Geiss-America was a company in Chicago that offered accessories for Argus cameras. Starting in 1952 they announced innovative lenses under the Sandmar brand for the Argus C3, whose Cintar normal lens had not outwardly seemed interchangeable. These were manufactured by Enna Werk of Munich, Germany. In 1954, Geiss offered a series of Enna Lithagon lenses for the Argus C4, by means of a proprietary, dealer-installed lensmount modification. Argus answered with its own interchangeable-lens C44, but most consider the Geiss C4 to be the more functional system.

- This was announced and advertised in early 1952; however by 1953, Sandmar wide and tele lenses were selling under Argus's own brand.
