That's great. I think you're going to be very happy. Did you have an EOS 3, before? I think the AF on the EOS 3 is a better, but the overall image quality of the 10D is way better than 35mm film. I love the quality of images that come out of my 10D. That CMOS sensor is really nice.
What lenses are you going to be using? Do you shoot wide? Do you have a wide lens to go with it?
