Frequently Asked Questions - Mecablitz M360 METZ

Which cameras is the Metz Mecablitz M360 compatible with?

The M360 is available in versions for Canon (E-TTL II), Nikon (i-TTL), Sony (pre-flash TTL), Olympus/Panasonic/Leica (FourThirds/Micro FourThirds TTL), and Fujifilm (TTL). It cannot be used with other brands or converted between systems.

What batteries does the M360 use and how many flashes can I expect?

It uses 2 AA batteries (alkaline or NiMH rechargeable). With full output, you get approx. 130 flashes with alkaline batteries or approx. 160 with NiMH (2100 mAh). Recycling time is about 3-4 seconds.

How do I mount the flash on the camera?

Turn off both camera and flash. Loosen the knurled nut, slide the connection foot into the hot shoe, then tighten the nut. For Sony versions, remove the protective cap before mounting.

What is the Auto OFF function and how do I wake the flash?

The flash enters standby mode after about 2 minutes of inactivity to save power. To wake it, lightly press any button on the flash or half-press the camera shutter. The flash turns off completely after 1 hour.

Can I use the flash wirelessly or as a slave?

No, the Mecablitz M360 does not support wireless or slave operation. It must be mounted on the camera hot shoe.

How do I perform bounce flash?

Tilt the swivel reflector vertically (e.g., 60°, 75°, or 90°) to bounce light off the ceiling or wall. Ensure the reflector is angled enough to avoid direct light on the subject. You can also use the integrated reflector card for catchlights.

Why is the AF assist light not working?

Make sure the flash is ready (green LED) and the camera is in Single AF or One Shot mode. Some cameras only support their internal AF light, or only the central AF sensor triggers the flash's AF assist. If using a peripheral AF point, switch to center.

How do I update the firmware?

Connect the flash to a computer via the micro USB port and visit the Metz website (www.metz-mecatech.de) for firmware updates and instructions.

What does the multifunctional LED indicate?

Green flashing: charging. Constant green: flash ready. Slow red blinking: standby mode. No light: flash off or asleep.

How do I clean and maintain the flash?

Wipe with a soft, dry cloth. Do not use cleaning agents. For the contacts, use a cloth moistened with pure alcohol. If not used for long periods, remove batteries and perform flash capacitor forming every 3 months (switch on for 10 minutes).

It is impossible to describe all camera types and their individual dedicated flash functions within the scope of these instructions. Therefore, please refer to the flash mode description in your case which's operating instructions to find functions are supported and which ones have to be set manually on the camera. Using lenses not equipped with a CPU (i.e., lenses without auto focus mode), results in certain functional limitation.

4 Preparing the flash unit for use

4.1 Power supply

Suitable batteries/rechargeable batteries

The flash unit can be operated with any of the following batteries:

• 2 nickel-metal-hydride batteries 1.2V, type IEC HR6 (size AA)
• 2 alkaline-manganese dry cell batteries 1.5V, type IEC LR6 (size AA). Maintenance-free power source for moderate power requirements.

Please only use the power sources given above. If other power sources are used, there is a risk of damaging the flash unit.

If your flash unit is not going to be used for an extended period of time, remove the batteries.

Replacing the batteries

The rechargeable batteries/batteries are empty or flat when the flash delay exceeds 60 seconds (interval between triggering a full output flash and when the flash readiness indicator is relit).

• Switch off the flash unit by pressing the button ⑨ ON / OFF until all LED lights are off.
• Remove the flash device from the camera and slide the battery compartment lid ⑦ downwards.
• Insert the new batteries and slide the battery compartment lid ⑦ back into place to lock it.

Please ensure the batteries/rechargeable batteries are inserted correctly by checking against the symbols in the battery compartment. Incorrect insertion can terminally damage the unit. Risk of explosion in event of improper use of batteries. Always replace all batteries with the same high-quality brand batteries of the same capacity. Used batteries and rechargeable batteries should not be disposed of with domestic waste. Do your bit for the environment and dispose of used batteries/rechargeable batteries at designated collections points.

4.2 Mounting the flash unit

Mounting the flash unit on the camera

Turn off the camera and flash before mounting or removing.

• Turn the knurled nut ⑤ towards the flash unit housing as far as it will go. The locking pin in the connection foot ⑥ is now fully retracted into the case.
• Slide the flash unit connection foot ⑥ completely into the camera accessory shoe.
• Turn the knurled nut ⑤ towards the camera housing as far as it will go, clamping the flash unit in place. If the camera does not have a locking hole, the spring-loaded locking pin retracts into the connection foot case so as not to damage the surface.

