ABSTRACT:
In a camera having a focus detection device which detects a focus state of an object at a plurality of focus detection spots in an imaging area, there are provided an operation portion which selects an arbitrary focus detection spot in the imaging area, and a setting portion which sets the focus detection spot selected by the operation portion as a focus detection spot group. A signal used to set a focus state of the focus detection spot in the thus set group is output by an AF sensor, an arithmetic operation portion detects the focus state of the focus detection spot based on an output from this AF sensor, and a lens drive portion drives a focus optical system to adjust its focus based on a detection result of the focus state obtained by the arithmetic operation portion.
