80-200mm f/2.8 Lens Review by Thom Hogan
The earlier "one-ring" or "push-pull" variants are very inexpensive, and many are old now, and rather clunky, but cn be had very cheaply, have slow autofocus, but are a fulkl pound lighter than later models, but the optis are now only good, not very good, not excellent.
The later, low-production 80-200 f/2.8
AF-S is a nice lens, but is fairly hard to find. I had one for two years,and found it to be a good lens.
