Abstract
An image stabilization apparatus which is capable of properly correcting for image blurring while at the same time obtaining correct focus evaluation values. Based on a detected shake, a vibration isolation lens is moved in a direction different from a direction of an optical axis of a shooting optical system. While a focus lens is being moved in the direction of the optical axis, focus evaluation values are obtained based on an image pickup signal obtained by taking an image of a subject. A method to control the focus lens is determined according to whether or not the focus lens is being moved, and with the determined method, movement of the focus lens in the direction of the optical axis is controlled based on an amount by which the vibration isolation lens has moved.
