About Quick Flash

The Quick Flash function enables flash shooting while the flash-ready lamp is green (before the flash is fully charged).

The guide number is 1/2 to 1/6 of the full output, but it is useful for shooting with a faster recycling time at a short shooting distance. Set the drive mode to single shooting. You cannot use Quick Flash when continuous shooting, FEB, manual flash or stroboscopic flash is set.
