A motion-picture camera adapted for use on aircraft or the like where extreme forces are likely to occur, and in which a rapid exchange mechanism is effected by a two-piece construction with the film gate and associated film drive mechanism decouplable from the main body of the camera, and in which the film drive mechanism operates with an eccentric drive for providing stop and go motion through a zero clearance gate, the improvements consisting of an improved adjustable zero clearance gate, guides for handling the film through the film gate, and improvements in the two-piece construction including a novel latch mechanism capable of providing a rapid exchange, yet which also positively provides for accurate placement of the film gate in exact focus position.
