has been rotated. Thus, when the camera is rotated and an image is captured in portrait position the image appears correctly oriented on the LCD and in the Capture One application.

TTL flash

Using TTL flash with the Contax 645 camera and Leaf Credo back results in a two f-stop overexposure. When using TTL flash, the exposure compensation on the flash unit must be set to -2 f-stops.

This overexposure happens because the CCD element reflects light differently than film and this cannot be communicated to the Contax.

Image Orientation

The CCD in the Leaf Credo back is positioned in a landscape orientation. However, the Leaf Credo back has an internal sensor that detects when it has been rotated. Thus, when the camera is rotated and an image is captured in portrait position the image appears correctly oriented on the LCD and in the Capture One application.

17.4 Flash Lead Connection

A flash cable is always connected to the Contax 645 camera body.

18.1 Using the 2-shot Release

The Leaf Credo back can be used with mechanical shutters that can be fired twice within four seconds. The first release of the shutter activates the digital back; the second release is for the exposure. If the time limit of four seconds is exceeded, the camera gives a warning 'beep' followed by a 2-shot error warning that is displayed on the LCD screen.

There are several automatic or semi-automatic 2-shot solutions available from third party manufacturers for use with a mechanical shutter. Please ask your dealer for more information.

18.2 Using the 1-shot Release

The 1-shot release cable is created to simplify your studio workflow.

1. Connect the flash exit (circled left) to the shutter and plug the opposite end to the multi-pin port on the Leaf Credo back (via Part# 50300144 from multi-connector to mini jack female).
2. Connect a flash sync lead to the port on the Leaf Credo back.
3. Close the shutter if necessary.
4. Push the button (circled left) on the 1-shot release lead to 'wake up' the camera back and take the shot within a few seconds.

Note: It is not possible to control the exposure or trigger the shutter from Capture One when using a fully manual camera. Only limited EXIF data is recorded when shooting with manual cameras. The Leaf Credo back adds a calculated approximate shutter speed but the aperture value is not recorded.

18.3 Shutter Latency Settings for Technical Camera Adapters

Technical camera adapters for the Leaf Credo back can be used with both normal and zero shutter latency.

Select the Normal latency setting if the Leaf Credo back is used on a camera with a 2-shot release.

Please note: The Zero shutter latency setting increases the power consumption of the Leaf Credo back, as it is always prepared for exposure.
