The successor of the 1600F was the 1000F (1953–1957). The 1000F was named after its reduced shortest shutter speed of 1/1000 s. The 1000F has a different shutter mechanism and proved to be more reliable and robust than its predecessor. During production of the 1600F, Carl Zeiss in Oberkochen had become a supplier of lenses for the 1600F/1000F cameras. Zeiss supplied the lenses Distagon 5.6/60 mm, Tessar 2.8/80 mm, Sonnar 3.5/135, Sonnar 4.0/250 and Sonnar 5.6/250 mm. Towards the end of the 1000 F production period a Dallmeyer 5.6/508 mm lens made by Cook and Perkins, England, was also available, but did not fully cover the full film format.
