FD lenses are mechanical. EF lenses are electronic. They will not interchange.

canon F1N (new) with AE viewfinder. I think the problem is stuck aperture blades. the disassembly vids on youtube look doable. and even if I screw it up, I can buy another lens for under $50.

Worth a try to fix for $50.