In the case of the mecablitz M360 / Sony, the contacts in its multi-interface connection foot are covered by a protective cap and thus protected. Before mounting in the camera's hot shoe, this protective cap has to be removed from the connection foot of the flash unit.

Removing the flash unit from the camera

Turn off the camera and flash before mounting or removing.

- Turn the knurled nut ⑤ towards the flash unit housing as far as it will go.

- Remove the flash unit from the camera's accessory shoe

With the mecablitz M360 / Sony, the protective cap for the contacts in the multi-interface connection foot has to be pushed back onto the connection foot to protect the contacts for transport and storage.

4.3 Switching the flash unit ON and OFF

• Switch on the flash unit by pressing the button ON / OFF ⑨.
  The multifunctional LED ⑪ blinks green and signals the process of charging the main flash capacitor.
  As soon as the main flash capacitor is fully charged the multifunctional LED ⑪ lights constantly green and signals that the flash unit is ready for the next shoot.
  Running in the energy saving standby mode the multifunctional LED ⑪ blinks slowly red. See also 5.1 Multifunctional LED signals, please.

- Switch off the flash unit by pressing the button ON / OFF ⑨ until all LED lights are off.

In the event that the flash unit will not be required for a longer period of time, we recommend switching the unit off by pressing the button ON / OFF ⑨ and removing the power supply (batteries, rechargeable batteries).

4.4 Automatic unit shut-off / Auto OFF

The flash unit is configured so that approx. 2 minutes after -

• switching on,
• triggering the flash,
  • lightly depressing the camera shutter release,
  • switching off the camera flash metering system...

...it switches to standby mode (Auto OFF) in order to both save energy and avoid any unintentional draining of the power source.

The test button / multifunctional display LED ⑪ flashes slowly red during standby mode.

The flash unit shuts off completely approx. 1 hour after last use.

4.5 Wake-Up Function

To use the wake up function, simply press any button for approx. 1 second or lightly depress the camera shutter.

The flash unit should always be turned off using the main switch if it is not going to be used for an extended period.

5 Test button

The Test button ⑪ offers you the possibility to fire a short test flash. Additionally the various multifunctional LED signals of it will inform you for the current status mode of the flash unit.

5.1 Multifunctional LED signals

Depending on the current operating status of the flash unit the multifunctional LED ⑪ will signal the working status of the flash unit:

5.1.1 Flash readiness signal

After switching ON the flash unit the multifunctional LED ⑪ will blink green until the flash capacitor is fully charged and the flash unit is ready for the next shoot.

The Test button ⑪ illumination will light up constantly green when the flash capacitor is loaded and shows that the flash is ready to fire.

This means that the flash can be used for the next shot. Flash readiness is relayed to the camera where a corresponding message appears in the viewfinder (so far the camera offers such a function; see camera's manual, please).

If the photo is taken before the flash readiness message appears in the camera viewfinder, the flash unit will not be triggered and your photo maybe be incorrectly lit in the event that the camera has already activated flash sync control shutter speed.

5.1.2 Standby signal

On a prolonged operation break for more than approximately 2 minutes the flash unit will enable the energy saving standby operation mode. While the standby operation mode the multifunctional LED ⑪ blinks slowly red.

5.2 Fire a testing flash

As soon as the multifunctional LED ⑪ lights up constantly green and signals flash readiness. To fire a testing flash can be released by pressing the Test button ⑪ in order to check the basic function of flash unit.

6 TTL flash modes

6.1 Digital TTL flash modes

Depending on the camera system and the version of flash unit there are various digital TTL flash control systems available:

Canon E-TTL II ; Nikon i-TTL ; Sony pre-flash TTL ; Olympus/ Panasonic FourThirds- and Micro-Four-Thirds TTL ; Fujifilm TTL.

In the digital TTL flash modes you can easily achieve very good results in flash photography. The flash unit uses TTL measuring pre-flash technology:

When shooting, one or two TTL pre-flashes will be fired first by the flash unit.

The light of the TTL pre-flashes does not contribute to the exposure of the image.

The flashlight of the TTL pre-flashes reflected by the subject is taken care of by a sensor in the camera. It measures reflected light through the lens (TTL).

In TTL modes, excellent flash exposure is straight-forward. In TTL mode, flash metering is taken care of by a sensor in the camera. It measures reflected light through the lens (TTL).

The benefit of TTL flash modes is that all factors which could influence the exposure (filters, changes to aperture and focal length for zoom objectives, extensions for close-ups etc.) are automatically taken into account through flash light adjustment.

