❚❚ 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, 0 234), 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 (0 294) 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).
Options range from
1
/60 s (1/60 s) to 30 s (30 s).
