Abstract
The zoom lens consists of, in order from an object side, a first lens group having a positive power, a second lens group having a negative power, a third lens group having a positive power, a fourth lens group having a negative power, and a fifth lens group having a positive power. An aperture diaphragm is disposed between a surface of the second lens group closest to an image side and a surface of the fourth lens group closest to the object side. The first lens group and the fifth lens group each consist of two or less lenses. A negative meniscus lens, which is convex toward the object side, is disposed to be closest to the object side of the second lens group. A negative meniscus lens, which is convex toward the image side, is disposed to be closest to the image side of the fourth lens group.
