ABSTRACT:
In a zoom lens system dividable into a zooming lens component which varies the magnification without moving the image plane and a relay lens component, at least a part of the relay lens component is made to have no power so that the axial movement thereof may not vary the focal length of the zoom lens system and is moved along the optical axis in association with the zooming lens component to compensate the fluctuation of aberration caused by the movement of the zooming lens component.
