Auto FP High-Speed Sync
When 1/250 s (Auto FP) or 1/200 s (Auto FP) is selected for
Custom Setting e1 ( Flash sync speed , 0 345), the built-in flash
can be used at shutter speeds as fast as 1 /
250
s or 1 /
200
s, while
compatible optional flash units ( 0 435) can be used at any
shutter speed (Auto FP High-Speed Sync).
This option determines the slowest shutter speed available
when using front- or rear-curtain sync or red-eye reduction in
mode
P or A (regardless of the setting chosen, shutter speeds can
be as slow as 30 s in S and M modes or at flash settings of slow
sync, slow rear-curtain sync, or red-eye reduction with slow
sync).
