The light intensity adjustment must be set to ON in the
custom setup operation (page 27).
• The
indicator appears in the control panel.
Turn dial B to adjust the light intensity in the following steps.
0 → +0.3 → +0.7→ +1.0 ... +3.0
0 → -0.3 → -0.7→ -1.0 ... -3.0
The display shows the light intensity adjustment value ex-
cept when the value is 0, in which case the display shows
the light control range.
If the camera's flash light intensity adjustment function is
also set, the actual flash light intensity will be the total of
the light intensity adjustment values of the electronic flash
and camera.
Note that the light intensity adjustment value displayed on
the electronic flash does not include the value set on the
camera.

Light intensity adjustment value
1.
The control panel shows the current guide number (GN)
together with the optimum shooting distance according to
the camera setup.
2.
Turn dial A to set the GN. (This is also possible by turning
dial B.)
Set the GN so that the optimum shooting distance is equal
to the subject distance.
When the optimum shooting distance is 0.6 m (0.5 m in
case of close-up flash) or less, the displayed figure blinks
to warn that the subject is located outside the flash light
emission area.
The optimum shooting distance varies according to the
camera setup (ISO speed, lens iris (F), lens focal distance
(ZOOM), and shutter speed). See page 30 for details.
Memo:
Assuming that the ISO speed is 100, the optimum shoot-
ing distance can be calculated with the following formula.
Optimum shooting distance = Guide number (GN)/Lens iris (F)
(See page 30.)
The light intensity adjustment must be set to ON in the
custom setup operation (page 27).
