| 主权项 | 1. An imaging lens, the imaging lens comprising, in an ordered way from an object side: a first movable lens having a positive (+) refractive power; a second lens having a negative (−) refractive power; a third lens having a positive (+) refractive power; a fourth lens having a positive (+) refractive power; and a fifth lens having a negative (−) refractive power, wherein the imaging lens meets a conditional expression of 0.8<f3/f1<1.0, where f1 and f3 are focus distances (focal lengths) of the first and third lenses, respectively. | ||
