Rodenstock HR Digaron-W 40mm
The lens series HR Digaron-W with an image circle from 90 mm to 125 mm is the first choice for large sensors from 37x49mm up to 36x56mm or 40x54mm and for technical cameras, if parallel lens shift and lens swing and tilt require large camera movement. 
For an optimum performance of the highest-resolution sensors with 80 megapixels and more and a pixel pitch down to 6 µm, the optical design of both series HR Digaron-S and HR Digaron-W includes the thickness of the sensor glass plate.