6.2 Automatic TTL fill-in flash mode

For most camera types, automatic TTL fill-in flash is activated in programmed auto mode "P" and variable or subject programs in daylight conditions (see camera operating instructions). With fill-in flash you can remove annoying shadows, and in back-lit shots a balanced exposure can be achieved between subject and background. A computer-controlled measuring system on the camera ensures appropriate combinations of shutter speed, working aperture and flash output.

Ensure that the backlight source is not shining directly into the lens. This will interfere with the camera's TTL metering.

There is no adjustment or display for automatic TTL fill-in flash on the flash unit in this instance.

6.3 Manual flash exposure correction in TTL flash mode

This function has to be configured on the camera, see camera operating instructions.

The automatic flash in most cameras is set to 25% reflectance (average reflectance of flash subject).

A dark background which absorbs a lot of light or a light background which is heavily reflective (e.g. backlit shots) can cause the subject to be over or underexposed.

To compensate for the above effect, the flash output can be adjusted manually with the correction value of the shot.

The correction value is based on the contrast between the subject and the background.

Hint:

A dark subject in front of a light background = positive correction value.

A light subject in front of a dark background = negative correction value.

Exposure correction through alteration of the lens aperture is not possible, as the camera's automatic exposure views the altered aperture as the normal working one.

Manual flash exposure correction in TTL flash modes can only take place if thecamera supports this feature (see camera's manual).

Don't forget to delete the TTL exposure correction on the camera after the shot.

Highly reflective objects in the intended shot can disturb the camera's automatic exposure. This results in underexposure. Remove reflective objects or set a positive correction value.

6.4 TTL Flash exposure memory FE

Several Nikon and Canon cameras have a flash exposure memory (FV memory). This is supported by the flash unit in the Nikon i-TTL or in the Canon E-TTL II flash modes.

It can be used to define and store the exposure level for the subsequent shot before the shot is actually taken.

This can be useful when, for example, the flash exposure has to be adjusted to specific details that may not be necessarily be identical with the main subject.

The function is activated on the camera, in some instances as an individual function. The subject detail to which the flash exposure is to be adjusted is sighted and brought into focus with the AF sensor/metering window in the camera.

Pressing the camera's AE-L/ AF-L button (Nikon) or FE button (Canon - the description may vary from camera to camera; see camera operating manual) causes the flash unit to fire a test flash. The stored metering value, for example "EL" or "FEL", is then displayed in the camera viewfinder.

The camera uses the reflected light of the test flash to determine the light output required for the subsequent exposure.

The actual main subject can then be bAFsertsiort/metersing with the camera's

window. When the shutter release is pressed, the picture will be exposed with the previously defined light output of the flash unit!

In Canon cameras the flash exposure memory FE is not supported during the green fully-automatic programme, the Vari programme and the subject programmes!
For more detailed information on adjustments and handling, refer to the camera's operating instructions!

7 Swivel reflector

Flash unit's motor zoom swivel reflector ③ can illuminate lens focal lengths from 24 mm and up (135 format).

By using the integrated wide-angle diffuser ② this value is extended to 14 mm.

7.1 Auto zoom

The zoom position of the swivel reflector is automatically adjusted to the lens focal length when the flash unit is used with a camera that transmits the data related to the lens focal length.

Automatic adjustment does not occur when the wide-angle diffuser is extended.

7.2 Wide-angle diffuser

With the integrated wide-angle diffuser, focal lengths from 14 mm can be exposed (135 format).

Flip the wide-angle diffuser out of the swivel reflector as far as it goes and let go. It will fold down automatically.

The main reflector will be guided to the required wide-angle position automatically.

Diagram of a folding or lifting mechanism with arrows indicating direction (no text or symbols)

Automatic adjustment of the motor zoom main reflector does not occur when the wide-angle diffuser is in use.

To set the wide-angle diffuser to 90° flip it up and slide it in completely.

7.3 Mecabounce diffuser

The mecabounce diffuser (included in the box) can be attached to the front of the motor zoom main reflector.

With this diffuser, soft lighting can be achieved in a very simple manner. It gives your pictures a marvellous soft appearance. Skin tones are captured more faithfully. The maximum working range is reduced by about half in conformity with the loss of light.

8 Flash techniques

8.1 Bounce flash

Bounce flash illuminates the subject more softly and reduces dense shadows. It also reduces the drop in light from foreground to background that occurs for physical reasons.

The swivel reflector ③ of the flash unit can be swiveled horizontally and tilted vertically for bounce flash.

To avoid colour cast in your shots, the reflective surface should be colour-neutral or white.

When tilting the swivel reflector vertically, make sure that it is turned through an angle that is wide enough to prevent direct light from falling on the subject. For this reason the reflector should be tilted at least as far as the 60^ lock-in position.

