SOM Berthiot or Berthiot in short was a French optical
company from about the beginning of the XXth century. Very early, it
made the Périgraphe wide angle lenses for large format. These had a very
slow aperture but a huge coverage and some are still in use today. After
World War I, it sold some cameras under their name.
It was one of the most famous French lens makers. After the World War
II, it competed with Angénieux in both still and cine lenses. Berthiot
made a handful of lenses in Leica screw mount and Contax rangefinder
mount. They are very rare and today they can fetch high prices at
collectors auctions.
For the cine lens market, Berthiot launched the Pan-Cinor lenses in 1950
with variable focal length (today called zoom lenses), whereas Angénieux
released its Zoom lenses in 1958. In 1960, Berthiot released the Servo-Cinor
lens for 8mm cameras with a built-in selenium meter driving auto
exposure.
In 1964, SOM Berthiot merged with OPL (the maker of the Foca rangefinder
camera) to become SOPELEM (Société d'Optique Précision ELEctronique et
Mécanique). |
