The Contarex is a single-lens reflex camera that Contax released after the war with great anticipation. The lenses of the Contarex, designed and manufactured by Zeiss Ikon with great prestige, all produce surprisingly excellent images. The Distagon 35mm f4 is also a wide-angle lens that provides sharp images from the wide-open aperture, with a minimum focusing distance of 38cm. This is the later model with a black lens barrel. The exterior has no noticeable large scratches or dents. The operation of both the aperture and focus rings is smooth. The focus is particularly smooth. Optically, there is no mold, haze, or noticeable scratches. It is clear and crisp. Overall, I think it can be considered a good product. Adapters are sold, so it can be used widely.
