Howdy all, I shoot mostly everything and I think it's about time I think about upgrading my body from an XSI. I do too much low light and action-oriented photography to tolerate the XSI's low-light handling. I know there are a lot of threads comparing the 5dm2 to the 7d, but there are none comparing the 7d to a 5dm1? Can you guys tell me about that? How do I know if I need full-frame? I have tried the 10-22 and it is A LOT of fun to use. I wish I didn't need that dedicated lens to get that type of view, but I really enjoy the 1.6x "zoom" on the crop sensors as well. So I was wondering for in the $1000-range, should I try and aim for a 5dm1 or a 7d? Also, I get $2500 in scholarship money in May. I was wondering if I should use that to get a 7d + ~$1000 of camera equipment, or get a 5dm2? Right now, I have a 24-70/2.8L, 100-400L, 85/1.8, and a 50/1.8. What do you guys think? Keep in mind, I shoot everything.
