<p>[Problem] To reduce total length and increase resolution in an imaging lens. [Solution] This imaging lens is substantially formed from five lenses comprising, in order from the object side: a first lens (L1) with an aspherical surface that has positive power and a convex surface facing the object side; a second lens (L2) with an aspherical surface that has negative power and a concave surface facing the image side; a third lens (L3) with an aspherical surface that has positive power; a fourth lens (L4) with an aspherical surface that has negative power; and a fifth lens (L5) with an aspherical surface that has a convex surface facing the image side and is a meniscus lens that has negative power. This imaging lens also satisfies prescribed conditions.</p> |
