> Does anyone have any experience or comments on the following lenses? Not with either, but I'd just add that, in case anyone's looking in the "500mm Zooms" category for one, my experience with the mf Tokina AT-X 150-500/5.6 is only so-so. It's a very well built lens, but is good only up to about 300mm or so, and above that gets a bit soft. (The AT-X 100-300/4 is a better lens from 300mm down, too, anyway...)
