Rodenstock know that only a first class enlarging lens guarantees developing success. Their German engineers combine the latest in computer design with superior mechanical craftsmanship. No need to look at technical curves - you can see the Rodenstock difference in every picture. They will repay you with higher resolution, colour fidelity, outstanding field flatness, contrast, and uniform illumination.

The universal lens Rogonar-S has a relatively simple optical design and so a very attractive price. But the very high performance capability of this lens make it ideal for the high requirements of demanding amateurs or professional developing labs. The main application area of the Rogonar-S is enlargement in the scale range required for photographs in the standard formats. In this range the lens with 4 elements in 3 groups provides high-quality results with only low light fall-off to the picture margin.

The recommended scale range can also offer some interesting possibilities for cropped enlargements.

Stopping down by 2 to 3 stops is recommended for optimal results.

It is equipped with a click-stop diaphragm which can be disabled on the models from 50 mm to 105 mm focal length for stepless control. All models from a focal length of 50 mm have an illuminated aperture display and are equipped with a practical pre-set aperture.
