<p>The present invention has, in the stated order along the optical axis from the object side, a first lens which has a negative refractive power, a second lens which has a positive refractive power, a third lens which has a positive refractive power, a fourth lens which has a negative refractive power, a fifth lens which has a negative refractive power, and a sixth lens which has a positive refractive power. The present invention satisfies conditional expression (1): 1.52<L3R1/f3…(1), where L3R1 is the radius of curvature of the object-side lens surface of the third lens (L3), and f3 is the focal length of the third lens (L3).</p> |
