I have the 7D. I have two 35mm bodies that I use with most of my lenses also. I don't think I've ever wished I'd bought something else. It is a great camera. There are so many different cameras out there and most, if not all, are great. For me it was an easy choice. I liked the fact that the AS (anti-shake) was built into the body and not the lenses. This turns pretty much every lens into an AS lens. Not to mention all of the controls are pretty much dial, knob, or button driven. there aren't too many that are menu driven. The ones that are, aren't ones you'd need to use/change while shooting. this makes adjustments very easy, most can be done with the camera still up to your eye. Keep in mind this is all on the 7D. The 5D is pretty close, but some options that are dail, knob, or button driven are only accessible through the menu. That fact not withstanding, the 5D is still a great camera.
