Abstract:
To provide an image pickup lens with a five-lens configuration in which aberrations are corrected favorably despite its compactness. An image pickup lens 10 includes a first lens L1 having a positive refractive power and having a convex face directed to an object side, a second lens L2 of a meniscus shape having a negative refractive power and having a concave face directed to an image side, a third lens L3 having a positive refractive power, a fourth lens L4 having a positive refractive power and having a convex face directed to the image side, and a fifth lens L5 having a negative refractive power and having a concave face directed to the image side, in this order from the object side. Here, the focal length of the fifth lens, the focal length of the entire system of the image pickup lens, and an air separation on an optical axis between the fourth lens and the fifth lens satisfy predetermined conditions.
