Zeiss Ikon Slow-Motion Film Camera, c. 1940

Zeiss Ikon, Dresden. No. W28844, for 16mm film strips on 30-meter daylight spools, with integral spring motor, Zeiss Ikon 1:2.8/50 mm lens in a macro setting mount from infinity to 0.5 m. crop control via an interchangeable Newton viewfinder on the camera housing, electrical functions untested. – In addition: Original labeled transport box. – Note: Due to the high frame rates, a mirror ring is installed instead of a frame switcher, which continuously accompanies the film image on its progress through the camera. When powered by the built-in spring mechanism, 1,000 images per second were possible. When coupled to the attached Zeiss Ikon motor, 3,000 images per second were possible. The necessary stability against the vibrations caused by weapons tests was achieved by an exceptionally heavy wooden tripod. In order to meet the demands of the booming armaments industry, Zeiss Ikon developed this new slow-motion camera to replace the previous 1928 model. A first example was presented at the Leipzig Autumn Fair in 1939 under the motto "A new camera for industry and the Wehrmacht". The number produced is not known. Most of these slow-motion devices were delivered to the Army Research Institutes to document armor-piercing ammunition and other technical processes. In addition, several such cameras are said to have been brought to Peenemünde for documentation of the V1 and V2 rocket projectiles.
