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 for the Kodak Retina Reflex camera system. Schneider-Kreuznach produced the lenses for Kodak's Retina cameras — bringing German optical excellence to the Retina range. The Tele Xenar 135mm provides telephoto reach on the Retina interchangeable lens system.
Optical performance is good — Schneider quality for Kodak. The f/4 is modest but typical for 135mm telephotos of the era. Sharpness is respectable. Schneider's multi-coating provides good contrast. A well-made vintage telephoto from a respected German optical manufacturer. Build quality is excellent precision metal.
Kodak Retina mount — proprietary and very limited. Weight varies. Build quality is outstanding Schneider/Kodak precision. The Retina mount severely limits compatibility. Film era — 35mm format. Adapters for modern cameras are extremely rare for the Retina mount.
Very cheap if found. Only for Retina system collectors and Schneider optical enthusiasts. The optical quality is genuine Schneider but the mount limits all practical use. A piece of German-American optical heritage with no modern application.
