Patent ID: 8149515

Claim:
A zoom lens comprising in order from an object side to an image side: a first lens unit configured to have a positive refractive power; a second lens unit configured to have a negative refractive power; a reflective member configured to bend an optical axis; and subsequent lens units; wherein a distance between the second lens unit and the subsequent lens units is reduced during zooming from a wide-angle end to a telephoto end, wherein one of the subsequent lens units is configured to include, in order from the object side to the image side, a non-shift lens unit that is unmoved during image stabilization, and a shift lens unit that is moved in a direction including a directional component orthogonal to an optical axis direction to change an image-forming position in a direction orthogonal to the optical axis direction during the image stabilization, and wherein the following conditions are satisfied: 1<(1 −βb )β r< 3 0.70 <Lb/Lp< 2.00 where βb and βr respectively represent a lateral magnification of the shift lens unit and a total lateral magnification of all lens units disposed further on the image side than the shift lens unit when the zoom lens is focused on an infinitely distant object at the telephoto end, Lb represents a distance from an image side surface of the reflective member to an object side lens surface of the shift lens unit when the zoom lens is focused on the infinitely distant object at the telephoto end, and Lp represents a thickness of the reflective member on the optical axis.
