Abstract:
The zoom lens includes, as lens groups, in order from the object side, only 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 stop is disposed between a lens surface closest to the image side in the second lens group and a lens surface closest to the object side in the fourth lens group. During zooming, at least the first lens group, the second lens group, the third lens group, and the fourth lens group move. The first lens group consists of a negative lens, a positive lens, and a positive lens in order from the object side. The zoom lens satisfies predetermined conditional expressions.
