An automatic focus control apparatus for a camera lens which includes a fixed and a movable optical system, each adapted to form an image of an object to be photographed on a respective photosensitive means. The movable optical system includes a rotatable mirror movable successively in opposite directions, in the first direction at a high rate of speed, and in the second direction at a low rate of speed simultaneously with lens adjustment. Signal processing means compares the signals provided by the photosensitive means and stops the lens and operates a camera shutter during movement of the mirror in the second direction when a maximum or minimum output signal compares with a selected maximum or minimum output signal generated during movement of the mirror in the first direction.

Camera having an automatic focus control apparatus

A camera containing a movable automatic dimmer strobo, which camera, during ordinary photographing operation, sets the iris diameter by way of an automatic exposure control device and, during the flash photographing operation, effects the photographing with a particular iris diameter. Said camera has an automatic dimmer strobo which is so contained as to undergo displacement with respect to the camera body, a film-sensitivity changing ring, and an iris ring that can engage with said film-sensitivity changing ring. Said camera is characterized in that the displacement action of said automatic dimmer strobo is interlocked to the operation which changes the state in which the iris diameter is set by displacing the iris ring to a position corresponding to a turning angle which is set for the ring for changing the film sensitivity, and the iris information is transmitted to the iris device by way of the iris diameter set portion that is provided on said iris ring.

Camera containing a movable automatic dimmer strobo

A camera having a flash mounted thereon is provided wherein the flash is movable with respect to the optical axis of the camera to avoid red eye. When flash must be used, the flash may be raised and one or more pins are provided to automatically disengage the aperture control mechanism from an automatic exposure meter system and engage it with the focusing ring of the camera to automatically adjust aperture as a function of lens to object distance.
