Chronology of cameras Certo  

The Dolly is either a klapp (X-shaped struts) or a folding camera. Both types use 127 film, but the first produces negatives of 3 x 4 cm and inherits the name Dolly 3 x 4, while the second produces larger negatives (4 x 6.5 cm).
Both models coexisted in the 1930s.

Each of the two types is subdivided into two models, each with numerous variants depending on the shutter and lens model:


Non exhaustiv Klapp (Dolly 3 x 4) Folding
Model A Model B 1 Model A Model B2
Vario Compur   Compur Compur    


Radionar
f/2,9
       
Certar
f/4,5
     
Certomat
f/8
           

1 The B model of the klapp has focus adjustment through a radial lever.
2 The B model of the folding camera is hybrid: film and plate.

This version, despite having a Compur shutter, only features a simple frame viewfinder.
