order from off to green (Quick Flash

The Quick Flash function enables flash shooting while the flash-ready

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.
