Gallus Derby-Lux and Aznavour, La Boheme

Gallus Derby-Lux (similar to Gallus Derlux) is based on Foth Derby, a smimple German camera from the 30's. History has forgotten him but he was probably a good man, because he needed to move away from Germany during the darkest times.

Film format, 127, 6 by 3 cm, but it uses only a half, like Canon Demi for example, thus the format is 4 by 3 cm.

Mechanism is simple, shared by many similar cameras, with shutter speeds ranging from 1/25 to 1/500 s.

Viewfinder is a simple telescope, not connected with anything.

There were 3 types of lens available for it:

- Gallix 50mm 1:3.5 three-element focusable lens, made by Gallus itself, the one that I have

- Berthiot Flor f/2.8, never seen one of them of LeBonCoin

- Boyer Saphir f/3.5 or f/2.8, as common as Gallix
