❚❚Flash Control at 1/320 s (Auto FP)
When 1/320s (Auto FP) is selected for Custom Setting e1 (Flash sync speed,
0222), the built-in flash can be used at shutter speeds as fast as 1/320s, while
optional SB-900, SB-800, SB-700, SB-600, and SB-R200 flash units can be used at any
shutter speed (Auto FP High-Speed Sync).
This option determines the slowest shutter speed available
when front- or rear-curtain sync or red-eye reduction is used in
mode P or A (regardless of the setting chosen, shutter speeds
can be as slow as 30s 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 1/60s (1/60 s) to 30 s (30 s).
Choose the flash mode for the built-in flash.
