I am asking for opinions on which is better? There are about the same price now since I can get the 10D on Ebay for a little more than the S1 IS, but I am just learning photography. I have a Rebel 2000 film camera now and love it. I have two different lenses for the Rebel that would work with the 10D and a few filters so all I need is the body. Let me know what you think!
