Disclosed is a zoom lens that forms an optical image of an object on a light receiving surface of an imaging element converting the optical image to an electrical signal, having the diagonal length of 2Y max, is constituted by a positive first group, a negative second group, a negative third group, an aperture, and a rear group having positive power as a whole, in order from an object side, and satisfies a conditional expression 1.5<frw/Ymax<2.1 (frw denotes the combined focal length of the rear group on a wide end, and Ymax denotes the maximum image height). |
