I'm thinking of buying a Super Canonflex R 100 2.0 lens, and will need a body to shoot it with. I'm pretty sure I can use it on a FL body like a FTb, but what about on something like an AE1? I don't mind if it only works in stop down mode. Anyone have any experience w/ the Canonflex R lenses? I've never even seen one, but I understand the 100 2.0 is a heck of a good lens. Thanks.
