In this mode, pre-flash is performed to measure the optimum flash light intensity and then the
actual flash is emitted.
1. See the following table and set the lens iris (F) according
to the lens in use.
Standard lens iris
Zuiko Digital lenses
ZUIKO DIGITAL ED50mm f2 Macro
ZUIKO DIGITAL 11-22mm f2.8-3.5
ZUIKO DIGITAL 14-54mm f2.8-3.5
F11
ZUIKO DIGITAL ED50-200mm f2.8-3.5
•Even if a different lens iris (F) is used, flash at optimum
exposure is also available provided that it falls within the
light control range of the flash.
•Even if a different lens iris (F) Is used, optimum flash ex-
posure is also available provided that it falls within the light
control range of the flash in use.
• The flash’s light control range varies according to the lens
and shooting distance. See page 42 for details.
2. When flash activation has been performed correctly, the
AUTO CHECK lamp blinks for about 5 seconds after the
shutter is released. If the lamp does not blink, the expo-
sure may be incorrect. In this case, you will need to adjust
shooting settings such as the lens iris (F).
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 Cus-
tom Setup operation (page 46).
• 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 light intensity adjustment value is displayed only when
the value is other than 0.
3. If the camera’s flash adjustment mode is selected, the ac-
tual flash light intensity will be the sum of the light intensity
adjustment value set on the Twin Flash and that set on the
camera.
The light intensity adjustment value displayed on the con-
trol panel applies to the Twin Flash only.
