If anyone is interested I would like to trade my Canon FD 24mm f/2.8 S.S.C. lens for a Minolta Rokkor 24mm or an Olympus OM Zuiko 24mm lens. The lens is in good working condition. It's not perfect, there is a little wear and there are probably cleaning marks on the glass and dust inside the lens. The common things you find with old lenses. Otherwise it is in good working condition. It doesn't have any issues that will affect image quality. The lens includes the front and rear caps and a case.
