Abstract
An imaging device to which a lens device including a focus lens capable of moving in an optical axis direction is detachably attached, includes: an imaging element; a search control unit; an evaluation value calculation unit; a target position determination unit; a focusing control unit; a storage unit; and a lens information acquisition unit, as defined herein, and the search control unit selectively performs one of acceleration and deceleration control such that a movement speed of the focus lens is decelerated after the movement speed is accelerated and constant speed control such that the movement speed of the focus lens is constant by controlling the movement speed based on the evaluation values, based on the lens performance information and the first imaging performance information.