8.2 Bounce flash with a reflector card

The use of bounce flash with the integrated reflector card ① can bring out highlights in the eyes of human subjects:

• Tilt the reflector head upwards by 90°.
- Pull the reflector card ① together with the wide-angle diffuser ② from above out of the reflector head and forwards.
- Hold the reflector card ① and push the wide-angle diffuser ② back into the reflector head.

9 Program flash mode

In the Program flash mode, some cameras mix the ambient light with the flashlight and – depending on the camera programming – determine whether the flash is to be used as the main light source or for fill-in light purposes. The camera automatically selects the appropriate shutter speed/aperture combination and controls the flash in TTL mode.

Select Program „P“ or a Vari Program (e.g. portraits, depth of field, landscape, sports etc.) on the camera.

10 Automatic AF auxiliary light

The automatic AF auxiliary light ④ is activated in the flash unit by the camera when the ambient lighting conditions become inadequate for automatic focusing.

A bright light is projected onto the subject, which the camera can use to focus. Depending on the camera's activated AF sensor, the AF assist light has a range of approximately 2.5 m to 4 m (with a standard 1.7/50 mm lens).

Parallax error between lens and AF auxiliary light limits the close-up range with the AF measuring beam to approximately 0.6 m to 1 m.

To activate the automatic AF auxiliary light the camera has to be set to the „Single-AF (S)“ or „ONE SHOT“ autofocus mode and the flash unit must indicate flash readiness. Various camera models support only the ca auxiliary's internal AF light. In this case, the automatic AF auxiliary light of the flash unit is not activated (as in the case of mirrorless cameras, measured by compact cameras; see the camera's Low-speed zoom lenses can significantly curtail the range of the AF auxiliary light!

Various cameras support the AF auxiliary light in the flash unit only with the camera's central AF sensor. If a peripheral AF sensor is selected, then the AF auxiliary light beam will not be activated in the flash unit!

11 Flash synchronisation

11.1 Automatic flash sync-speed control

Depending on the camera model and camera mode, the shutter speed is switched to flash sync-speed when flash readiness is reached (see the camera's operating instructions).

Shutter speeds cannot be set faster than the flash sync-speed, or they are switched automatically to the flash sync-speed. Various cameras have a sync-speed range, for example from 1/60 sec to 1/250 sec (see the camera's manual). The sync-speed set by the camera depends on the camera mode, the ambient light, and the focal length of the lens used.

Shutter speeds slower than the flash sync-speed can be set according to the camera mode and the selected flash synchronisation (see 11.3 and 11.4).

[NO TEXT]

If a camera with a between-the-lens shutter (see 11.3) is used, flash sync-speed is not controlled automatically.

As a result, the flash can be used at all shutter speeds. If you need the full light output of the flash unit, you should not select a shutter speed that is any faster than 1/125 sec.

11.2 Normal synchronisation

In normal synchronisation the flash unit is triggered at the beginning of the shutter time (first curtain synchronisation).

Normal synchronisation is the standard mode on all cameras. It is suitable for most flash shots.

The camera, depending on the mode being used, is switched to the flash sync speed. Speeds between 1/30 sec. and 1/125 sec. are customary (see the cameral).

11.3 Second curtain synchronisation (REAR)

Various cameras offer the option of second-curtain synchronisation (REAR), in which the flash unit is not triggered until the end of the exposure time.

This is particularly advantageous when used with lower shutter speeds (slower than 1/30 sec.) and moving subjects that have their own source of light. With second-curtain synchronisation, a moving light source will trail a light streak instead of building one up ahead itself, as it does when the flash is synchronized with the first shutter curtain.

Black-and-white photo of a car on a road at night with blurred city lights and streetlights (no visible text or symbols)

In this way a "more natural" image of the photographic situation is produced! Depending on its operating mode, the camera sets shutter speeds slower than its sync speed.

On various cameras the REAR function is not possible in certain operating modes (e.g., in

certain vari- or subject programs, or with red eye reduction). In these cases, the REAR mode cannot be selected and/or is automatically cancelled or ignored (see camera's manual).

The REAR mode is set on the camera (see camera's manual).

11.4 Slow synchronisation (SLOW)

A slow exposure (SLOW) gives added prominence to the image background at lower ambient light levels. This is achieved by adjusting the shutter speed to the ambient light. Accordingly, shutter speeds that are slower than the flash sync speed (e.g., shutter speeds up to 30 sec.) are automatically adjusted by the camera. Slow synchronisation is activated automatically on some camera models in connection with certain camera programs (e.g., a night shot program, etc.), or it can be set on the camera (see the camera's manual). No settings are necessary on the flash unit, nor is there any display for this mode.

