This is a vintage Leitz Summicron 50mm f/2 Dual Range (DR) lens, designed for the Leica M-mount. This specific model, with serial number 1895356, was manufactured in 1961 and is highly sought after by collectors and photographers. Its defining feature is the close-focus mechanism, which allows for a close focusing distance of just 19 inches (0.48 meters). For proper function at these close distances, the lens must be used in conjunction with a pair of close-focusing goggles (not included), which are necessary to correct the rangefinder's view. Renowned for its superb optical performance, this lens delivers exceptional sharpness, contrast, and classic rendering.
