ZOOM LENS AND IMAGING APPARATUS

摘要

A zoom lens consists of, in order from the object side, a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, a fourth lens group having a negative refractive power, a fifth lens group having a positive refractive power, and a sixth lens group having a positive refractive power, wherein magnification change is effected by changing all distances between adjacent lens groups. The first lens group is fixed relative to the image plane during magnification change, and the second lens group is moved from the object side toward the image side during magnification change from the wide-angle end to the telephoto end. The sixth lens group includes a positive lens and a negative lens.
