This is a Schneider 28mm f/2.8 Wide Angle APO Digitar Lens in a Rollei #0 Electronic Shutter. Large format cameras and lenses designed for use with digital camera backs are the ultimate combination in digital photography. Although Photoshop can maneuver (interpolate) pixels to simulate some perspective shifts in doing so it diminishes the quality of the image. A view camera is still necessary for perspective shape and focus control.
Newer lenses for large format digital cameras are slightly smaller in size and shorter in focal length than lenses designed for 4x5 or 8x10 film. Digital sensor chips are usually smaller than their film format counterparts. Several 35mm Style Digital SLR's are an exception. The format conversion factor for a 4x5 lens for film to a 4x5 Digital Lens is 1.39. ローライ/Schneider DIGITAR 28mm f/2.8 Lens in Rollei Electronic #0 Shutter #03027631 03-027631
