Rodenstock Eurygon 35mm f4 brand_Schneider-Kreuznach The Leitz Visoflex II isThe Rodenstock Eurygon 35mm f4 lens is designed for use on an enlarger or on bellows. So while it has a Leica thread mount, you cant just mount it directly to your camera and expect to get a useful result: everything will be out of focus, and theres no way to focus it. So please: enlarger or bellows. In excellent condition, with clean glass and minor wear on the diaphragm blades that will not affect function.
