Abstract: The present invention relates to an imaging lens and the present invention comprises: a first lens having a positive (+) refractive power; a second lens having a negative (−) refractive power; an iris (aperture); a third lens having a negative (−) refractive power; a fourth lens having a negative (−) refractive power; and a fifth lens having a positive (+) refractive power, wherein the first lens, the second lens, the third lens, the fourth lens and the fifth lens can be sequentially arranged along an optical axis from a subject side. Since the length of an optical system is shorter than a focal distance, the present invention can be effectively used for an imaging lens of an optical system requiring a low telephoto ratio.
