<p>Provided is a six-layer configuration image capture lens that is compact and has adequate light at F2 or less, and wherein all aberrations are effectually corrected. In order from the object side, the image capture lens is configured of a first lens having a positive refraction and with a convex face oriented toward the object side; a second lens having a negative refraction and with a concave face oriented toward the imaging side; a third lens having either a positive or a negative refraction; a fourth lens having a positive refraction; a fifth lens having a positive refraction and with a convex face oriented toward the imaging side; and a sixth lens having a negative refraction and with a concave face oriented toward the imaging side. The imaging side face of the sixth lens further comprises an aspherical face shape, has an inflection point in a location other than a point of intersection with the optical axis, and satisfies the following formulae: ? d1 > 50, and ? d2 = 30, wherein ? d1 is the Abbe's number of the first lens, and ? d2 is the Abbe's number of the second lens.</p> |
