Great info Tim, thanks for the update. Anecdotally, I've been quite happy with the results of my FA 45-85mm, FA 80-160mm and FA 300mm. I will get around to some more formalized tests at some point, but so far haven't wanted to spoil the fun of just shooting with them and getting to know the feel of the system.
Hopefully you can get your 45-85 sorted; aside from that one issue with it you seem to have the classic FA glass in good shape. I want to build out my FA set a bit more but in the short term will try my eye at manual focus with A versions of the 75mm, 120mm, and also a 67 105mm.
As I mentioned in another thread, I returned my FA 55mm. I just don't know if that lens is going to come through for my kind of subject material in landscapes and architecture...
