A zoom lens includes a first lens group having positive refractive power, a second lens group having negative refractive power, a third lens group having positive refractive power, and a fourth lens group having positive refractive power, which are in this order from an object side, and a stop located between a most image-side surface of the second lens group and a most image-side surface of the third lens group. Distances between the lens groups change when magnification is changed from a wide angle end to a telephoto end. The third lens group consists of a positive lens, a cemented lens of a positive lens and a negative lens, a negative meniscus lens with its concave surface facing the object side, and a biconvex lens, which are in this order from the object side. Further, a predetermined conditional formula is satisfied.
