Dave, I used to have Tamron 90/2.5 the earlier version with 49 mm filter threads. I had it with KA adaptall adapter. It was splendid lens. There was just one very small problem with it. Sometimes it would produce a flare/glare circle straight in the middle of the frame. That was with *istD at least. I had to sell it in order to get 31 Limited lens. However it was really good optic.
But if you have FA 100/2.8 why bother? I had a chance to use FA 100/2.8 twice visiting Jostein - truly marvelous piece of gear. Unless you want to loose AF and arrive to slightly smaller size/weight - I see no reason. Boris David J Brooks wrote: > I have one for the Nikon mount, and i really like it.
