Motor drives for compact and amateur cameras
  • Motor drives for compact and amateur cameras wind slowly—shot-to-shot intervals of approximately a second are commonplace. Professional grade cameras are faster, with speeds up to 10 frames per second (fps). The first 35 mm SLR to achieve such a shooting speed was Nikon's F High Speed Motor Drive camera, first developed for the 1971 Chicago Photo Expo with 7 fps. To enable this speed and allow the photographer to more easily track the moving subject, this camera used a fixed, semi-transparent pellicle mirror instead of a moving mirror. Later special Canon models used similar mechanisms to achieve such speeds, while cameras with moving mirrors reached approximately 5 frames per second by the 1980s. Today, the fastest professional models from Canon and Nikon achieve approximately 10 frames per second with a moving mirror.
