The Rodenstock HR Digaron-S Copal 0 28mm f/4.5 Lens with Lens Board from Arca-Swiss is developed for special applications with extremely high resolution CCD chip backs with pixel sizes smaller than 10 to 5μm. The lens provides optimum sharpness for high resolution line and area sensors to benefit from this technology. The f/4.5 aperture of this lens reduces color noise in shadows. The lens is well suited for smaller sensors up to 33 x 44mm. 

With high-end optics, the lens gets as close as possible to the absolute physical limit of diffraction-determined resolution. The optimized resolving power and lateral chromatic aberration ensure that the resulting lack of sharpness or the color fringes do not amount to any more than a tiny fraction of the pixel size (which can no longer be resolved). As a result, even when the digital photos taken with the lens are enlarged to a maximum on the screen, absolutely no color fringes are visible, unless color fringes are added by the pixel structure of the sensor's Bayer filter or due to interpolation.

Note: The lens is recommended for use with sensor formats larger than approximately 37 x 49mm only if no larger camera movements are needed.

Lens Board opening of 1.37" (34.80mm) and thickness of 0.05 to 0.15" (1.50 to 4.00mm)
