took my new toy to my favorite park this afternoon, to see what it'd do. it'll take a bit of getting used to, but i think i'm gonna like it... here's a male common merganser in flight...
You will like the 7D. The firmware was updated earlier this year. Make sure you have version 2.0.3. If you don't, you can go to the Canon website and follow the instructions on how to download it to your camera.
The auto focus system of the 7D is fairly sophisticated. Owner's manuals usually put me to sleep, so I bought the "Short Course" manual for the 7D, which helped me set it up to photograph birds in flight. I marked up the pages with notes on the settings I chose in case I decide to go back and change them at a later date. http://www.shortcourses.com/store/canon-7d.html

yeah, it seems quite a bit different from the other Canons i've used. i had the AF set for single-point expansion for these, thinking that might make it easier to keep moving targets in focus, but on some of my shots, it looked like the AF locked on to the wrong thing, or the wrong part of the right thing, so i think i'll go back to my old standby center point only.

The updated firmware increases the upper range of the auto ISO setting from 3200 to 6400. This is very helpful for someone like me who shoots in M mode with a set shutter speed + f stop and lets the ISO float via the auto ISO setting. The update shows all the available ISO settings when you press SET on the quick control dial as the ISO box is highlighted on the the "Q" screen.
Regarding the auto focus locking in on something unintended. There is a sensitivity adjustment when setting up the auto focus via the menu. The smaller the number (less sensitive), the less likely the camera will lock in on an object which pops up between you and the target. This is very important when photographing birds in flight, as you don't want the camera locking in on intervening bushes or tree limbs as the bird flies past.
I think the Short Course book on the 7D is $$ well spent if like me, you find the owner's manual difficult to follow.
