I've got a pair of lenses that I would like to trade. Both are for the Kodak Retina. First one is a Schneider-Kreuznach Retina-Curtagon f:4/28mm with the bubble case. Second one is a Schneider-Kreuznach Retina-Tele-Arton f:4/85mm. It also has the plastic bubble case, but is missing the metal piece to keep the lens securely in place. Both lenses are in good shape with clean glass. I'm open to trades for Exakta lenses, LTM lenses, etc. Who knows! I don't have a Retina Reflex to use these and I need another camera like I need another hole in my head. PM me if you are interested.
