- Modes enclosed in dotted lines can only be selected with custom setting. (See page 40)
- Modes enclosed in lines can only be selected with L-758DR. For L-758D and L-758CINE, they can be selected when Optional Radio Transmitter Module is installed. (See page 28)
- In addition to exposure reading, L-758CINE displays FC or LUX in incident light mode, and FL or cd/m² in reflected light mode.(See page 34)
Reference:
• Available light is continuous light like natural light (sunlight) or tungsten lamps and florescent lamps like pulsing light sources.
- Flash light is a brief, intense burst of light made by such as electronic flash units or flash bulbs.
3. Incident Measurement Mode
Incident light measuring is the measurement method that employs either the Lumisphere or Lumidisc functions. Measurements should be with the Lumisphere aimed towards the camera direction from the subject position.

natural_image
Illustration of a person using a sun to observe a camera and surveying instrument (no text or symbols)- You can select extended or retracted lumisphere measuring positions by rotating the Lumisphere retracting ring ① (clockwise or counter-clockwise) until it clicks into position.

text_image
SEKONIC Extended Lumisphere SEKONIC Retracted Lumisphere (Lumidisc)- When the Lumisphere is extended. (3-D Light Measurement)
This is used to measure people, buildings, and other three dimensional objects.
Measurements are basically made by the method of measuring with the lumisphere aimed in the camera direction (more precisely, in the direction of the lens axis) at the position of the subject.
- When the Lumisphere is retracted (flat diffuser function)
This is used to measure manuscripts, paintings or other flat copy. It can also be used for Contrast function (see page 32) or measuring illumination (see page 34).
NOTE:
- If the light meter is used with the Lumisphere retracting ring in a middle position, distributed light quality will change, and suitable measurements cannot be made.
- Do not push the Lumisphere down with your finger or hand. Always use the Lumisphere retracting ring.
- If the lumisphere becomes soiled, wipe it with a soft, dry cloth. Organic solutions (paint thinner, benzene, etc.) must not be used under any circumstances.
4. Reflected Measurement Mode (spot metering)
This method measures the brightness (luminance) of the light reflected from the subject. It is useful for distant objects such as landscapes, when you cannot go to the position of the subject, or for metering subjects that generate light (neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.).

natural_image
Illustration showing a person observing a sun and a camera on a tripod, with no text or symbols present.- Take the measurement by aligning the circle inside the viewfinder with the subject area to be measured.
- The black circle A in the finder indicates the measurement range. The light receiving angle is 1 degree.

text_image
A 125 0(Display in spot viewfinder)
< Diopter Adjustment >
Turn the eyepiece ② and adjust the diopter so that the circle in the finder is clearly visible when you look into the finder.
< Step-Up Ring (Lens Hood)>(optional)
The step-up ring (30.5mm → 40.5mm), available as an optional accessory, makes it possible to mount step-up rings and filters. This simplifies the setting of exposure without the troublesome correction calculation of polarizing filters, etc. (see page 52)
The step-up ring can also be used as a lens hood to prevent lens flare and erroneous light measurements from glare, it also protects the spot lens from scratching, soiling, etc.
1. Measuring ambient light
In this measurement mode, we have the choice of shutter priority mode, aperture priority mode or EV mode. Hold down the Mode button ⑩ and turn the Jog wheel ⑤ to select ambient measurement mode ⚙️.

2-5 Flash analyzing function
When measuring flash light, the shutter speed and F stop value (combining ambient light and flash light: total amount of light) are displayed on the LCD screen and the ambient light and flash light are each displayed as separate values along with the total amount of light (combined flash and ambient) on the analog scale. In addition, the ratio of flash light to the total amount of light is displayed as a percentage (in 10% steps) at the sametime. The ratio of flash to the total amount of light is useful when a desired flash to ambient lighting ratio is needed.
Under certain conditions, if the flash light output is 60% and the available light output is 40%, the LCD screen will display the flash measured value on the analog scale with a faster blinking icon than the total exposure blinking icon.
-
To emphasize the ambient light (to create a more natural lighting condition) increase the ratio of ambient light,(use the Jog wheel ⑤) by changing the shutter speed to a slower setting.The ratio of flash light in the total exposure will be reduced (as shown in the diagram to the right - 20%).The analog scale also shows the ambient output to be about 2.5 stops higher than the flash light output.As a result,images will exhibit a natural lighting quality with flash filled shadows without an over powering presence of flash.
-
Toreduce the effect of ambient light decrease the ratio of ambient light, (use the Jog wheel) by changing the shutter speed to a faster setting. The ratio of flash in the total exposure will be increased (as shown in the diagram to the right – 80%) The analog scale also shows the flash light output to be about 1.5 stops higher than the ambient light output.

