7D AI servo test

I already posted this on FM, but thought I'd share here. I think the key to the 7D's AF is understanding what modes and CF settings make sense. Anyway, I unpacked my 7D just before lunch, and headed for the nearest park. Nobody was flying, but I did find a few geese swimming to test out obstacles coming in front of a target. The only adjustment I made to the 7D's default AF settings if CFIII-3 (per ruhikant's suggestion), I set that to 1. I set the cam for AI servo, AF point expansion, and then tracked a goose swimming behind another. The sequence is as follows, and is completely flawless (these are 50% crops). I had the AF point on the goose's neck, and had AF in operation the whole time. I did another sequence where I walked while locked onto a goose, and let a tree pass between me. Same results - flawless tracking of the intended subject. My walking caused enough camera shake that the shots have a little blur at 50% so I won't post them - don't want to hear the BS from the trolls.

These have had 0 postprocessing other than resize, and yes I know I accidentally had +2/3 EC. The point is the AF tracking

that is fantastic!

Impressive.

Proof is in the pudding. Nice examples and report. This is evidence enough that some of the AF complaints might be more user-error (for not setting up the AF properly) than the camera.

I've already stated that the first day with my 7D, hardly any image was sharp. I had to reconsider and think about how to use its features, as it's different compared to my 40D.
The next day virtually every image was sharp.

I want to see this done on Hummingbirds - there is a test
