The Rodenstock 100mm f/4 Apo-Sironar digital HR Lens is a telephoto lens specifically designed for use with large format digital backs which require a smaller image circle with extreme resolution color correction and maximum performance at a large aperture. This lens is recommended for use with backs having a 33 x 44mm maximum image area and provides a view similar to that of a 79mm lens on a 35mm format camera. This HR Digaron-S is delivered in a standard type Copal no. 0 shutter.
In many cases digital photography is superior to conventional photography if the desired end product is a printed image. To achieve this ideal however a much higher demand is made upon the image reproduction quality of the lens. This is because of a digital image chip's smaller area which means finer details in a scene are squeezed into a smaller image recording area as well as their sensitivity to color fringes.
But Rodenstock's digitally-specific lenses such as this HR Digaron-S provide image quality which allows the maximum capacity of a digital back to be realized. The lens utilizes every technological possibility to get as close as possible to the absolute limits of diffraction- determined resolution even accounting for the properties and thickness of a CCD's protective glass. With the HR Digaron-S you can use digital backs with a pixel pitch as small as 5u. This lens is recommended for use only at f/5.6 you should exclusively use your camera's movements to control the depth of field. ローデンシュトック/Rodenstock 100mm f/4 Apo-Sironar Digital HR Lens 150126
