About Quick Flash
Quick flash enables a flash to be fired before flash-ready, when the pilot
lamp is still green.
Although the Guide No. will be 1/6 to 1/2 that of the full output, quick flash
is effective for near subjects and when you want a shorter recycle time.
Set the drive mode to single shooting. Quick flash cannot be used in the
continuous shooting, FEB, manual flash, and stroboscopic flash modes.
[IliI
Quick flash can also be used during continuous flash shooting.
