Abstract:
An imaging apparatus is able to perform limit control of limiting a drive range of a focus lens and performing control of the focus lens. When first information regarding an end position of the drive range of the focus lens in the limit control is set, a body control unit drives the focus lens from a position set as one end position of the drive range of the focus lens in the limit control on a near side and a far side to one end position of the movable range of the focus lens on a near side and a far side, and then stores information corresponding to a drive amount during the drive as the first information.
