Abstract: A motor driven zooming apparatus including a zoom lens, a driver for moving the zoom lens, and an extremity setting and storing device for storing data for restricting a zooming range of the zoom lens. A driver controller is provided for controlling the driver within the stored zooming range.

Abstract: A device for driving a lens including one or more lens groups displaceable in a direction along the optical axis by an electric drive unit. A memory unit is provided for storing a position of the lens group, and a controller for displacing one or more lens groups to the position stored in the memory unit by the electric drive unit.

Abstract: An automatic focusing camera including a control mechanism by which one of a plurality of automatic focusing modes is automatically selected in accordance with a photographing mode. The view finder of the camera is provided with a plurality of distance measuring zones, and distances of objects corresponding thereto are measured, respectively, to enable an output of distance measuring data. The automatic focusing modes are set for a plurality of the distance measuring zones, to thereby focus the photographing lens on one or more objects corresponding to the distance measuring zones. The control unit, based on lens information of the photographing lens and the distance measuring data, calculates a depth of field in accordance with the selected automatic focusing mode, and determines whether or not the object distance is within the required depth of field, to thereby cause the photographing lens to be moved into the required depth of field.

Abstract: A camera having a mid-exposure zooming function, including a zoom motor driving a zoom lens, a trigger switch initiating mid-exposure zooming, and a mid-exposure zooming execution mechanism for initiating the driving of the zoom motor based on the operation of the trigger switch for initiating exposure.

Abstract: A data imprinting device for a camera is provided which imprints symbolic data on a part of a photographing film. The data imprinting device comprises an object luminance photometric sensor for detecting luminance of an object in the vicinity of a symbolic data imprinting area, and a light emitting means including a light source for imprinting symbolic data in a photographing film. The brightness of the light source is controllable. In addition the device comprises a control means for controlling the brightness of the light source in the light emitting means according to the luminance of the object in the vicinity of the symbolic data imprinting area which is detected by the object luminance photometric sensor. In a second embodiment, the quantity of light emitted by the printing section is controlled according to the relationship between the detected luminance of the symbolic data imprinting area and the detected luminance of the areas other than the symbolic data imprinting area.
