Zeiss Ikon is a German company that was formed in 1926 by the merger of four camera makers (Contessa-Nettel, Ernemann, Goerz and Ica), and an infusion of capital by Zeiss[1]. The company formed one part of the Carl Zeiss Foundation, another part being the optical company Carl Zeiss. Logically, most of the Zeiss Ikon cameras were equipped with Carl Zeiss lenses; and the formerly independent companies, in particular Goerz, had to shut down their own lens manufacture.
