Bolex H-16 Reflex

Bolex H-16 Reflex, a wind-up movie camera. The first wind-up movie cameras came on the market around 1930, replacing hand-cranked cameras. Their introduction revolutionized filmmaking; it was now much easier to maintain a correct speed, and for the first time, it was possible to adjust the aperture and focus. Spring-wound cameras had a spring that was wound with a crank, which powered the mechanism. More advanced cameras had the feature that they would not change speed throughout the entire wind-up, and the motor would stop instead of slowing down. One wind-up was not enough for long, or at most about a minute in smaller models of cameras.
