The Canon FD 50 1.8 lenses were basically body caps for years, but now they're expensive. The 50 FL 1.8 lenses are cheaper, but it's been a long time since I used them, and I can't figure out if they're presets?
My AV-1 camera is aperture priority only. It has no DOF preview, and no way to manually stop down a lens. What I want to do is focus wide open, and then stop it down (w/ the front FL lens ring?) and let the camera decide on the shutter speed. Is this how these lenses could be expected to work on an aperture priority camera?
