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.

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/
