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 having a negative refractive power with both surfaces formed from aspheric surface, a fourth lens of a meniscus shape having a positive refractive power with a convex surface facing the image side, and a fifth lens of a meniscus shape having a negative refractive power with a concave surface facing the image side, wherein the curvature radius of the fourth lens satisfies conditional expression (13) below: 1.4
