Focus, aputure, exposure time, have to be established before the shot is taken in automatic mode. As previously described, if the shutter button is depressed half way the settings are captured allowing the shutter to release almost imediatly when the button is fully depressed.
I've also got the Canon G7, the manual mode is exellent for a compact.
