Schneider-Kreuznach Curtagon f:4 85mm lens that appears to be a DKL mount. This will fit some Kodak Retinas and any other cameras that take a DKL mount lens. Glass looks good, but I can only see so much when the blades are fully open. Some of the glass cannot be seen but I am fairly certain it is good as well. The blades work fine. The metal body is in excellent condition. Also included is the original plastic base [ bubble top is not present ], a Camron K1 2X teleconverter and a clean 52mm HCE UV filter. Very nice looking lens.
