Close-up Flash
OTHER OPERATIONS
The flash activation area is inaccurate when the subject distance is between 0.5 and 1.5 m. In this
case, point the flash to the down-most angle (7°) using the Bounce lock release button.
Bounce Shooting
Bounce shooting refers to a method in which the light from the flash is bounced off the ceiling or
walls.
1. While holding the Bounce lock release button, tilt the flash
to the down-most angle (7°). The close-up flash indicator
lights in the control panel.
This allows the light to go all around the subject, resulting in a soft picture without harsh contrast
or shadow.

• The flash light may be blocked when the lens is long or large in diameter. Be sure to perform
test shooting.
Operation
• Do not use this function for any purpose other than close-up shooting. If it is used in normal
shooting, there will be insufficient illumination for the upper half of the picture.

Using the Wide Panel
Various Flash Shooting Methods
Use the built-in wide panel in flash shooting when the lens focal length is set to a wider position
than 12 mm.
The following flash shooting methods are possible according to the camera setup.
• Some flash shooting methods may be unavailable depending on the function and design of the
camera.
• For details on operating procedure, refer to the instruction manual for your camera.
1. When the lens focal length is shorter than 12 mm (24 mm
with the 135 type), the wide panel warming indicator lights
in the control panel.
1. Red eye-reduction flash
Reduces the appear-
ance of red eyes due
to flash emission.
(This does not occur if the camera is not equipped with
communication capability.)
2. Slow sync
2. Slide out the wide panel and place it on the light-emitting
area.
The flash is emitted
with slow shutter.
• The wide panel indicator lights in the control panel.
This makes it possible
to take clear pictures
of subjects against a
night background.
Wide panel indicator
3. Background screen sync
3. Press the ZOOM button to select the firing angle from 8
mm and 10 mm (16 mm and 20 mm with the 135 type).
Slow shutter is used and the flash is emitted immediately
before the end of exposure period.
This makes it possible to take pictures of moving objects
such as car taillights with a streaming effect.
4. Combination with camera’s built-in flash
When the camera in use has a built-in flash, it can be used
simultaneously with the electronic flash.
• When the wide panel is used, the actual guide number
(GN) will be lower than set. In the TTL AUTO, AUTO and
FP TTL AUTO modes, this results in a reduction of the
available shooting range. In the MANUAL and FP MANUAL
modes, this results in a reduction of the optimum shooting
range.
• Be sure to store the wide panel again after shooting.
• To prevent damage to the wide panel, do not flip it in the
upward direction.
• Advanced shooting techniques are possible. For example, you
can bounce the light from the electronic flash off the wall or ceil-
ing while using the camera’s built-in flash for a catch-light effect.
• With certain camera models, the built-in flash may be disabled
when the electronic flash is mounted on the camera’s hot shoe.
• If the wide panel is damaged when it is slid out, the ZOOM
button will no longer be operable. If that happens, disable
the wide panel switch to restore operability (page 61).
■Note
The electronic flash control mode should be set to TTL AUTO or FP
TTL AUTO.

WARNING DISPLAY LIST
Q&A
Q Is multi-flash shooting possible in the TTL AUTO mode?
Camera that dis-
plays warnings
Ref. Page
Warning details
Control panel display
Remedy
A No, it is not possible.
Out of light control
range in AUTO mode
Change the camera’s ISO
speed or lens iris (F) set-
ting.
Q When are test flash activation and auto checking effective?
A Checking the optimum flash activation based on the AUTO CHECK lamp is particularly effec-
tive in bounce flash (in AUTO modes only).
47
Q What will happen if the electronic flash is activated simultaneously with the camera’s built-in
flash?
A In the TTL mode, both flashes emit light simultaneously and the optimum exposure is deter-
mined according to the combined total light intensity (provided that the camera is in the P or A
shooting mode). In bounce flash photography, the camera’s built-in flash can also be used for
catch-light photography (see page 59).
Subject too close in
MANUAL mode
①Change the camera’s
ISO speed or lens iris
(F) setting.
②Change the guide num-
ber (GN) setting.

Q Why does the electronic flash get hot after successive firing?
A The batteries generate heat when flash firing is repeated successively. In this case, use the
electronic flash at intervals until the flash emission section and batteries cool down.
Subject too close in
FP MANUAL mode
①Change the camera’s
ISO speed or lens iris
(F) setting.
②Change the guide num-
ber (GN) setting.
Q Why can’t I mount the electronic flash on the camera?
A The electronic flash cannot be mounted if the lock pin is in the out position. If this is the case,
turn the lock ring all the way in the opposite direction to [←LOCK] until it stops. Once the lock
pin is in the in position, you can mount the electronic flash on the camera (see page 44).
Wide panel request
in all modes
Set the wide panel.
Q Why doesn’t the control mode change when I press the MODE button?
A When the electronic flash is connected to certain types of communication-capable camera,
the flash control mode can only be controlled from the camera.
Downward bounce
in all modes
The light-emitting section
is set at 7° downward.
Cancel this setting except
for close-up flash photog-
raphy.
Q What is the recommended white balance setting for the camera when using the flash?
A The auto white balance mode is recommended. If you use the manual white balance mode,
set the color temperature to 5500K. Note that the color temperature varies depending on the
flash shooting conditions.
Q The light control range is not displayed on the control panel. What is wrong?
A The light control range is not displayed in the following cases:
• When the Extension Tube EX-25 (optional) is used
• When the lens is removed
Wide panel warning
in all modes
The wide panel is set.
Pay attention to the dis-
tance to the subject since
a lower guide number (GN)
is selected.
• During bounce photography
• During light intensity adjustment
• When the ISO speed and lens iris (F) are out of the setting range
Out of light control
range in AUTO
mode
Change the camera’s ISO
speed or lens iris (F) set-
ting.
Q When the Olympus E-1 digital camera enters the sleep mode, the FL-50 control panel displays
turn off. Is this normal?
A Yes, it is normal. When the E-1 enters the sleep mode, the FL-50 does as well. When the
camera wakes up, so does the FL-50.
Q Does the FL-50 also turn off when the Olympus E-1 digital camera is turned off?
A When the E-1 is turned off, the FL-50 enters the sleep mode. When the E-1 is turned on again,
the FL-50 also turns on. When you want to turn off the FL-50, turn off the FL-50 before turning
off the E-1. In addition, when connected to a camera without communication capability, the
FL-50 enters the sleep mode if it is not operated for about 60 minutes.
