I had a 7D. Sold it, got a 60D and a better glass 24-70, 200 etc...
Now I shot w/FF but I still have the 60D. It's only a backup and I use it for macro w/the EFS60, and for wide with the Sigma 8-16, both are awesome lenses. It's an awesome little cam and apart from the lack of AF adjustment I see nothing wrong with it for most uses. Actually I never even needed the AFMA, but maybe I was just lucky. (used that a lot on the 7D, barely use it on 5D2)
It would be great if the ISOs would be cleaner above 800 but the 7D won't make a diff. there anyway..
After all it all depends on your style, your subjects, knowledge...etc.
Just one more thing. If you visit my site and go to portraits, or even if you just sit back and see the main slide I doubt that you could tell which photo was taken with what... think about that for a sec..
