Abstract
An automatic focusing camera is operated between daylight and flash modes automatically responsively to ambient light photosensings. The lens is operable between a near-focus setting and a far-focus setting, taking the far-focus setting automatically in the daylight mode. In flash mode the aperture is automatically set to its maximum value, whereas in daylight mode the aperture is automatically set to one of at least two reduced aperture settings. The largest aperture setting in daylight mode is the hyperfocal aperture setting corresponding to the far-focus lens setting. A further reduction in aperture below the hyperfocal value is governed by a filmspeed entry system and ambient light sensings. The changeover threshold between daylight and flash mode is also governed by the filmspeed entry system.
