1919- Cinegraphe-Bol - Birth of 35mm motion picture camera for amateur movie making. The camera was also capable of taking and projecting both still and moving pictures, enlarging negatives and printing movie positives on standard 35 film. Hand cranked with optional clockwork motor that could be fitted.
1927- Invents and releases the Bolex amateur movie cameras.
1928- Development and production of the first 35mm high class reflex range finder combination camera, known today as the “Swiss Alpa”.
1929- Bol Auto Cine Camera B- Similar to the first model with a few modifications. The camera could hold 30m (100ft) daylight loading spools in comparison to the prior models 15m daylight spools. To allow for the larger spools the body gained two bulges which made the camera easier to hold. The body shape was used in 1935’s Bolex H16 design. Projectors for the camera were introduced. The second projector model took both 9.5mm and 16mm film by using interchangeable parts. It is thought to be the first amateur dual-gauge projector ever produced.
