Abstract

An imaging lens consists essentially of, in order from the object side, a first lens group having a positive refractive power, a stop, and a second lens group having a positive refractive power. The first lens group includes, in order from the object side, two successive positive lenses, and a negative lens having a concave surface toward the image side. The second lens group includes, in order from the object side, a lens having at least one aspheric surface, and a three-lens cemented lens. The three-lens cemented lens has a positive refractive power, and is formed by cementing three lenses consisting of, in order from the object side, a positive lens having a convex surface toward the image side, a negative lens, and a positive lens.
