just to let u guys know these canons along with most of their other cameras have a soomlense or shutter problem where the gears that control them break very easily and the camera fails to initialize. My friend has this exact one and it failed in less than 2 months time, he never dropped it or anything, the gear that controls the shutter broke all the teeth off, he could tell because right before it stopped working completely there were a bucn of white spots on the picture (bits and peices of gear material on the digita CMOS)
Anyway, search on google there's a class action lawsuite against Canon for this.
