One lens I got from Alex along with the Canon F-1n is the legendary FD 35 f2 with the chrome nose complete with the radioactive rare earth glass element. All I can say is wow, the results are mind blowing and the 35 f2 lens weighs a ton especially mated with the Canon F-1n body. I pack a two lens set up if I'm in the city the 35 lens along with the 100 f2.8 telephoto. Anything more, my briefcase gets heavy.
