A zoom lens including a varifocal lens unit having a plurality of movable lens groups, and a prism disposed on an image side of the varifocal lens unit. The prism has an incident plane on which a light flux from the varifocal lens unit enters, and an exit plane from which the light flux is emitted toward an image plane, and is configured such that the incident plane or the exit plane or both planes can be inclined with respect to an optical axis, whereby a field of view is shifted by a predetermined amount by inclining the plane.
