A zoom lens having five lens groups arranged in succession. The zoom lens
is configured such that when zooming from a short focal length end toward
a long focal length end, the second lens group lens moves toward the
third lens group and the fourth lens group moves toward a side of the
third lens group, and the fifth lens group corrects the zooming and a
shift in a position of an imaging plane of the zoom lens caused by
movement of the third lens group and the fourth lens group.
