Abstract:
The zoom lens consists of, in order from an object side: a first lens group that remains stationary during zooming and has a positive refractive power; at least two movable lens groups that are moved during zooming; and a final lens group that remains stationary during zooming and has a positive refractive power. The final lens group consists of, in order from the object side, a front group and a rear group. The front group has, successively in order from a position closest to the object side, two or less positive lenses and one first front group negative lens, and a second front group negative lens that is different from the first front group negative lens at a position closest to an image side and is concave toward the image side. An aperture stop is provided between the movable lens group and the first front group negative lens. The rear group consists of a positive lens and a rear group negative meniscus lens that is convex toward the image side. In addition, the zoom lens satisfies predetermined conditional expressions.

Claim (Index 7):
The zoom lens according to  claim 1 ,\n wherein the front group consists of, in order from the object side, a positive lens, a positive lens, the first front group negative lens, a positive lens, a positive lens, and the second front group negative lens.
