AF is amazing .. even when AI Servo and AI Focus were set with extreme lateral focus points

All photos were taken with 5D Mark III with 70-200/2.8 L

Those are excellent, especially considering that you were shooting moving targets @ f/2.8 with such a narrow depth of field. What was your keeper rate shooting this event? Are these shots pretty typical or were there a good percentage of out-of-focus shots combined with these?

Does AI Focus work on the 5D3?

I like to see a bird shoot in branches or flying fast.

Auto ISO ... ;)
I used it purposely for a longer shutter time to achive some movement.

What?! Even if its not perfect, if it can tell when to use Servo and One-Shot correctly thats a huge improvement from current AI Focus on older bodies.

Usually there was from 4 to 7 shots OK from 12-15 burst. Biggest issue is not focus - it's the small buffer ... with 6fps it's so so so narrow ...
