Abstract

According to exemplary embodiments of the present invention, an imaging lens includes in an ordered way from an object side, a first lens movable and having positive (+) refractive power, a second lens having negative (-) refractive power, a third lens having positive (+) refractive power, a fourth lens having positive (+) refractive power, and a fifth lens having negative (-) refractive power, wherein, a conditional expression of 0.5 < f1/fz1, f1/fz2, f1/fz3 < 1.5 is satisfied, where focus distances of imaging lens are respectively fz1,fz2 and fz3, and a focus distance of the first lens is f1 at zoom positions 1, 2 and 3.
