Chronology of cameras Certo 

This camera is a double (Doppel) format, meaning that on a 120 film, it is possible to obtain negatives of either 6 x 9 (8 frames) or 4.5 x 6 (16 frames). Of course, there is a reducing mask to be put in place or retracted. The originality of this camera is that the mask is mounted on a pivot, and a turn of the key is enough to put it in place or not. The key is visible on the side of the camera. The lens is a doublet with an aperture of f/11, without focusing. On the front face, under the lens, a slider allows the insertion or not of a portrait lens attachment.
