Nikon 80-200mm f2.8 AF-S (w/ collar) Lens This lens is even worse than the 35-70/2.8 I bitch about above. Although I was never stupid enough to buy one, one of my most trusted friends (a pro) did. He got so pissed off over the poor performance of this lens that he bailed on Nikon and switched to Canon. The main problem with this lens is vignetting. He showed me his results and let me play with this lens. Here's an experiment for you: take this lens, open it up to f2.8, point it straight up into the blue sky and take a shot. When the slide comes back, you'll see terrible fall-off in the corners (they're at least a full stop darker than the rest), and a huge white donut in the center (probably 2 stops lighter than the rest). What the hell is Nikon doing? They had a great thing with the oldest 80-200/2.8 AF lens. Can they do nothing right these days?
