About us

sondor was founded in 1952 by Willy Hungerbuehler. Early customers were the Swiss and German TV stations. sondor soon established its name as innovative manufacturer of 16mm and 35mm magnetic film equipment and invented world-wide standards such as the bi-phase interlocking signal. Today, the company manufactures film transports and a wide range of accessories used in post studios and preview theatres, many of them built to order.
