I love it when someone says a lens (or body) won't work for something like fast action, then someone posts several pictures of fast action (like dogs at play) taken with that lens.
I think this is because people are discussing different things.
The 85L is perfectly capable of tracking action if it is locked on a single athlete (or dog, or whatever). That actually is not very demanding of AF speed.
What the 85L is not good at is changing subjects quickly while shooting sports. So if I'm shooting volleyball and I want to shoot the pass, the set and the hit on one series, the 85L in general will not allow me to make all three shots because it will not shift from subject to subject fast enough.
Same thing for basketball. I can track a guard coming across the top, but if that guard suddenly dishes off the ball to a forward that immediately goes up, I know I will almost always have OOF shots on the layup.
If you are trying to follow one athlete at a time the 85L is fine. If you are trying to work fast and get every athlete on a team at peak action (meaning you catch the peak action on every play) then the 85L is not very good at it.
