Locking exposure on the 7D

If I have all 19 AF points selected the exposures are consistently better even though the metering should be technically weighted to the AF points that have actually achieved focus. But that's not my preferred choice. Most of my shooting is single AF point, next most used is AF point expansion, and Zone AF is a distant third. I normally have Spot and 19 point AF disabled via the menus.

FWIW: I use AE lock quite a bit with the 7D and that has minimized the amount of chimping required after a shot.
