External Flash Units
External fl ash units are more powerful than their built-in
counterparts. Some can function as master fl ash units con-
trolling remote units via optical wireless fl ash control.

You may be unable to test-fi re the fl ash in some circumstances, for ex-
ample when a setup menu is displayed on the camera.
Red-Eye Removal
Red-eye removal is available when an option other than OFF is selected
for F FLASH SETTING > RED EYE REMOVAL and a FACE DETECTION
ON option is selected for G AF/MF SETTING > FACE/EYE DETECTION
SETTING. Red-eye removal minimizes "red-eye" caused when light from
the fl ash is refl ected from the subject's retinas.
