When Zeiss Ikon was founded in 1926 by a merger of camera makers Ernemann's renowned cine camera product line was continued. Astoundingly the amateur cine camera branch was continued after 1945 in the postwar state-owned socialist East German VEB Zeiss Ikon. One fine example is the sturdy handsome nicely designed spring-motor-driven viewfinder movie camera Pentacon AK8 for "double 8" (or "regular 8") cine film which was 16mm film on metal spools. Only one half of the film stripe was exposed. The daylight loading film spool had be turned and reloaded after reaching 7.5 metres to expose the second half of the film stripe. The camera took spools with 7.5 metres film. A small window in the back showed the used film length in metres. A tab in the reverse Galilean viewfinder indicated film end. The lens was a non-focusable 2.8/10 Zeiss Jena Triotar which could be stopped down from f2.8 to f11. With aperture f2.8 depth of field was from 2.1 metres to infinity, with f11 from 77cm to infinity. The shutter had a fixed speed of 1/32 sec. at 16 frames per second, and selectable exposure modes were continous (D), shutter release controlled (L) and single shot (E).
