Alpa 40mm HR Digaron-W Rodenstock 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.
