A zoom lens includes first, second, third, and fourth lens groups respectively having positive, negative, negative, and positive powers. The first lens group includes an 11 lens group having a negative power, which is fixed during focusing operations, a lens group having a positive power, which moves during focusing operations, and a lens group having a positive power, which is fixed during focusing operations. The 11 lens group includes two negative meniscus lenses having concave surfaces toward an image side, and a cemented lens constituted by a biconcave lens toward an object side and a biconvex lens toward the image side. A distance D4 between the second meniscus lens and the cemented lens and the focal distance f1 of the first lens group satisfy the relationship: 0.60
