Abstract

An exemplary embodiment of the present invention relates to an imaging lens, the imaging lens including, in an ordered way from an object side, a first lens having positive (+) refractive power, a second lens having negative (−) refractive power, a third lens having negative (−) refractive power, a fourth lens having positive (+) refractive power, and a fifth lens having negative (−) refractive power, wherein the imaging lens meets a conditional expression of 0.8<ΣT/((FLD)X2)<1.2, where ΣT is a distance from an object side surface of the first lens to an image-forming surface, and FLD is a distance from an optical axis to a maximum image height.