- Slower shutter speeds allow more available light to reach the film or digital camera sensor, and faster shutter speeds reduce the amount of available reaching the film or sensor.
- The settings above are made by adjusting the ambient light by the shutter speed. It is also possible to modify the ratio by adjusting the flash light (when changing the distance between the flash and the subject or when changing the amount of light of the flash). When using this method, re-measure each time the flash light is adjusted.
2-6 Wireless Flash Radio Triggering
With the Radio Transmitter module plugged into the meters radio socket and a Receiver or Transceiver (PocketWizard ^® ) connected to one or more electronic flash units, the meter provides a convenient system that enables one person working alone to measure flash output without the need of a sync cord. Pressing the Measuring button simultaneously triggers the flash and measures the flash output.
The L-758DR/758D/758CINE has 32 triggering channels with the RT-32N radio triggering module (built-in for L-758DR, optional for L-758D/758CINE). Channels 1-16 provide single triggering, while channels 17-32 offer Selective Quad-Triggering control. Selecting one of the Quad-Triggering channels (17-32) provides control of up to four zones of lighting indicated as a Zone letter (A, B, C and D). Selecting or deselecting a zone is quick and easy with the Quad-Triggering buttons (A,B, C or D). In order to trigger a flash units set for Quad-Triggering, the electronic flash unit must be connected to a PocketWizard MultiMax or a n electronic flash that already has a PocketWizard built-in. The PocketWizard Plus or Plus II can be triggered by the L-758DR using channels 1-4.
< Example with optional 32 channels receiver >
For L-758D/758CINE: Open the battery compartment cover ⑮, remove connector cover ⑲ and set the RT-32 Radio Transmitter module (optional) by aligning the connector with the pins.

CAUTION:
- It is not possible to activate Quad-Triggering control without first selecting a channel 17-32, and a Quad-Triggering zone (A, b, c or d).
-
To prevent damage due to static electricity, release any static electricity from your body by touching a metal object nearby (door knob, aluminum window frame, etc.) before touching the radio transmitter module.
-
Upon setting the channel and Quad-Triggering zones, press the Measuring button ⑭ to enter your settings. The display will automatically go to the main LCD screen and Wireless Flash Radio Triggering mode will be activated or rotate Jog wheel ⑤ to set wireless flash radio triggering mode or wireless multiple flash radio triggering mode.
- Confirm that the meter and the radio Receiver or Transceiver are set to the same channel number. The flash unit will fire and measure the light output when the measuring button on the meter is pressed.
NOTES:
- When firing a flash, if the flash brightness is 8EV lower than the ambient light, the meter may fail to detect the light. In this case, make measurements using the cord flash mode (see page 21).
- Rapid start fluorescent lamps and special lighting are sometimes mistaken for flash, and accidentally measured. In this case, make measurements using the cord flash mode (see page 21).
- The waveform of flashbulb have a slight slope and there is a possibility that light meter cannot recognize the flashbulb in Cordless flash mode. In this case, be sure to take measurement in Cord flash mode (see page 21).
Reference:
- Refer to the radio Receiver or Transceiver instruction manual for the recommended operating method.
-
Maximum distance of the wireless flash radio triggering system can vary depending on the placement of the remote Receiver or Transceiver, direction of the radios antenna, distance from a large body of water or concrete wall and other possible factors.
-
Confirm the range between the meter (transmitter) and Receiver or Transceiver.
- Place the meter and Receiver or Transceiver away from large metal objects, concrete, objects, large moisture content (both people and trees fall into the category) and so forth.
- Secure the radio Receiver or Transceiver in place by using Velcro tape or a 1/4-20 mounting screw. Be sure that the entire length of the Receiver or Transmitter antenna is higher than the flash pack. Avoid contact between the Receiver or Transceiver antenna and metal objects at all times.
- Depending on the location, there may be cases when the Receiver or Transceiver is incapable of receiving any radio signals whatsoever. There are several possible causes for this such as radio signals reflected off of nearby objects. This can generally be resolved by shifting the meter (Transmitter) or the Receiver or Transceiver slightly in one direction or another. In addition, confirm that the Receiver or Transceiver is not placed behind objects that readily absorb or deflect radio signals such concrete, metal, low hills, etc.
NOTE:

