Abstract:
An image pickup lens includes a first lens having a positive refractive power with a convex surface facing the object side, a second lens having a negative refractive power with a concave surface facing an image side, a third lens of a meniscus shape having a convex surface facing the object side, a fourth lens of a meniscus shape having a positive refractive power with a convex surface facing the image side, and a fifth lens having a negative refractive power with a concave surface facing the image side, wherein the both surfaces of the fifth lens have an aspherical shape, and the curvature radius of the fourth lens satisfies conditional expression (13) below: 1.4
