All Schneider Apo-Digitar lenses are characterized by the highest resolution minimal distortion and a minimized lateral chromatic aberration. They are optimally suited for current high-end digital camera backs and have generous adjustment paths on the specialized camera.
This 180mm F-5.6 APO lens offers a relatively longer focal length suitable for portraits (as compared to a lens designed for a film view camera). It has a Schneider electronic shutter which offers extremely precise vibration-free exposures.
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. コパル/Schneider APO-DIGITAR 180mm f5.6 Lens in Copal #0 Shutter #03-1002944 03-1002944
