Abstract:
1. An image pickup lens composed of five lenses for a solid imaging element, comprising, in order from an object side to an image side, a first lens having a positive refractive power with a convex surface facing the object side, and a second lens having a negative refractive power with a concave surface facing the image side; wherein the first lens and the second lens satisfy following conditional expressions (1), (2) and (3); where ν1 represents an Abbe number of the first lens, and ν wherein the image pickup lens further comprises a third lens having a positive refractive power with a convex surface facing the object side near an optical axis, a fourth lens having both sides formed as aspheric surfaces and having a negative refractive power with a concave surface facing the image side near the optical axis, and a fifth lens having both sides formed as aspheric surfaces and having a positive refractive power with a concave surface facing the image side near the optical axis.
