I might have been a little inspecific in my initial posts - I am not personally condemning the FD 85mm - I was just wondering what the contributing factors may be in its percieved inferiority to the EF version. Perhaps its just a function of reputation with not much in the way of actual reasons?
Don,
Thanks for the canonmuseum address - but I am familiar with it. What I was really after is some "critique", as frankly, the actual technical specs don't tell me enough to judge a lens. What I mean is, nothing jumps out at me with a "ah! that's why!" (I am not nearly well-versed enough in lens design) - I was more looking to hear some "user testimony". Sorry if I didn't make myself clear enough.

Gosh, I have no idea. Back in my youth, the Canon and Nikkor 85 were simply seen as fine, premium lenses. So to, all the other makers ! As to why a particular lens gets a bad rap, or a mixed, defies understanding. Short of rounding up a large sample and shooting some film, the best things I can think of is to find some evidence of it being a poor design, or assuming it maybe wasn't so bad !
In the early '70s I sometimes got to assist a wonderful photographer ( I think my only skill was being able to find good places for dinner ) and he was a passionate Canon shooter. Hated Nikon. And he had the 2 good reasons I think one could use to make a rational choice between the two back then.
First, he was left eyed and he invariably stuck his thumb in his right eye whenever he used a Nikon f2. No problem with the layout of a Canon F1.
Second, he shot Leica as well. The Nikon aperture scales and shutter speed ran in opposite directions than the Leica, but Canon were the same.
That's it. Most pros made the choice on similar basis, but too many photographers sought some mystical reason for one or the other brand, and justified their choices however they could. At one time or another, I've heard every good lens described as a loser.
As for the 2 versions of the Canon FD, and the EF, evolution, I'm sure it was something like this:
Version 1, the big pretty 1974 version was probably an update of the FL lens, evolved from the R lens before it. I would expect the FD 85/1.8 to display every good lens trait today.
Version 2, the new FD lens of 1979, was basically the same lens in a smaller package. I would expect new glass availability may have made it possible to make the lens a little smaller.
EF, a 1992 redesign probably necessary to allow for the internal focus for the EOS system, and as good a time as any to improve the lens as they could. It was far more complex than the prior lens, but Canon had learned a few things since making their first SLR 85mm in 1961 !
