Just got this delivered (used) today:
I've played around with it a bit and I already love it; nice and sharp even at f/2.8. The only thing I don't like is that it's not white, but I think I'll learn to deal with that :P Of course, it helps a lot that I got it for quite a bit less than even a used Canon 70-200 f/2.8L :D
Now, I just need it to warm up outside so that I go out and use it!
