Schneider- Kreuznach Xenon 50mm f1.9 lens (Exakta mount) READ DESCRIPTION.

This lens is for parts or repair only. Turning the aperture ring does not move the aperture blades, and as such the lens is stuck at f11 or f16. Technically, this lens is still usable at those apertures, but it's only fair to mark this as for parts or repair only. If you know how to repair the aperture mechanism, this vintage bokeh-monster can be yours for a steal!

The glass and cosmetics are beautiful, however. Very clear front and rear elements, with no fungus or haze. A good cleaning is recommended, however.

No dents to the lens casing, very few scuffs in general. Some wear to the paint at the base of the lens.
