Hi. Im presenting this specimen. Classic Pentacon 50/1.8 manual lens on m42 mount. Condition: overall very good ( minor scratches on body) Optics : very good condition ( no haze,no fungus, coatings in order) Mechanics: apeture works fine, helicod works with stronger resistance ( its fine with me). Very nice middle-production design.
