Abstract
A lens apparatus includes; a magnification-varying lens unit, which moves in an optical axis direction during varying magnification, an image stabilization lens unit movable in a direction perpendicular to an optical axis; an image stabilization driving unit for driving the image stabilization lens unit, and an image stabilization controller for controlling the driving of the image stabilization lens unit by the image stabilization driving unit, in which the image stabilization controller controls the image stabilization driving unit to move the image stabilization lens unit so as to reduce a positional deviation of an object image formed at one predetermined point on an image plane, the positional deviation being caused by a movement of the magnification-varying lens unit.
