The second lens group is constituted by a bi-convex lens having a positive optical power and a bi-concave power having a negative optical power, which are located in this order from the object side and bonded to each other to constitute a cemented lens. The third lens group is constituted by a bi-convex lens having a positive optical power. The first and fifth lenses are double-aspherical lenses formed from resin and the third and fourth lenses are single-aspherical lenses.
