1/250 s 
(Auto FP)
Auto FP high-speed sync is used when a compatible flash 
unit is attached. If other flash units are used, shutter 
speed is set to 
1
/
250
s. When the camera shows a shutter 
speed of 
1
/
250
s in exposure mode P or A, auto FP high-
speed sync will be activated if the actual shutter speed is 
faster than 
1
/
250
s. If the flash unit supports auto FP high-
speed sync, shutter speeds as fast as 
1
/
8000
s can be 
selected by the camera (modes P and A) or by the user

Fixing Shutter Speed at the Flash Sync Speed Limit
To fix shutter speed at the sync speed limit in shutter-priority auto or 
manual exposure modes, select the next shutter speed after the 
slowest possible shutter speed (30 s or 
%). An X (flash sync indicator) 
will be displayed in the viewfinder and control panel.

Auto FP High-Speed Sync
Auto FP high-speed sync allows the flash to be used at the highest 
shutter speed supported by the camera, making it possible to choose 
the maximum aperture for reduced depth of field even when the 
subject is backlit in bright sunlight. The information display flash 
mode indicator shows “FP” when auto FP high-speed sync is active.
