I bought one - an early non-D version - and I thought it was great at first. Then after taking it on a long trip, and reviewing several hundred slides taken with it I thought many seemed to have lower contrast and lower resolution than I expected. I sent it to a well-known Nikon lens specialist and he told me that the lens had a defective component, and that there were no parts available for replacement. And that the problem was fairly common in non-D lenses. So, if you want to try one, avoid the early ones for sure. They are of course, the cheaper ones.
