A zoom lens includes, sequentially from an object side, a positive first lens group, a negative second lens group, a positive third lens group, and a positive rear lens group. During zooming from a wide angle position to a telephoto position, an interval between the first lens group and the second lens group increases, and an interval between the second lens group and the third lens group decreases. The rear lens group includes a positive first sub-group, a negative second sub-group, and a positive third sub-group, and focusing is performed by moving the second sub-group toward an image surface side. The zoom lens satisfies the following conditions: 0.2
