I have a 28-90 USM kit lens and an 80-200 f4.5-5.6 both with bad aperture motors (what are the chances) anyway, I know nobody is going to buy these things and they are not worth fixing, they do work when shot wide open though. Aside from flipping the lens around what kind of effects can you make with a lens? These things are pretty much F***ed and I figured I would make a use for them instead of just tossing them. I shoot just about any kind of film you could fit into a 35mm camera so I am open to all suggestions, effects, whatever. My Canon EF bodies are as follows: Digital Rebel XTi, Elan 7Ne and an EOS 650, neat little camera, was going to flip it but decided to keep it as a backup. No issues with the bodies at all, except the Digital Rebel uses a crop sensor smaller than the 35mm 24 x 36mm format, if that means anything.
