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
(modes S and M).

Fixing Shutter Speed at the Flash Sync Speed Limit

%). 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.
