System components for macro lenses

Normal lenses used for photography typically produce good imagery in the range of 1:oo to about 1:10. With larger magnifications, the optical performance of these lenses falls off considerably. Even so-called macro lenses, which are corrected for magnifications from 1:oo to 1:2 or 1:1, are an optical compromise.

The Macro System enables the use of Schneider enlarging lenses to capture the highest quality close-up and macro images. These lenses are designed exclusively for close-up scales of about 1:20 to 1:1.

The Macro System provides an uniform interface with 3 lock-screws that engage into a groove. This guarantees a stable and durable connection and makes it possible to use multiple combinations of the individual components. It also permits the reversal of the lenses for magnified images.

Due to the good mechanical stability, the Macro System is also very suitable for industrial use.

Lenses

The optical components of the enlarging lenses are screwed into a compact and robust diaphragm body, which makes it possible to adjust and to lock the aperture and to use accessories such as filters. Because the interface is identical on both sides, the lenses can be reversed for magnifying images. Ten lenses are available:

Lens name	Iris / Focal length	Code-No.
Componon	2.8 / 28	14794
Componon	2.8 / 35	14792
Apo-Componon	2.8 / 40	14798

Componon-S	2.8 / 50	14796

Helical Mounts UNIFOC 12 and UNIFOC 7

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 respectively Unifoc 7 Helical Mount makes this possible.
It is extremely compact with 12 mm respectively 7 mm of displacement.

In the shortest setting, the mechanical length is 17.4 mm with the Unifoc 12 and 20 mm with the Unifoc 7. 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.
