For sale is my Kodak Retina IIIS camera system, serial EK803878 with a Schneider-Kreuznach 50mm 2.8 lens, serial 6185539. Schneider-Kreuznach Retina Curtagon 28mm f4, serial 9924369. Schneider-Kreuznach Tele-Xenar 135mm f4 telephoto, serial 6890631. The Retina IIIS is a rangefinder but these same lenses also work on Retina Reflex S, III, and IV slrs. I believe it's the only camera system that an slr and a rangefinder share the same lenses. The lenses also have a Hasselblad style moving depth of field indicators as you change the aperture settings. Changing aperture is done by turning the the serrated wheel on the bottom of the camera (see photo 1 and 3). Also like all Retina cameras, the film counter counts down from either 24 or 36 to 1. When changing lenses the the frame lines automatically change to match the angle of view of the lens. The widest setting is for the 35mm wide angle lens, Kodak made a slip on viewfinder for the 28mm. I never bought the add on viewfinder but if you use the left and right edges within the camera viefinder you pretty much have it. Actually, you have a little more than the viewfinder indicates since I have checked by putting the lens on a Retina S slr. The IIIS was cla'd by Retina expert Chris Sherlock, http://rawhiti.tripod.com/, in March of 2011. The silk rope which connects the lens coupling to the meter is original and in great shape. Chris would have replaced it with a nylon one if it needed it. I would rate the camera in excellent shape. The selenium meter works, and it is quite accurate with bright light. The chrome has only minor scuffs, the leatherette is in fantastic shape and not peeling at all anywhere. The only thing missing is a leather camera case which did not come with it when I purchased it. The 135mm and the 28mm come with their own plastic protective case. The 28mm has a metal built in lens shade (picture 4). The outside edge of the shade is 58mm in diameter and despite being slightly bent it is easy to screw in a 58mm filter. I have a metal lens shade made for this lens (photo 5), I will include it in the sale at no extra charge. Sorry for the low quality of that photo, took it with my cell. I don't have a digital camera. The 135mm has its original box, instructions and mail order receipt from Wall Street Camera Exchange in New York from May 26, 1961 for $69.50! (Shipping and handling:$1.50). Also included is a 29.5 to 37mm step up ring for the Schneider-Kreuznach 50mm 2.8 so you can use 37mm filters or attach a larger step up ring like a 37mm to 46mm to use larger filters, which is what I did. All the glass is clear and fungus free and the self timer works. $350 via Paypal or postal money order includes shipping in the United States, Paypal for international orders.
