Rodenstock HR Digaron-S 28mm

Rodenstock HR Digaron-S 28mm, provide excellent sharpness and brilliance from open aperture (f/4 to f/5.6).  Rodenstock HR Digaron-S 28mmEven at the image corners sharpness is high enough to utilize the resolution power of the highest-performance sensors with up to 60 megapixels and a pixel pitch of only 6 µm. An image quality almost impossible up to now is realized due to perfect correction of curvature of field, integration of the 2mm thick sensor cover glass into the optical calculation and excellent correction of chromatic aberration in order to avoid color fringes.
