Cambo Rodenstock 40mm f/4.0 HR-W Copal #0 Lens

The Rodenstock 40mm f/4 HR Digaron-W Lens is a wide angle lens specifically designed for use with 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 40 x 54mm maximum image area, and provides a view similar to that of a 26mm lens on a 35mm format camera. This HR Digaron-W is delivered in a standard type Copal #0 shutter.

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 5 micrometer.

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-W, you can use digital backs with a pixel pitch as small as 5micro.

Despite this lens' short focal length, it provides an adequate 69.5mmm flange focal length with 25.1mm of space between the rear of the barrel and the image receiving area, permitting its unrestricted use on nearly any camera which accepts a medium format digital back.
