Helical Mount

Enlarging lenses have no built-in helicoid, because they are usually focused using a bellows on the enlarger. Therefore, in order to focus an enlarging lens when it is used on a camera, a helical mount is needed. The Unifoc 12 helical mount makes this possible. It is extremely compact with 12mm of displacement

In the shortest setting, the mechanical length is 17.4mm. It comes complete with a focus locking screw.

Focus Mount

Enlarging lenses have no built-in helicoid, because they are usually focused using a bellows on the enlarger. Therefore, in order to focus an enlarging lens when it is used on a camera, a focus mount is needed. The Unifoc 7 mount makes this possible. It is extremely compact with 7mm of displacement.

In the shortest setting, the mechanical length is 20mm. It comes complete with a focus locking screw.

Extension Tubes

Unlike small and medium format photographic lenses, enlarging lenses have no fixed flange-to-image distances. The distance from the lens to the camera is different for each lens with the same imaging dimensions. Cameras differ also in their back focal lengths, which means that the extension length of the lenses on the image side must be adapted to the current image task. This is done with extension tubes, which can be combined in different lengths. They are installed between the lens and the camera.
