Abstract:
A zoom lens having an image stabilizing function, comprising, from front to rear, a first lens unit of positive refractive power, a second lens unit of negative refractive power and one or more lens units having, overall, a positive refractive power, zooming from a wide-angle end to a telephoto end being performed by axially moving said first lens unit and at least one lens unit of said one or more lens units toward an object side, and the shortest focal length of said zoom lens being shorter than the diagonal length of an image frame, wherein said second lens unit is made to move in directions perpendicular to an optical axis so as to correct shaking of an image occurring when said zoom lens vibrates,wherein said zoom lens satisfies the following condition:0.5<.vertline.f.sub.q /(f.sub.o -e.sub.T).vertline.<1.2where f.sub.o is the focal length of said first lens unit, f.sub.q is the overall focal length for the telephoto end of said one or more lens units, and e.sub.T is the principal point interval between said first lens unit and said second lens unit for the telephoto end.
