I´ve been reading about the (more) sophisticated AF system of the 7D and have a question for users who photograph birds. Do you use the spot focus option on (momentarily) stationary birds as I would with my 50D & 400 5.6 lens or are there other focusing options with this camera that are preferable for such shots?

For birds not moving I use spot AF the fine one box inside box. For BIF I use AF point expansion big box in center and 4 small boxes in a cross around it. There are 5 auto focus modes to choose from. There are also other settings where you can pic the priority of af drive or tracking and how quickly it will switch from on object to another also if you want it to try to focus if you lose the subject or stop at that point. There are 13 auto focus/drive custom functions. There are a few good you tube videos on how to adjust them for different purposes.

I tend to use single point expanded (one big point and 4 small ones around it).

Spot AF is great for small stationary birds. Particularly in branches as you can drill right in and park it on their eye.

Ok thanks for the responses. I think I´m getting a better picture (no pun intended) of how the 7D can focus on birds. Just what I wanted to know.

Just because everyone says that you must use a single point, or maybe, just maybe, single point expanded when taking pictures of birds, I tried the opposite. Area AF (Zone and all 19 points), trying to follow a bird against a sometimes busy background and among other birds.

Heres the result (external link). Now I'm not used to shooting birds like this, but I doubt it would be better with just one AF point active.
