Rodenstock photo optics for professional studio and laboratory photography could gain a high brand awareness. The “photokina” 2008 delivers the ideal platform to present for the first time novelties of Rodenstock lens systems which are optimised to the needs of the professional digital photograpy. These new lens systems offer unique advantages for the photographer:

• Larger image circle diameter for larger camera movements
• Long back focal length for a higher camera mobility and a better shutter-handling
• Minimised vignetting for sensors with micro lenses due to retro focus design.

HR Digaron-S
The new Rodenstock HR Digaron-S lenses (former name: Apo-Sironar digital HR) with a 70 mm image circle (80 mm for a  focal lengths of 180 mm) for sensor sizes from 24x36 mm up to 33x44 mm provide excellent sharpness and brilliance already from open aperture (f/4 to f/5.6). For reduced camera movement they are also recommended for sensor sizes up to 37x49 mm and without any camera movement even for sensor sizes up to 36x56 mm or 40x54 mm.

HR Digaron-W
The lens series  HR Digaron-W with an image circle from 90 mm to 125 mm is the first choice for large sensors from 37x49 mm up to 36x56 mm or 40x54 mm and for technical cameras, if parallel lens shift and lens swing and tilt require large camera movement. Currently this new series comprises the focal lengths 40, 70 and 90 mm. In spring 2009 it will be supplemented by a 50 mm lens, and further lenses will follow in the near future.

For an optimum performance of the highest-resolution sensors with up to 60 megapixels 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.
