The Certina was an attempt to create a solid user-friendly beginner's camera. Thus it was constructed with a focusable lens, a big optical viewfinder and a film advance lever. It had a flash-synchronized single-speed shutter. Possible aperture settings were 11, 8, M and B. Distance setting was eased by symbols.

With the aid of the 4x4 mask the Certo Certina can also be used to take 16 smaller pictures on 120 film. On the inside of the removable back there is a switch with which you are able to select one of the two red windows showing the frame numbers on the backing paper of the 120 film.
