The Rogonar forms a solid basis for the "first steps" in the amateur's home lab. This lens is already a standard feature of many low-price enlarging units. With 3 single elements, it has a relatively simple optical design. But when used for a smaller scale range of about 2x to 8x and a working aperture of f/11, it still offers good results. The large aperture for a 3 element lens ensures simple and precise focusing and provides a bright image for composition and cropping of the picture. The Rogonar is available with the standard focal length of 50 mm. It has a click-stop diaphragm and an illuminated f-number scale. 105 mm f/5.6 Lens
