External Flash Units
Flash units can be mounted on the hot shoe or connected
via the sync terminal.
External fl ash units are more powerful than their built-in coun-
terparts. Some support high-speed sync (FP) and can be used at
shutter speeds faster than the fl ash sync speed, while others can
function as master fl ash units controlling remote units via optical
wireless fl ash control.
O
You may be unable to test-fi re the fl ash in some circumstances, for
example 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 G AF/MF SETTING >
FACE/EYE DETECTION SETTING is ON. Red-eye removal minimizes “red-
eye” caused when light from the fl ash is refl ected from the subject’s retinas.
