An image stabilization apparatus comprising: an image stabilization unit that performs image stabilization by changing a crop position at which part of image is cropped from an image obtained by photoelectric conversion of an optical image formed through a detachable lens unit by an image sensor based on a vibration amount detected by a vibration detection unit; a control unit that controls the image stabilization unit so as to shift the crop position by a predetermined swing back amount toward a center of the image; and a determination unit that determines whether or not zooming is performed based on focal lengths obtained from the lens unit at a predetermined time interval, wherein the control unit increases the swing back amount in a case where zooming is performed than in a case where zooming is not performed.
