Abstract
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 negative (−) refractive power, wherein the imaging lens meets a conditional expression of −0.5<f/f3<0 and −0.5<f/f4<0, where f is an entire focus distance of the imaging lens, f3 is a focus distance of the third lens, and f4 is a focus distance of the fourth lens.
