The very first apparatus associated with the Bolex name was actually a 35mm device.

: It was aimed at the amateur market, but 35mm film proved too expensive for home enthusiasts. This led Bogopolsky to pivot toward the more economical 16mm format, which eventually birthed the iconic Bolex Auto Ciné and the H16 series. Rarity : Today, the 35mm BOL-Cinégraphe

: It was a "reversible" device, designed to serve as a camera, printer, and projector all in one unit.

: In 1923, Ukrainian engineer Jacques Bogopolsky (later Jacques Bolsey) presented the Cinégraphe BOL at the Geneva Fair.
