Chronology of cameras Cornu 

Traduction de Sylvain Halgand

Week-end Bob uses the same body as Reyna Cross and Sem-Kim. Two things dissociate it these other cameras. Most visible is the gilding of the buttons, the red of marking and the bluish lens. The second, much less visible is the fact that this camera is with interchangeable lens ( Leica screw mount). There existed around this camera an optical system, certainly limited, but which allowed the use of a small telephoto, to make macrophotography etc…
There is no aperture setting. The weather indications make it possible to regulate the shutter speed. There is no setting of distance, but the lens can draw very slightly forwards decreasing this distance.
Curiously, this camera which is to be regarded as rare comes from the USA.

Mr Jean Marc Guillaume, announces several remark to me concerning “Week End Bob II”, of which it also acquired in the USA.

The characteristics of this model II are apparently on the following points :

1) The frontal plate which is different and mentions “Week end BOB II”, speeds which go from 25 to 200 + B, the reference towards the table which is with the back and of the apertures which spread out from 3,5 to 22.

2) The lens block is always removable, but is equipped with a lens Planyl 50-3,5 and a small lock which is under the lens and allows an angular positioning of the block to release the vision in the viewfinder for example. It is the use which I concluded from it but this gadget remains a little mysterious.

Specified brought by Mr. Arnaud Saudax: The lens was transformed into teleobjective by intercalating three extension tubes and by positioning a divergent lens in front of the lens.
