Abstract

A zoom lens includes a positive first lens group, a negative second lens group, a positive third lens group, and a subsequent group consisting of plural lens groups in order from an object side. In a case of zooming, an interval with an adjacent lens group is changed. The third lens group includes two uncemented positive lenses consecutively arranged in order from a side closest to the object side to an image side. A lens group closest to the image side in the subsequent group consists of a negative meniscus lens having a concave surface toward the object side and a positive lens having a convex surface toward the object side in order from the object side to the image side.
