Goerz Manufoc-Tenax (Manufok in German) is a series of folding bed plate medium format to large format film camera, manufactured by Optische Anstalt C.P. Goerz AG. Friedenau, Berlin, Germany and produced between c.1908-c.1926.[1]
Many variations were made over the production duration. "Manufoc" stands for manual focusing to differantiate it from Autofoc-Tenax which was auto-focusing meaning self-erecting.
