I just came across a Tamron (Nikon mount) Tele-Macro AF 90-300mm f/4.5-5.6 lens. Already searched for information out on the internet, then here in TPF, where I found a couple OLD results where someone had one in their gear, but nothing about the price or currant value or performance or anything like that. Seems like a really interesting focal length, especially for outdoors and shooting nature, and at first look it appears to be pretty decently built, with a metal mounting. Also seems to have the 5 contacts (4 together, then one just a little separate) for a digital lens. Has a pretty low serial # 00217##). 58mm front filter size. Tried it on my D80 and it seems to be pretty sharp, nothing like the Nikon 70-300mm I had awhile back. Does anyone have one of these, or know anything about them? Any kind of information would definitely be appreciated.... THANKS!
