Koch created the first Sinar camera in 1948 and – following his philosophy that pros should be able to rely on better equipment than amateurs – developed it steadily further by applying the latest technical refinements. Important milestones were the introduction of a universal shutter for all lenses, selective exposure metering at the film plane and the simplification of camera settings. After Koch turned the responsibility for the family enterprise over to the next generation in 1982, the company continued to follow his guidelines by developing modular professional camera systems that enable pros to enter the digital age. Every Sinar camera can be equipped with the latest digital backs.
