GERMANY - JUNE 18: The East German Zeiss Ikon company introduced the Contax S camera in 1949. It was a 35mm single lens reflex (SLR) camera and was the first SLR to incorporate a pentaprism. It is generally regarded as being the father of all modern 35mm SLR cameras, including this later Contax model. (Photo by SSPL/Getty Images)
