ABSTRACT:
A camera has an exposure control unit and a focus control unit. The exposure control unit selectively provides a programmed exposure control mode, where an aperture value and a shutter speed value are automatically set based on a detection by a light metering sensor and an accordance with a preset program, and a manual exposure control mode where at least either of the aperture value and the shutter speed value is set manually. The focus control unit selectively provides an autofocus mode where a focusing is automatically effected based on a detection by a focus sensor and a manual focus mode where the focusing is effected manually. The invention is characterized by a feature which permits a forcible switchover of the focus control mode from the manual to the auto focus mode in response to a switchover of exposure control mode from the manual to the auto exposure mode.
