In many areas, digital photography is superior to conventional photography if the desired end-product is a printed image: digital photography is faster, cheaper for very high photo quantities, it makes retouching easier, allows more effective manipulation and, under certain circumstances, has a higher quality. However, it also makes much higher demands on the image reproduction quality of the lenses.

For this reason, Rodenstock has developed lenses for the most demanding quality requirements. They ensure that the substantial investment in the digital camera back and the computer equipment produce both extended technical possibilities and sharper and more brilliant prints.

Apo-Sironar Digital and Apo-Macro-Sironar Digital | Optimised for professional digital photography

This line of lenses provides the photographer with an exhaustive spectrum of focal lengths for digital shots in the very highest imaging quality with adjustable professional cameras. The fine gradation meets the demands of every motif situation and all chip and scanner formats. Focal lengths from 35 mm mean that real wide-angle shots are possible even with the smaller chip sizes while still allowing large movements. All Apo-Sironar digital lenses are characterized by excellent sharpness and brilliance together with total freedom from color fringes in real apo quality.

The Apo-Macro-Sironar digital provides a special lens at the same superb performance level of the Apo-Sironar digital series for high-resolution digital photos at reproduction scales from 1:5 to 2:1.

Apo-Sironar Digital HR | For excellent shots with high resolution chip and scanner backs and very fine pixels

The Rodenstock Apo-Sironar digital HR was developed for special applications with extremely high resolution CCD chip cameras and CCD line scanner cameras with pixel sizes of <10 µm such as can only be realized with smaller digital camera formats.

This lens utilizes every technological possibility to get as close as possible to the absolute limit of diffraction-determined resolution. Among other things, even the optical properties and the thickness of the CCD protective glass were taken into the equation of the optical correction.
