ABSTRACT:
A compact self-blimped motion picture camera is achieved by mounting all drive train components on a mounting frame which together with a truncated conical lens support floats within the camera body. The lens support includes a forward annular lens mount and a generally cylindrical section the rear end of which is affixed to the mounting frame. The lens support is truncated in a 45.degree. plane that intersects the cylinder periphery just rearward of the lens mount and intersects the lens support rear end plane in a line that crosses the cylindrical axis. A rotating shutter and mirror assembly includes a sector-shaped mirror that rotates in a plane immediately behind the lens support truncation plane. Noise is minimized by using only belt and pulley drive components and only sleeve bearings.
