It's not the price of the lens that dictates the AF speed, but the AF mechanism.

Try using the 85L, 50L or 180L one day.

The 85L supposedly AF's noticeably slower than my 85 1.8 according to the lens "gurus". But I don't believe it.

The L is slower.  But it can track people fine in AIServo.

Lens speed comes into play in action photography and AI Servo.  That is where the 70-200 F2.8's for sports  shine.
