| 发明名称 | Imaging lens and imaging apparatus equipped with the imaging lens | ||
| 摘要 | An imaging lens is constituted 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 convex surface toward the object side; a third lens having a positive refractive power; a fourth lens having a positive refractive power; a fifth lens having a positive refractive power and a convex surface toward the object side; 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. | ||

| 主权项 | 1. An imaging lens consisting 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 convex surface toward the object side; a third lens having a positive refractive power; a fourth lens having a positive refractive power; a fifth lens having a positive refractive power and a convex surface toward the object side; and a sixth lens having a negative refractive power, provided in this order from the object side; the imaging lens satisfying the following conditional formulae: f23/f<−2.5 (1);2<f34/f<4.5 (2) wherein f23 is the combined focal length of the second lens and the third lens, f34 is the combined focal length of the third lens and the fourth lens, and f is the focal length of the entire system. | ||
