External Flash Units
Flash units can be mounted on the hot shoe or connected
via the sync terminal.
External  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  ash sync speed, while others can
function as master  ash units controlling remote units via optical
wireless  ash control.

You may be unable to test- re the  ash in some circumstances, for
example when a setup menu is displayed on the camera.

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>

eye” caused when light from the  ash is re ected from the subject’s retinas.
