I thank all of you for the informative replys. I am on vacation right now, and my two F-1Ns and A-1 are seeing heavy use. This "all Canon" excursion has been quite enjoyable. It is the first time out for my 55/1.2 (non-asph). What a tank of a lens.
I have that lens on my FT and man what a workout. The heaviest combo that I have, except for my Mamiya but thats a different story there.
