Berning Robot Robot I

Produced from 1934 to 1938 by Berning Robot of Dresden, Germany, the Robot I holds a significant place as one of the pioneering 35mm still cameras utilizing a unique rotary shutter mechanism. Designed by Heber Klein, it featured a compact, robust metal body primarily aimed at professional photographers, particularly those needing rapid shutter speeds for capturing fast action like sports or photojournalism. The camera's most defining innovation was its focal-plane shutter, which achieved speeds up to 1/500 second through a rotating slit, making it notably faster than many contemporaries. This design also allowed the Robot I to double as a 16mm movie camera (using 17.5mm film) by simply attaching an external magazine, highlighting its versatility. Its finder was simple and external, requiring separate rangefinder focusing.

The Robot I was a purpose-built tool for the working professional. Its key features included a fixed 50mm f/3.5 lens (early versions) or interchangeable lenses on later models, coupled with a quick-action wind lever and a film capacity of 24 or 36 exposures on standard 135 cartridges. While not as ergonomically refined as later designs, its sturdy construction and high shutter speeds earned it a reputation for reliability and speed in demanding environments. It filled a niche between the expensive Leicas and simpler amateur folders, representing a significant step in applying the emerging 35mm format for dynamic, high-speed photography.
