Abstract:
A zoom lens consists of, in order from an object side, a positive first lens group, a negative second lens group, a positive third lens group, a positive fourth lens group, and a positive fifth lens group. During zooming, the first lens group and the fifth lens group are not moved, and the second lens group, the third lens group, and the fourth lens group are moved. The second lens group includes a negative lens closest to the object side. In a case where a focal length of the second lens group is denoted by f2 and a focal length of the negative lens of the second lens group closest to the object side is denoted by f21, the zoom lens satisfies 0.6
