I bought this along with the pancake last week. As some of you already know, the pancake didn't work out so well. But I'm very surprised at the IQ and AF speed of the zoom, especially considering the price. I haven't owned a normal zoom in at least 5 years, and to have a 4x zoom that runs from wide to telephoto - it's like, well, my birthday! I'll be using it in the field for the 1st time on Sunday for a local triathlon I'm covering for the paper. I initially bought it with the idea of street shooting, but I can also see using it for snaps - something I really don't do a lot of. (I really don't like pulling out "professional looking" equipment for casual get togethers, so maybe this will be an answer.)
It's funny, I never felt this way about the 70-200 II...
