Anyone know where I might be able to get an 85mm FD f1.2 L lens repaired? The shutter blades are jamming up and the focus started to drag. This was a beautiful lens. I took it to one repair shop. He opened it up and says the cam that holds the shutters has worn out and needs to be replaced. Unfortunately he cannot locate anywhere that would have parts for it. He has suggested trying to find one on ebay and breaking it open for parts.

Anyone have any ideas on who might be able to fix this?

Thanks!
