I have several friends that own come Cannon products. One has a T2 and the others are just point and shoot models. I'd like to get them something like a battery card and/or battery for these cameras (the kind of thing most people don't buy themselves) but I'm having a hell of a time finding anything on Cannon's site that gives the maximum size of the flash card they use? Finding a battery or battery pack is easy. I'm just stumbling over the memory card size.
