| 摘要 |
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. |
