IMAGING LENS AND IMAGING APPARATUS EQUIPPED WITH THE IMAGING LENS |
| 摘要 |
An imaging lens is constituted essentially by six lenses, including: a first lens having a positive refractive power and a convex surface toward the object side; a second lens having a negative refractive power and a concave surface toward the object side; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a positive refractive power; and a sixth lens having a negative refractive power, provided in this order from the object side. The imaging lens satisfies a predetermined conditional formula. |

1. An imaging lens consisting essentially of six lenses, including:
a first lens having a positive refractive power and a convex surface toward the object side; a second lens having a negative refractive power and a concave surface toward the object side; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a positive refractive power; and a sixth lens having a negative refractive power, provided in this order from the object side; the imaging lens satisfying the following conditional formula:
2.4<f3/f1<4.6 (1) wherein f1 is the focal length of the first lens, and f3 is the focal length of the third lens. |
