Abstract

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).
