Abstract
An image stabilization optical system for use in the variable magnification optical system having a first lens group followed rearwardly by a zoom section comprising a plurality of lens groups is disclosed, wherein as at least one lens group in the zoom section is made to be a compensating lens group, the optical action of each lens group is properly specified so that if the tilting of the optical system is the same, the amount of compensation movement of the compensating lens group becomes always the same regardless of the image magnification varying position.
