A Fixing Shutter Speed at the Flash Sync Speed Limit
To fix shutter speed at the sync speed limit in mode S or M, 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.
A Auto FP High-Speed Sync
Selecting an “Auto FP” option allows compatible flash units to be used
at the highest shutter speed supported by the camera (0 314).
Auto
FP high-speed sync is enabled automatically at shutter speeds faster
than the chosen flash sync speed (
1
/ 320 s or
1
/ 250 s depending on the
option selected), allowing wider apertures for reduced depth of field
even in daylight.
If the shutter-speed displays in the control panel and
viewfinder show a value equal to the flash sync speed in modes P and
A, auto FP high-speed sync will still be activated if the actual shutter
speed is even slightly faster.