Slow synchronisation SLOW is set on the camera (see camera's manual)! Use a tripod when shooting with slow shutter speeds to avoid blurred images!

12 Triggering control (auto-flash)

On various cameras the flash will not be fired when the prevailing light is sufficient for an exposure. When the camera shutter release is depressed, no flash exposure is triggered.

In various cameras the triggering control only works in the full program mode or "P" program or must be activated on the camera (see camera's manual).

13 Pre-flash function for red-eye reduction

The red-eye effect occurs when the person being photographed is looking for more or less straight into the camera, the ambient lighting is poor, and the flash unit is mounted close to the camera. The flash unit then illuminates the interior of the subject's eyes through the pupils. Some camera models have a pre-flash function for reducing the red-eye effect.

One or more pre-flashes induce the pupils to contract more, thereby reducing the red-eye effect.

On various cameras, the pre- flash function supports only the camera's internal flash unit or an illuminator incorporated in the camera body. The pre- flash function is set on the camera (see the camera's Second curtain synchronisation (REAR) is not possible when the pre-flash function is used.

14 Care and maintenance

Remove dust and grime with a soft dry cloth or silicon-treated cloth. Do not use cleaning agents as these may damage the plastic parts.

14.1 Firmware updates

Flash unit firmware can be updated via the USB port and, within the technical framework, adapted to the functionality of future cameras.

14.2 Flash capacitor forming

The flash capacitor built into the flash unit undergoes physical change if the unit is not switched on for a prolonged period. For this reason it is necessary to switch the unit on for approximately 10 minutes at least once every three months. The power supplied by the batteries must be sufficient to cause the flash readiness indicator to light up no more than one minute after the flash unit is switched on.

15 Troubleshooting

If the flash unit does not function as it should, switch it off for approx. 10 seconds via the button ON/OFF ⑨ . Check the camera settings and that the flash unit connection foot ⑥ is fitted correctly in camera's accessory shoe.

• Clean the visible electrical contacts in camera's hot shoe carefully with a soft cloth, moistened with pure alcohol (e.g. pure ethanol or pure isopropanol).
• Replace the batteries with new batteries or freshly charged rechargeable batteries. The flash unit should function normally again once it is switched back on. If this is not the case, contact your local dealer.

Below is a list of some of the problems that may occur when the flash unit is used. For each item, possible causes and remedies for the problem are listed.

• The AF auxiliary light ④ of the flash unit is not activated.

The flash unit is not ready for firing.
The camera is not in "Single-AF (S)" or "ONE SHOT" mode.
The camera supports only its own internal AF auxiliary light, e.g. mostly with mirrorless cameras, compact cameras and bridge cameras.
Various cameras support the AF auxiliary light ④ in the flash unit only by the camera's central AF sensor. If a peripheral AF sensor is selected, then the AF auxiliary light ④ will not be activated in the flash unit.

Activate camera's central AF sensor, please.

- The reflector position is not automatically adjusted to the current zoom position of the lens.

The camera is not transmitting any digital data to the flash unit.
There is no exchange of data between the flash unit and the camera! Tap the camera's shutter release.
The camera is equipped with a lens without CPU.
The built-in wide-angle diffuser ② is placed in front of the reflector.

• Automatic switching to the flash sync-speed fails to occur.

The camera has a between-the-lens shutter (as do most compact cameras). Switching to flash sync-speed is therefore unnecessary.
The camera operates with shutter speeds that are slower than the flash sync-speed. Depending on the camera mode, there is no switch to flash sync-speed (see the camera's operating instructions).
Fujifilm cameras do not support this function.

• The shots have shadows in the bottom of the image.

Because of parallax error between lens and flash unit, close-up shots may not, depending on the focal length at the bottom of the image, be fully illuminated. Turn the built-in wide-angle diffuser ② in front of the reflector.

• The shots are too dark.

The subject is beyond the maximum distance range of the flash unit.
Note: Using bounce flash reduces the maximum distance range of the flash unit.
The subject contains very bright or highly reflective areas. The metering system of the camera or flash unit is deceived as a result.
Set a positive manual flash exposure correction, e.g., +1 EV at the camera.

• The shots are too bright.

When taking close-ups, make sure to preserve specific minimum illumination ranges to avoid overexposure. The minimum distance from the subject should represent at least 10% of the maximum range.

Maximum distance range = guide number (see table 1) ÷ aperture

Minimum distance to the motive = 0.1 x [guide number (see table 1) ÷ aperture]