1. Calibration testing for exposure profiling
A camera exposure profile plays two main roles.
[1] It can be used to display on a light meter the unique dynamic range and clipping point of the digital camera you are using.
[2] To display more accurate exposure values on the light meter, it records unique variations in the camera, lens shutter speed, aperture, etc. that you are using and reflects them in the exposure display.
The L-758DR/L-758D/L-758CINE can be programmed to stored, recall and display up to three different digital cameras.
Below are the following settings that can be programmed into the L-758DR/L-758D/L-758CINE.
1. Compensation value
Compensation value (aperture and shutter speed) can be programmed for a specific camera and hand-held meter. Compensation adjustment is within a +/- 5EV range in 1/10 step increments.
2. Dynamic range (-)
The point at which a given lighting situation (pre-exposure) has surpassed the responds level of a sensor and alerts the shooter of a under exposure situation (Pre-Exposure Warning). These point can be custom set from -7EV to 0EV in 1/10 increments.
3. Clipping point (-)
The point at which the sensor has reached its maximum reproducible shadow details without pixel noise or grain. Dynamic range (-) adjustment is set from -7EV to 0EV in 1/10 step increments.
4. Clipping point (+)
The point at which the sensor has reached its maximum reproducible highlight details without blooming or highlight block up. Dynamic range (+) adjustment is set from 0EV to +7EV in 1/10 step increments.
5. Dynamic range (+)
The point at which a given lighting situation (pre-exposure) has surpassed the responds level of a sensor and alerts the shooter of an over exposure situation (Pre-Exposure Warning). These point can be custom set from 0EV to +7EV in 1/10 increments.

3. How to use Camera Exposure Profiling
3-1 Selecting Camera Exposure Profiling
Preset Camera Exposure Profiles (Camera 1, 2 and 3) can be recalled.
1) Hold down the ISO 1 button ⑪, and press the MID.TONE button ⑳ to select the desired Camera profile (Camera 1, 2 or 3).
NOTE:
- Holding down the MID.TONE button first and pressing ISO1 button makes the last measurement value "Mid.Tone" as standard value. Be sure to hold the ISO1 button first and press the MID.TONE button to select the desired camera profile.
3-2 Analog scale
The analog scale indicates the last measured value, memorized, contrast, and averaged value, clipping point and dynamic range on the LCD. As you can see in the figure on the right, it is composed of four scales.

The Aperture scale can be displayed in all mode except Aperture priority mode. Aperture values are displayed as measured values (last measured value, memorized, contrast and averaged value) on this scale.

ISO1 100 T F 2.83 125 Aperture scale3-2-2 EV scale
It can be displayed in all modes except multiple flash mode. Aperture scale or EV scale can be switched by holding the Mode button ⑩ and pressing the AVE./△EV button ④. The EV scale can display a memorized measured value (ex. Incident reading) as a standard value (Mid.Tone), and display up to nine memorized values on the EV scale as +/- 7EV from the MID.TONE in 1/3 step increments.

SEKONIC 125 F 5.6s AVE..DEV Memory button MID.TONE B1) After taking a measurement by pressing the Measuring button ⑭, pressing either the Memory button ⑦, MID.TONE button ⑩ or AVE./ △ EV button ④ stores the measured value as zero in the middle of the EV scale representing the MID.TONE value. Pressing MID.TONE button will display a blinking “▲” on the scale. Pressing AVE./ △ EV button will display a blinking “■” on the scale. If the MID.TONE button is not pressed, the measured value will be set automatically in the middle of the EV scale. (See the section “3-2-3”)
Reference:
- In custom setting (see page 40), it is possible to select which value (last measurement, first memorized value or last memorized value) will become the middle of the EV scale if the MID.TONE button is not pressed.
2) The EV scale displays Clipping points(+/-), Dynamic range(+/-) and Mid. Tone with a triangle "▲" icon.
3) Measured value exceeding Clipping point will be displayed as a slow blinking "▲" icons. Measurements that exceed the Dynamic range will be displayed as fast blinking "▲" icons.
