Displayed according to the
focal distance of the lens.
<AUTO>
In this mode, the flash light intensity is controlled automatically according to the lens iris (F)
setting and the amount of light input to the auto light receptor.
Light control range
1.The control panel shows the light control range according
to the camera setup.
The light control range is not displayed if the camera setup
(ISO speed and lens iris (F)) does match one of the us-
able ISO speed/lens iris (F) combinations.
In this case, the ISO and F indicators blink to alert you.
Change the camera setup (ISO speed and/or lens iris (F)).
2.Confirm that the distance to the subject is within the light
control range.
If not, adjust the lens iris (F) or the subject distance.
The light control range varies according to the camera setup
(ISO speed, lens iris (F) and lens focal length (ZOOM)).
Memo: Test flash activation
Flash activation can be tested before actually releasing
the shutter.
Press the Test button for test flash activation.
The light control is OK when the AUTO CHECK lamp blinks
for about 5 seconds after the test flash activation.
If the lamp does not blink, change the lens iris (F), ISO
speed, subject distance, etc.
•The light check by means of test flash activation is pos-
sible only in the AUTO mode.
Light control range
<TTL AUTO>
In this mode, pre-flash is performed to measure the optimum flash intensity and then actual flash
is performed.
Displayed according to the
focal length of the lens.
1.The control panel shows the light control range according
to the camera setup.
2.Confirm that the distance to the subject is within the light
control range.
If not, adjust the lens iris (F) or the subject distance.
The light control range varies according to the camera type
and camera setup (ISO speed, lens iris (F) and lens focal
distance (ZOOM)).
3.When flash activation has been performed correctly, the
AUTO CHECK lamp blinks for about 5 seconds after the
shutter is released.

■Light intensity adjustment
The flash light intensity can be adjusted between +3 and –3.
The light intensity adjustment must be set to ON in the
custom setup operation (page 61).
•The indicator appears in the control panel.
1.Tu rn dial B to select a light intensity adjustment value in
the following steps.
(This selection is also possible with dial A.)
0 +0.3 +0.7 +1.0 ... +3.0
0 –0.3 –0.7 –1.0... –3.0
2.The display shows the light intensity adjustment value ex-
cept when the value is 0, in which case the display does
not show the light control range.
3.If the camera’s flash adjustment mode is selected, the
actual flash light intensity will be the total of the light
intensity adjustment value set on the FL-50 and that
set on the camera. The light intensity adjustment value
displayed is that of the FL-50 only.
