I've had the Vivitar 80-200 f 4.0 and it actually performs well. I'm sure that there are other lenses in this range that produce better results, but this isn't a bad lens. It is a little soft, but does ok for some quick shots. I highly recommend the Canon FD 100mm f 2.8. I bought one of these several years ago, and I'm constantly impressed with the results. It is small, light and spends a lot of time on my camera. You can pick up one of the 100mm lenses for anywhere from 50 to 100 bucks. The Canon FD 300mm f4.0 is a good lens as well. I'm told that the "L" version is better, but I'm happy with my lens. I bought my 300mm for about $150.00. The 28mm f 2.8 is also a nice lens for little money.
