I have been shooting with two XT's for quite a while and am surprised at how much this improves my shoot capabilities. No more changing-the-lens-and-missed-the perfect-shot issues!!! I have decided to get a 40D and am selling one of my XT's. let me know if you want a shot at this great camera. Selling for both lens and camera and filter for kit lens for $350.00 and will help with shipping cost.
