External Flash Units
Use optional external fl ash units for fl ash photography.
Some units support high-speed sync (FP) and can be used
at shutter speeds faster than the fl ash sync speed, while
others can function as commanders 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 ex-
ample when a setup menu is displayed on the camera.
Red-Eye Removal
Red-eye removal is available when FLASH is selected for F FLASH
SETTING > RED EYE REMOVAL . Red-eye removal minimizes “red-eye”
caused when light from the fl ash is refl ected from the subject’s retinas.
Flash Sync Speed
The fl ash will synchronize with the shutter at shutter speeds of 1⁄180 s or slower.
Optional Flash Units from Fujifi lm
The camera can be used with optional Fujifi lm shoe-mounted fl ash units.
Third-Party Flash Units
Do not use third-party fl ash units that apply over 300 V to the camera hot
shoe.
