摘要： Provided from the object side are a first lens group (11) having a positive refracting power and fixed to the image plane, a second lens group (12) having a negative refracting power and a magnification varying action exhibited when moving along the optical axis, a third lens group (13) fixed to the image plane and having a positive refracting power, and a fourth lens group (14) movable along the optical axis so as to maintain the image plane moving with the movements of the second lens group (12) and of the object in a fixed position from a reference plane. Hence the movement of the image due to camera shake is corrected by moving the whole third lens group (13) vertically to the optical axis. The size is reduced and the aberrations are small because the whole groups whose optical performance is united are decentered.

摘要： A first lens group (G1) fixed with respect to the image plane includes a lens (11) having a negative refractive power, a lens (12) having a positive refractive power and a lens (13) having a positive refractive power. A second lens group (G2) has a negative refractive power as a whole, and causes a zooming action when moved along the optical axis. An aperture stop is fixed with respect to the image plane. A third lens group (G3) includes a lens (31) having a negative refractive power and a lens (32) having a positive refractive power, has a positive or negative refractive power as a whole, and is fixed with respect to the direction of the optical axis when zooming and when focusing. A fourth lens group (G4) has a positive refractive power as a whole, and moves along the optical axis such that the image plane, which is displaced by a movement of the second lens group (G2) along the optical axis and by a movement of the object, is maintained at a constant position with respect to a reference plane. Thus, it is possible to realize a compact and high-image quality small zoom lens that is suitable for three-CCDs.
