Cover the subject with the
viewfinder's AF frame and
press the shutter button
halfway.
• When the shutter button is
pressed halfway, the camera
focuses the subject and the
flash coupling distance indicator
bar and aperture value are dis­
played in the flash unit's LCD
panel.
~J Check the shooting distance indicated on lens’ distance scale.
8 Check the coupling distance indicator bar in the LCD panel.
If there is a difference befween the shooting distance (indicated on
the lens’ distance scale) and the LCD panel’s coupling distance indi­
cator bar, adjust the aperture until the coupling distance indicator
matches the shooting distance.
• The coupling distance indicator bar can also be adjusted by changing the
flash output power level
If there is a large difference between the shooting distance and the coupling
distance display, change the flash output power level and refocus the subject,
then adjust the aperture until the distance indicated on the coupling distance
display is the same as the shooting distance.
For more precise exposure control, use a commercially-available handheld
flash meter.
Make sure the shutter speed
and aperture value displayed
in the viewfinder are not blink­
ing and that the flash charge
indicator i is lit, then take
the picture.
