The Grandagon-N 65mm f/4.5 is a highly corrected wide-angle lens with a 105 degree angle of view. The high maximum aperture of f/4.5 makes adjustments easier, and the working aperture of f/11-16 allows shorter exposure times for outdoor work. The use of an optional Rodenstock center-filter is recommended for critical work. This lens is mounted on a matched focusing mount with a mounting plate specific to the Horseman SW612 and SW612 Pro cameras.
