Yeah, don't be scared off by the recent threads. I have one and I am one having issues right now too. But when this lens is on, it is definitely on.
I am chalking alot of my problems up to user error. I think that I just need to relearn how to use AI servo because I have about an even percentage of IF and OOF shots when shooting sports.
I would imagine a lot of the reported problems with this lens are user error. From what I've read on FM, there's a "learning curve" with this particular lens, but once you get used to it, the images are spectacular. I'm planning on adding one to my kit eventually.
