Rodenstock 120mm f/5.6 APO Macro-Sironar Digital Lens with eShutter

This line of lenses provides the photographer with even larger image circles for digital photos with adjustable professional cameras. They allow taking two and more laterally shifted overlapping photos for stitching as well as taking large-format photos with scanner backs. Focal lengths from 35 mm mean that real wide-angle shots are possible, even with the standard area sensor sizes, while still allowing large movements.

The gap between the focal lengths 55 mm and 105 mm can be closed with the HR Digaron-W 70 mm and 90 mm lenses with image circles of 100 mm and 120 mm diameter respectively.Due to the small formats on the one hand (which are sensitive to higher diffraction!) and the high illumination requirements of the CCD image sensor on the other, digital photography does not allow the lenses to be stopped down as much as in conventional large-format photography.

As a result, these lenses have been optimized for a working aperture of 8 to 11. Because both the surface of the area sensors and the area scanned by the CCD line sensors have greater planarity than conventional roll and sheet films, special attention was given to the correction of the curvature of field.

The freedom from distortion, which is so important for product and building pho-tography, and the uniformity of illumination are also excellent.The Apo-Macro-Sironar digital provides a special macro lens at the same superb performance level of the Rodenstock Apo-Sironar digital series for high-resolution digital photos at repro-duction scales from 1:5 to 2:1.
