I have a Rebel XTI as a backup, and a 40D as a main. I want to sell my XTI, use my 40D as a backup and purchase a 7D as a new main. Here is why I feel I need a 7D. Talk me out of it, if you can. 1. Better noise handeling than my 40D/XTI. 2. Larger print sizes. 3. Better AF system (I shoot sports and would like to use servo with AF) 4. More robust body, it is very cold in SD (-20F last week) and I am afraid to take my 40D outside. I am missing lots of great winter shots. The price is what really concerns me. If I buy this 7D I don't want to have to upgrade in a few years (7D mII or comparable for example). The price of the 40D never really bothered me to upgrade.
