I have a new Canon XTi coming to me in the mail with a 2 gig CF card. I’m really excited about it but I’m wondering how many images I will be able to fit on one 2 gig memory card. Trying to find out if I will need to buy additional memory card(s). I will be shooting at the highest possible resolution (with no image compression). I’m an experienced 35mm SLR photographer and am just now moving into my first DSLR. Thanks!
