Flash Control at 1/320 s (Auto FP)
When 1/320 s (Auto FP) is selected for Custom Setting e1 (Flash
sync speed, 0 281), the built-in flash can be used at shutter
speeds as fast as
1
/320 s, while optional SB-900, SB-800, 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 using front- or rear-
curtain sync or red-eye reduction in
programmed auto or aperture-priority auto
exposure modes (regardless of the setting
chosen, shutter speeds can be as slow as 30 s
in shutter-priority auto and manual exposure 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).

D The Flash-Ready Indicator
When the flash fires at full power, the flash-indicator in the camera
viewfinder will blink to warn that the resulting photograph may be
underexposed.
Note that the flash-ready indicators on optional flash
units will not display this warning when 1/320 s (Auto FP) is selected.
