OK so I have a Rebel XTi with which I have taken about 8000 photos since I got it 6 months ago. I also have 2 lenses 50 f1.8 (my favorite) 17-40 f4. My dad has the ability to get about $2000 in gift certificates to best buy. He offered to get a 5D and then trade it with me for my rebel. My dilemma is that I feel that the 5D is allot of camera. I mean I just got the Rebel and I feel like a 5D is just spoiling me. I am not saying that I don't want it I really really want it but I don't have allot of glass (see above) and it is more conspicuous camera. It is a real step up. I would rather get $2000 in glass but that is not the deal. What kinds of things am I getting from the 5D that I don't have in the Rebel aside from a full frame sensor (which is why I want it less noise)? Do you think the 5D is overkill for me? Also he doesn't have to buy it immediately so I have some time to think about it. Any thoughts?
