I had one of the older versions, and funnily enough it was used on an F that I had in the late 80's/early 90's. I thought the image quality was very poor. I didn't have much spare cash at the time, but thought that investing in a Nikon branded lens was the best option. I persevered with it for a while, but the poor image quality was very frustrating. I now have various other Nikon lenses, most of which are excellent. (although I still don't have a lot of spare cash!).
