I've read that the AF speed is good, but not as good as the big primes....which has me questioning weather I want this lens for shooting sports/action....any thoughts?

I got it for sports primarily. I am shooting HS football this thursday, so I will find out. I will use it on a 1DX so I don't think the loss of a stop (from 2.8 on my old 400) will be much of an issue, but I expect to get a lot more usable shots from the zoom. I think the difference in focus speed is on par with my old 400. I am sure the difference between it and the new super teles is only milliseconds and wouldn't be noticeable.

There are no cast offs. These are not machine assembled lenses, they are hand assembled, and if the lens does not meet specs, parts are replaced until it does.
Sorry, I mean the castoff elements, not whole lenses :D Canon can make as many of the metal or electronic parts as we'd all want, but it's those lens elements that take forever, and there is no bondo to fix a 'minor' imperfection. That's where I wonder what the keeper rate is like for the larger pieces of glass.

I would like to read your opinion after you shoot your game on thurs. Bryan at TDP has gone on record as saying is the AF performance isslightly less than the big whites....so I'm curious.
