Hi all. Briefly, because I know we've discussed these lenses before... I have an 80-200 f/2.8 AF-D, two-ring. (I also have a mk1 one-ring, but since it has something that might be a sticky aperture blade, it's not currently ruling them all.) It's acceptably sharp at longer distances, but gives me trouble at closer ranges. How much of that is the lens sharpness and how much of it is the (alleged) variation in telecentricity throwing the AF off - I can't fit it in the fine tune range when at close focus - I don't know. When I bought it, I tried it alongside a 70-200 VR 2. The newer lens was clearly a bit sharper, but not enough to be worth the extra money to me at the time. However, that was on a D700. Since I got a D800, I've been pixel peeping more, especially since my 28-200 is no longer a viable substitute. By all accounts, the AF-S version is "better". Could I please get a few opinions from anyone who's tried both on whether it's specifically improved at shortish range, whether the AF is any more reliable, and whether the difference is more visible at D800 pixel densities? I bought this lens originally because I wanted some depth of field control (not really provided by my 28-200) and some flexibility in focal length (not provided by my fast primes). It was deliberately a compromise, but I'm currently shooting it almost exclusively at f/5.6 and below to improve the sharpness, at least at shortish range. It would be nice to be able to open up a bit without losing too much performance, though I'm not expecting perfection. I'm off to check some more reviews, but they're harder to find for older lenses like this. Thanks in advance.
