Rodenstock Apo-Ronar-CL 30" 760mm f/14 barrel process lens with factory lens caps. The glass is clear with no fungus, haze, fog or scuffs. The aperture ring works smoothly and correctly. The lens is very clean cosmetically. This is a smashing lens. Incredibly sharp and as far as I can see will cover up to 16x20. It is used as an enlarging lens or some people use it as a camera lens. The aperture of f/14 does not seem to be an issue with focusing.
