It is a good cam. The only problem is there seems to be some blurryness. Perhaps you need to get a tripod or start shooting in Tv mode. The fast shutter will cut down on the blur. Otherwise they are very nice. Keep shooting.
Tv mode is canon's way of saying shutter priority. Av mode is aperture priority. Do you use a tripod? If not, maybe you can put it on something solid and use the timer function.
