Congratulations on your purchase of a
Sekonic Flash Master L-358 Exposure Meter.
This meter provides a wide range of functions that correspond with most
manufacturers camera settings in all formats, which will satisfy professionals as
well as serious enthusiasts.
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-358 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-358 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.

3. When set for incident light
1. 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 q until it
clicks.
2. When the Lumisphere is raised
This is used to photograph 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 light axis of the lens) at the position
of the subject.
3. 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 23) or illumination levels (see page 25), or brightness
difference (see page 23).
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.
•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. Basic Operation
4. When set for reflected light
•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.).
< Using the lumigrid > (Receiving Angle 54°)
1. Remove the Lumisphere
The lumisphere unit is removed by holding the upper
and lower sections of upper and lower double
Lumisphere UP/DOWN ring q and turning it in the
counterclockwise direction while pushing the Lock
lever !4 upward.
2. Mount the lumigrid
To mount Lumigrid @3, align the mount/removal
indicator on the Lumigrid with the mark and, while
pressing it, turn it in the clockwise direction and
secure it in place by raising the Lock lever until it
clicks into place.
3. Take measurements by aiming the lumigrid precisely at the area of the subject to be measured
from the position or direction of the camera.
4. Follow the same procedure to mount the lumisphere.
CAUTION:
•Be sure to avoid touching the light receiving section when mounting or removing the lumisphere
or lumigrid.
< Using the viewfinder > 1°, 5° and 10° accessory non-parallax finder (NP finder)
When measuring with a NP finder mounted, it is possible to measure while confirming the main
portion of the subject with the finder at the position of the camera.
Refer to the NP finder operating manual for details.

•When firing a flash to make measurements, check the camera's synchronizing range and
set the proper shutter speed.
•For flash units with low electric trigger voltage, the flash may not fire. In this case, make
measurements in flash mode without cord (see page 21).
•A new converted f stop is displayed when the film speed is changed after taking the
measurement.
Reference:
・
Setting the shutter speed as measurement (see page 16) of "Flash mode with cord" of Section
2-1.
・
Readings over and under the measuring range, are the same as measurement (see page 16)
of "Flash mode with cord" of section 2-1.
・
If the film speed is changed after the measurement is taken, the new converted measured
value (f stop value) will be displayed.
CAUTION:
•There is danger of electric shock if the meter is handled with wet hands, during rain, in
areas splashed by water or where there is a lot of moisture.
Under such conditions, it is recommended that you use the meter in the flash cordless
mode, and keep the Synchro terminal cap in place.

6. Analyzing measurement function
When measuring flash light, the shutter speed and F stop value (value combining ambient light and
flash light: total amount of light) are displayed in the liquid crystal display and the ambient light and
flash light are each displayed as separate values together with the total amount of light in the dot
scale. In addition, the ratio of flash light to the total amount of light is displayed at that time as a
value in 10% steps. It is possible to use this value for adjustments, for example, when photographing
with a flash in a room illuminated by tungsten lamp light, to emphasize or weaken the tungsten lamp
(ambient) light element (enhancing the flash light of the photograph) to match the photographer's
intentions.
< Example >
If, under certain conditions, the flash light component is
60% and the tungsten light component is 40%, the display
will be as indicated at the right.
1. To emphasize the tungsten (ambient) light (to imbue
the atmosphere with orange-colored tones)
To increase the ratio of tungsten light, use the Set/
change dial t to change the shutter speed to slow.
It is apparent that the flash light component is now
20%. The dot scale also shows the tungsten light
component to be about 2.5 step level higher than
the flash light component.
As a result, images on the film are expressed with
orange tones that give life to the effect of the
tungsten light.
2. To reduce the effect of tungsten light (to realize a
more natural atmosphere)
To decrease the ratio of tungsten light, use the Set/
change dial to change the shutter speed to fast.
It is apparent that the flash light component is now
80%. The dot display also shows the flash light
component to be about 1.5 step level higher than
the ambient light component.
As a result, the images on the film are expressed in
natural color tones.
The settings above are made by adjusting the tungsten (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.

7. Radio flash system
Setting the radio wave transmitter module (RT-32; optional) in the main unit and connecting the
receiver RR-32 or RR-4; optional) to the flash provides a convenient system that enables one person
working alone to measure flash light without a synchro cord, thereby making it possible to take
measurements by triggering the flash from the exposure meter.
The unit has 32 channels when the radio wave transmitter module (RT-32) is mounted.
Channels 1-16 are single channels and channels 17-32 are quad channels, each of which can be
set to 4 sub-channels (a, b, c and d), thus making it possible to control a maximum of 4 flash units.
Meanwhile, there are two types of radio signal receiver, RR-32, capable of 32 channel settings, and
RR-4, capable of 4 channel settings.
< Example with optional radio wave receiver module RR-32 >
1. Open battery cover !6, remove connector cover @2
and set the radio wave transmitter module (optional)
by aligning the connector with the pins.
2. Switch to the radio flash mode by using Set/
change dial t while pressing mode set button !0.
CAUTION
• To prevent damage due to static electricity, release static electricity stored in your body
by touching a metal object nearby (door knob, aluminum window frame, etc.) before
touching the radio wave transmitter module.

CAUTION
• When using quad channels 17-32, it is not possible to terminate this mode unless a sub-
channel has been set (a, b, c or d is displayed).
6. Advanced Functions
3. The set channel number will flicker at this time.
Turn the Set/change dial to set the channel setting.
4. In the Setting mode, "ch" appears on the ISO indicator. At the same time, channel numbers (1
to 16 and 17 to 32) appear on the F indicator. When the channel number is 17 to 32, sub-
channel (A, b, c and d) settings are displayed on the T indicator. In the absence of settings, "-
" appears in the figures.
5. In sub-channel settings, after the channel is set to 17 to 32, the mode button is pressed. Following
this, the 4th figure on the T indicator flickers to indicate that settings may be made. Every time
the mode button is pressed, the flicker shifts from sub-channel No. : 4th figure → 3rd figure →
2nd figure → 1st figure → channel No., while permitting settings for each sub-channel. As the
Set/change dial is rotated in this state, setting ("A, b, c and d" displayed) and resetting ("-"
displayed) alternate. During this process, the indicator continues to flicker to indicate the channel
being set.
→ Set by manipulating the mode set button.
↔ Set by manipulating the Set/change dial.

6. Upon setting completion, the Radio flash mode is selected using the Set/change dial while the
mode button is depressed.
7. Confirm that the unit and the radio wave receiver are set to the same channel number. The
flash unit will fire when the measurement button of the unit is pressed and measurements can
be made at the same time.
Reference:
• Refer to the receiver instruction manual for the receiver operating method.
• Maximum controllable distance of the radio flash trigger system differs depending on the
placement of the device, direction and other factors.
1. Confirm the direct visible range between the transmitter and receiver.
2. Place the devices away from large metal objects, concrete, objects with large moisture
content (both people and trees fall into the category) and so forth.
3. Secure the radio wave receiver module in place by using Velcro tape or a tripod hole.
Be sure that the entire length of the receiver antenna is higher than the flash pack at
this time. Avoid contact between the receiver antenna and metal objects at all times.
4. Depending on the location, there may be cases when the receiver is incapable of
receiving any radio signals whatsoever.
There are various possible reasons for this such as radio signals reflected from nearby
objects. This can generally be resolved by shifting the device slightly in one direction
or another.
In addition, confirm that the device is not placed behind objects that readily absorb or
deflect radio signals such concrete, metal, low hills, etc.
NOTE:
• The radio flash system may be used only in countries where a permit for the control
frequency has been issued by the govenment office in charge.
