Patent ID: 8780466

Claim:
An optical image capturing system comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface and a concave image-side surface; a second lens element having refractive power; a third lens element having positive refractive power; a fourth lens element with negative refractive power having a concave object-side surface and a convex image-side surface, wherein the object-side surface and the image-side surface of the fourth lens element are aspheric; and a fifth lens element with refractive power having a concave image-side surface, wherein an object-side surface and the image-side surface of the fifth lens element are aspheric, and the fifth lens element has at least one inflection point on the image-side surface thereof; wherein each of the first through fifth lens elements is a single and non-cemented lens element, a focal length of the first lens element is f 1 , a focal length of the second lens element is f 2 , a focal length of the third lens element is f 3 , a focal length of the fourth lens element is f 4 , a focal length of the optical image capturing system is f, a curvature radius of the object-side surface of the fourth lens element is R 7 , and the following relationships are satisfied: 0 <|f 3 /f 1 |+|f 4 /f 2|<1.0; and −1.0 <R 7 /f< 0.
