Sekonic L-508 CINE ZOOM MASTER Instruction manual

SEKONIC
Zoom Master L-508
Operating Manual
Congratulations on your purchase of a
Sekonic Zoom Master L-508 Exposure Meter.
The Zoom Master L-508 is the latest addition to the extensive line of Sekonic
Exposure Meters which have been market leaders for over four decades.
It was designed to be the ultimate meter, a do-all instrument for the most
demanding pros.
It is the first zoom spot meter on the market. Nine camera-quality lens elements
are required to accomplish its 1° to 4° zoom range.
Its sealed housing and controls make it water and moisture resistant.
Yes, you can use it in the rain, but it is not an underwater meter.
Its large LCD display makes readings easy and lights up automatically in dark
surroundings.
In order not to crowd the controls, four functions which are less frequently used,
are confined to DIP switches, located in the battery compartment.
Because of its many features, the L-508 requires this rather extensive manual.
But since you will never use them all at the same time, once you have learned all
about it, it is simple and its use will become second nature.
The Zoom Master L-508 has undergone extensive quality controls at every step
of manufacture. Please read this instruction manual thoroughly, to be able to take
advantage of its many features and to obtain the long service life it is designed
for. Thank you for your confidence in Sekonic.

4. Replacing battery during measurement or when using the memory function
•
Always turn the power OFF before replacing batteries. If batteries are removed with the power
ON, measurements and settings in memory can no longer be recalled.
•
If after replacing the battery, or during measurements, strange screens (displays that have
not been set) appear in the LCD, or nothing happens, no matter what button is pushed,
remove the battery and wait at least ten seconds and then replace the battery. This allows the
software to automatically reset, and is not a malfunction.
WARNING:
• Never place batteries in fire, short, disassemble, or heat them. The batteries might break
down, and cause an accident, injury or pollute the environment.
5. Auto Power Off function
•
To conserve battery power, the meter will turn off about twenty minutes after last use.
•
Whether the Auto Power Saving feature turns the power off or the Power button 7 is pressed,
the settings and measured values remain stored in memory. When the Power button is
pressed again the last settings are displayed.

4. When set for Incident light
•
Measurement of incident light uses Lumisphere or recessed Lumisphere. You can switch
between Lumisphere and recessed function by firmly rotating the Lumisphere UP/DOWN ring 1
until it clicks.
•When the Lumisphere is raised
This is used to photograph people, buildings, and other three dimensional objects.
•When the Lumisphere is lowered (flat diffuser function)
This is used to photograph manuscripts, paintings or other flat copy. It can also be used for
measuring illumination contrast (see page 20) or illumination levels (see page 22), or brightness
difference (see page 20).
NOTE:
•If the device is used with the UP/DOWN ring in a middle position, distributed light quality
will change, and suitable measurements cannot be made.
•Do not push the Lumisphere down manually.

4. Basic Operation
5. When set for reflected light (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.).
•
The spot metering area can be selected by turning the
Zoom Lens ring 16 while looking through the
viewfinder from the camera position.
•

•Do not look directly at the sun through the viewfinder, to prevent eye injury.
NOTE:
•Do not attempt to take a direct meter reading off the sun, because it may cause damage
to the photo cell.
•If bright light enters through the eyepiece, an accurate exposure cannot be obtained, so
place your eye as close to the eyepiece as possible.
•For correct exposure take measurements of objects beyond 1 meter (3.3 feet).
Reference:
•If the reading will not stabilize because your hands are shaking when taking
measurements, we recommend you place the meter on a tripod.
•If you cannot clearly see the spot circle in the finder, we recommend you select a
Diopter correction lens suited to your own eyesight. (see page 25)
Reference:
• You can set shutter speeds from 30 minutes to 1/8000 seconds. After 1/8000 the shutter
speeds of 1/200 and 1/400 can be set.
• By moving the DIP switch Time 0.5 up or down (see page 8), the shutter speed can
be set in 1.0 or 0.5 (full or half) steps.
• "E.u" (Exposure under) or "E.o" (Exposure over) appears when the combination of
shutter speed and aperture is not possible for the measured light level. Changing the
shutter speed and or aperture with the Set/change dial will allow you to find a
combination that is possible.

on, raise the Lumisphere to the UP position, then take a reading along the camera light
axis.

5. How to use a reflected luminance (cd/m ) meter
1. Make sure that the Index correction value (see page 24) is canceled
2. Set the meter to EV mode (DIP switch) and ISO 100.
3. Set meter for spot reading.
Choose angle setting that is best suited for your subject.
Take the measurement by looking through the viewfinder and aligning so the subject that will be
measured is inside the circle.
4. Convert the measured EV with a conversion table or calculation formula to find the luminance
2
(cd/m ).
6. How to change the compensating function
Exposure compensation can be made in precise 1 /10 step increments in a +/- 9.9 EV range. Exposure
compensation may be desired to match specific requirements, calibration to other light meters, or
setting exposure calibration in 1 /10 steps up or down from standard ISO film speeds, It may also be
desired when requiring compensation for filters, bellows extension, etc. When corrections have been
made, [+ -] is displayed on the LCD.
• Making a plus correction (making the film speed / f
stop index value higher) will result in underexposing
when taking a photograph. Hold the ISO button 11 and
the ISO 2 button 6 and turn the Set/change dial 5
counter clockwise. The +/- will appear on the upper
right part of the LCD. The index correction will change
in +0.1 EV steps up to +9.9.
• Making a minus correction (making the film speed / f
stop index value lower) will result in overexposing when
taking a photograph, Hold the ISO button and the ISO 2
button and turn the Set/change dial clockwise.
The +/- will appear on the upper right part of the LCD.
The index correction will change in -0.1 EV steps up to
-9.9.
NOTE:
• Make corrections after a sufficient number of test in actual photographic conditions, to
suit your needs.
• Corrections made effect every mode of the meter.
If recalibration has been made for specific purpose do not forget to return to original
zero settings.

9. Safety Guide
Please keep in a location where an infant cannot reach and accidentally
get the strap wrapped around his neck. There is danger of strangulation.
Never place batteries in fire, short, disassemble, or heat them. The
batteries might break down, and cause injury or pollute the environment.
Do not look directly at the sun through the viewfinder, because of
potential eye injury.
If you are operating the exposure meter in areas under wet conditions or
high humidity, keep the sync post covered. If you are using flash in
Maintenance Notes
• If your meter is splashed with water, wipe immediately with a soft dry cloth.
• Avoid applying excessive force on the rubber seal of the battery compartment cover.
Do not attempt to remove the rubber seal of the battery compartment cover.
• If the rubber seal's surface is damaged, water or moisture may enter and damage the
meter. If this has happened, you must send your meter to the Sekonic Sevice Center
in your country.
• Keep the surface of the Lumisphere and the front and rear surface of the Zoom lens
free from dust, dirt, and scratches, which could affect accuracy.
• Never use organic cleaners (like thinner or benzene). Clean with soft dry cloth.
