The Rodenstock 28mm f/4.5 HR Digaron-S Lens is a wide angle large format lens. The lens is specifically designed for use with digital backs which require a smaller image circle with extreme resolution, color correction, and maximum performance at a large aperture. The lens utilizes every technological possibility to get as close as possible to the absolute limits of diffraction- determined resolution, even accounting for the properties and thickness of a CCD's protective glass. With the HR Digaron-S, you can use digital backs with a pixel pitch as small as 5ยต. This lens is recommended for digital backs with 33 x 44mm maximum image area. This HR Digaron-S is delivered in a standard type Copal #0 shutter.

The open aperture is free of vignetting and can be used as a working aperture and excellent imaging performance at working apertures from 5.6 to 8. To avoid blurring and color fringing caused by the sensor protection glass, the calculation of the optical design includes a 2 mm thick sensor glass and perfect symmetric reproduction due to special adjustment of the optical elements. Thanks to the retro focus design of the wide-angle lenses there is no additional light fall-off and no color fringing on the sensors with micro lenses due to extremely oblique light incidence.

  • Resolution up to 100 line pairs/mm, pixel size up to 5 micrometer
