Abstract
A controller recognizes the requirement for taking a scenic picture when a scenic picture-taking button is operated to indicate that a scene to be photographed is at infinity rather than at the longest focusable distance of an automatic focusing device, and then sets a taking lens system at an infinity focusing lens position, overriding the automatic focusing device. At the same time, when the scene at infinity is darker than a predetermined brightness level, the controller sets a shutter to open for a predetermined night photography exposure time which is greater than the maximum exposure time that could be set by an automatic exposure control device. When taking a night photograph, light emission from a strobe is prevented.
