Great shots, but...
Why don't you tell us something we don't know already.
Any one who has used the camera knows what is possible, and, that there is no replacement for good technique. By panning your shots, and following the action the autofocus could take 10 times longer and still keep up wiht he action.
The demand for faster autofocus comes from people I think who think they should be able to randomly point at anything at all and have the shot within a microsecond. Nobody's technology is that good.
Somewhere back a few months is a similar thread great soprts shot taken with a manual lens, one shot only not a sequence, when people were demanding 10 FPS so they could catch the moment. Same thing applied there, knowing what you're doing counts.
ps, I really like the expression in the first shot, OUCH!
