I have a C-MOUNT WOLLENSAK VELOSTIGMAT F1.5 1" LENS. This one is in good used condition - look at the photos. Included is the lens cap illustrated in picture 5. The glass is pretty clean, no fungus or scratches that i can see. The aperture ring works very smoothly, the focus is a bit stiff. It screws nicely into a c-mount adaptor.
NOTE: This is a used lens, and is sold as-is with NO RETURNS! I can not guarantee which 4/3, micro-4/3, other standards it will adapt to.
Price - $225 + shipping.
