A Schneider telephoto for Kodak Retina — vintage German optics for the Retina reflex system.
The Schneider Retina Tele Xenar 135mm f/4 is a telephoto prime from Schneider-Kreuznach produced specifically for the Kodak Retina Reflex SLR cameras, which used a proprietary interchangeable lens system. Schneider supplied Retina-mount optics as Kodak's optical partner.
The lens delivers 135mm at f/4 maximum aperture with Kodak Retina Reflex bayonet coupling, manual focus and aperture operation, and Schneider optical quality. The Retina lens system used a unique coupling arrangement where the aperture and focus controls on the camera body connect to the lens mechanically.
The Kodak Retina Reflex cameras with Schneider interchangeable lenses represent a high point of German-American optical and camera manufacturing cooperation in the late 1950s and early 1960s. The Retina system's proprietary coupling means these lenses are functionally limited to compatible Retina Reflex bodies and are primarily of collector interest.
Inspect element condition for haze, fungal spotting, and coating integrity. Test aperture blade operation. Verify Retina Reflex bayonet coupling mechanism, which incorporates aperture coupling levers — check these for clean operation. Collector condition and complete set with body increases value significantly.
