Chronology of cameras Certo 

Traduction de PY Petit.

This camera is a Doppel (double) format: it can take 6x9cm (8 shots) or 4.5x6cm (16 shots) on the same film width. Of course, there is a frame mask that the user has to put in or remove, depending on the format he/she wishes to use. The distinctive element of this camera is that the frame mask is hinged and that a single stroke on a key will cause the frame to move in its place. This key is located on the side of the camera.

The lens has two elements and its aperture is 1:11.
