The Beseler HD80mm f4 (AKA Rodenstock Rodagon 80mm f4) is a good quality lens for medium format enlargers. In excellent condition, with clean glass. Attaches to your enlarger lensboard with a standard 39mm thread mount. Includes retaining ring, does not include caps.

Please note: This lens has a standard LTM (39mm) thread mount, but it is not designed to be mounted on LTM cameras. Don’t buy this for your rangefinder, because it will not work at all. It is for enlargers only.
