This is a high quality fairly rare 90mm lens for Leica screw mount. It would be an excellent addition to a classic L39 kit or adapted to mirrorless.
This one has a few condition issues. There is a slight haze on an inner element along with a few fine cleaning marks on the front and rear elements that may soften your images slightly when shooting in harsh conditions. Otherwise the lens is clean and works well, there is no fungus or any other problems. The focus is smooth and the aperture is dry and snappy.
A front cap is included.
