The Agfa Karat came in two main designs, a viewfinder version with a distinct rounded oval body followed by rangefinders with a more contemporary design.
They were all characterised by a collapsible lens base on struts that would pop out at the push of a button. Initially the Karats used Rapid (or Karat) cassettes instead of the regular 35mm
film rolls. While the actual film was the same, in the Karats the film was pushed from one cassette into another. The advantage was that one could not
accidentally destroy all images by opening the back of the camera, but the number of photos per cassette was limited to only 12. From the Karat 36 onwards the Karats used regular 35mm film rolls.
