Abstract: A small pocket type camera is provided which includes a plurality of picture-taking lenses and a corresponding plurality of viewfinder lenses. The lens system is arranged so that upon changing the picture-taking lens from one system to another the appropriate viewfinder lens will automatically be moved to the viewfinder optical axis whereby the magnification of the subject to be photographed, as seen by the user through the viewfinder lens, will correspond to the magnification of the subject as recorded on the film through the picture taking lens.

Abstract: A camera including a film advance mechanism having a film advance plunger which is mounted for reciprocal movement from a rest position to a depressed position for operating the film advance mechanism to move film along an exposure plane and coil it about a take up spool. A film metering finger connected to said film advance mechanism and movable from a retracted position on one side of the exposure plane to an extended position traversing the exposure plane. Film is advanced by depressing the plunger. When the metering finger senses a perforation in the film at a predetermined location, movement of the finger disables the film advance mechanism to prevent further film advancement, even though plunger movement may continue. This disabling is accomplished by separating two adjacent and substantially collinear members which connect the plunger to a ratchet drive mechanism that rotates a film take-up spool.
