Hey guys, I was looking into buying a Canon 40d and I had a question. 1. I realize that the 40d has a crop sensor, and i was wondering if an EF-S Lens would be cropped with the 40d? 2. If so, what are my options for a wide angle lens?? I currently have a rebel XT with a 50mm Prime lens and I hate shooting indoors with it because i have to stand so far away from the subject Please Help!!
