To achieve the miniaturization, high image quality, and high zoom ratio of a zoom lens.
In the zoom lens configuration having five groups of positive, negative, positive, positive and positive refractive powers, the fifth lens group GR5 is configured of, in order from an object side to an image side, a fixed group GR5-1 having a negative refractive power and being fixed, and a movable group GR5-2 having a positive refractive power and being movable in a direction substantially orthogonal to the optical axis. The image formed on an image surface is movable in a direction substantially orthogonal to the optical axis by moving the movable group of the fifth lens group in the direction substantially orthogonal to the optical axis. The zoom lens is configured to satisfy the following conditional expressions (1) and (2): 0.6<¾f51/f52¾<1.0 (1); and 0.2
