This is an interesting lens with character. Ideal for use on DC if you already have the Contax to M (or similar) adapter. This one is in good condition (USSR standard). Has some light wipe marks on the front and rear surfaces, some dust inside. However, takes good pictures. Please google for more information of this lens.
Also comes with the very rare original plastic case as shown. It fits the lens well as shown. Not the typical one you can find.
