ZOOM LENS, AND VIDEO CAMERA AND DIGITAL STILL CAMERA USING THE ZOOM LENS

摘要

Provided with a shake correction function, and further, it is possible to prevent deterioration of the chromatic aberration at the time of shake correction, it is possible to realize a zoom lens size, weight, power consumption saving. From the object side toward the image plane side arranged in this order, positive, negative, positive, has a positive refractive power, a second zoom lens of four group configuration for performing variable magnification, focus adjustment in the fourth lens group in the lens group. And the second lens group is a concave meniscus lens arranged in this order toward the image side from the object side, and the negative lens, biconvex lens, made of a concave lens, and further, comprises an aspheric surface of the at least one surface . The third lens group is movable in a direction perpendicular to the optical axis to the joint surface, and a cemented lens including a convex surface facing toward the object, correcting the variation of the image at the time of hand movement.
