PROBLEM TO BE SOLVED: To provide an optical image capturing lens set which reduces total length of an image capturing lens and yet maintains good optical performance.SOLUTION: An optical image capturing lens set comprises; a first lens element 10 having positive refractive power and a convex surface on the object side; a second lens element 20 having negative refractive power and an image-side surface which is concave near a circumferential edge thereof; a third lens element 30 having an object-side surface which is concave near a circumferential edge thereof; a fourth lens element 40 having positive refractive power, a concave surface on the object side, and a convex surface on the image side; and a fifth lens element 50 having an object-side surface which is convex near an optical axis and an image-side surface which is concave near the optical axis, and being convex near a circumferential edge thereof. |
