We've just jumped into a DSLR. We sprang for a used D80, an 18-135, and 50 f/1.8. I definitely like the speed of the 50. I definitely want something longer than 200. I definitely don't have the money to shell out for a nice, fast, long lens. In the cheap, longer than 200 range, it seems like there are a few options, most of which are 70-300, all of which are slow. Sigma 70-300 non-APO (~$120) Sigma 70-300 APO (~$180) Tamron 75-300 (~$130) Tamron 70-300 (~$180) Nikon 70-300 non-VR G (~$140) Nikon 70-300 non-VR D (~$300) Nikon 70-300 VR (~$470) Does anyone have comparative experience with these lenses? While I've seen plenty of posts happy with the 70-300 VR, does anyone have experience with any of the cheaper lenses? Am I missing any good alternatives that match my "cheap, longer than 200" parameters? I've been leaning toward either Sigma or the newer Tamron because they feature macro modes which bring the minimum focal distance down to about three feet, which is useful as I'm planning to ask this lens to double for macro work for the time being. I suspect this question has been asked before, but I couldn't seem to find such a thread using the cafe's search. Thanks for any feedback.
