Abstract

The zoom lens consists of, in order from an object side, a positive first lens group, a negative second lens group, a negative third lens group, and a positive fourth lens group. During zooming from a wide-angle end to a telephoto end, the second lens group moves to an image side, and the third lens group moves to the image side after moving to the object side. The fourth lens group consists of, in order from the object side, a positive fourth A lens group, a negative fourth B lens group moving during image blur correction, a positive fourth C lens group, a fourth D lens group moving during focusing, and a fourth E lens group having a refractive power with a sign different from that of a refractive power of the fourth D lens group.
