Here's my conundrum... I am outgrowing my XSi for the sports photography I've been doing. In order of necessity from an upgrade, I'd like better ISO range/performance, fps, and AF. Naturally, all of these things are encompassed in the 7d and should, in theory, be the answer to which I should purchase next. However, in being the OCD pixel peeper I am, I'm not certain the 7d is something I could buy and not end up being irritated by its naturally softer images. If all sensors (thus image quality) of this family are equal (is this true or is one actually better than the other(s)?), then I'm thinking that I might just invest in one of those as my XSi has forced me to become pretty good at sports action photography using only center AF point and its inferior (to many others) AF system.
What do you think? All opinions welcome, if they are constructive. At this point, I'm just having trouble justifying the cost of a 7d if I can easily make do with a lesser priced option that has the same, or better, image quality for pixel peepers like myself.
