I have a tamron 200-500 f5.6-6.3, i've had it for a few months but i'm realizing i don't have as much opportunity to use it as i'd like. It's in great condition, AF works fine, no scuffs or scratches on the glass, the only damage is a small scrape on the exterior of the lens hood, which in no way affects its performance. I actually love this lens, it's sharp and has great range and fairly quick AF but i've only had a few opportunities where i really needed to use it. It actually meters as an f4.5-5.6 on my camera, an XSi, although this may not hold true on all cameras. I'm asking around 750 for it, but i would also be willing to trade for a 70-200 f4 non IS and a hundred bucks, or a macro lens of just about any brand, with cash to cover the equivalent. I'm based in the hudson valley, and my preffered method is face to face, cash only. I may be able to work something out with paypal, but i'm really hesitant to do that.
