More Info

The Horseman 45mm f/4.5 Apo-Grandagon Lens is a Rodenstock 45mm f/4.5 Apo-Grandagon with a standard Copal #0 shutter, but built into a Horseman-specific helical focusing mount and barrel assembly made to fit upon their SW612/SW612 Professional medium format cameras. Used with a 6x12 film back, this lens produces a 102° x 63° field of view, and upon the 612 cameras the helicoid focusing mount allows a minimum focusing distance of 1.3' (0.4m). A small amount of shift is also permitted.

The 45mm f/4.5 Apo-Grandagon incorporates ED (Extra-low Dispersion) glass, to make truly apochromatic resolution from a wide angle lens possible for the first time. Its large maximum aperture of f/4.5 makes adjustments easier on the ground glass, and the f/11-16 working aperture allows shorter exposure times in outdoor work. The use of the optional #29225 center filter (HOCF67P2.5) is recommended for critical work, especially with transparencies.
