For all you film guys out there, I've recently bought a bag full of lenses to improve my FL kit when I shoot miniature format :greenpbl35mm) and I'm particularly happy with this one. FL lenses aren't compatible with any Digi-cam and practically any other SLR because they have an extremely short register and any adaptor would have to be mounted INSIDE the mirror box (not gonna happen), so they've plummeted in price. SO JUICY! I've got a few really nice ones but the one I'm most thrilled with today is the portrait prime I flea-bay'ed for about thirty bucks. It's REALLY nice and sharp. I'd recommend it to anyone. It was Canon's top of the line lenses in that format before they started branding their best "L" and it lasted through three mounts R, FL and FD. FD versions go for a decent price, R-versions aren't compatible with FD bodies (canon ae-1 etc..) but the FL is a sweetheart of a deal.
