Because, I can get a 7D for just a little bit more $$$ than a 60D body. I'm using what I've got, mainly, for concert type photography. I'd consider my skill level at an intermediate level, but continue to learn as I go along. I'm very comfortable with the T1i. I have several EF and EF-S based lenses. If and when I get the 7D, I'll start moving my way to USM lenses. I just wanted to know if anyone had any experience with the 7D and what they thought of it.
