ABSTRACT:
A multi point focal detection camera is switchable between an automatic mode and a manual mode. An automatic focusing system focuses a movable lens system having a lens on a selected one of multiple focus detection areas in accordance with either focus detection data or a focus detection area selection lever. A CPU enables the selected one of the multiple focus detection areas to be changed to another of the multiple focus detection areas without changing the operation mode. Once the lens system is focused on the selected focus detection area, the selected focus detection area can be changed by displacing the focus detection area selection lever within a predetermined period of time. If the selected focus detection area is changed to another of the multiple focus detection areas, the automatic focusing system focuses the lens system on the new focus detection area.
