When a target position of the focusing lens, which is required to keep the image in focus after the zoom lens is moved, is located on a near side, i.e., on an imaging plane side, of a threshold position determined based on the obtained near limit position, focus control is performed to move the focusing lens and thereby focus. When the target position of the focusing lens is not located on the near side but is located on a subject side of the threshold position, on the other hand, focus control is performed to move the zoom lens to a wider position and subsequently move the focusing lens to focus the image.
