Patent ID: 8432622

Claim:
An image capturing lens system comprising, in order from an object side to an image side: a first lens element with negative refractive power having a convex object-side surface and a concave image-side surface; a second lens element with positive refractive power having a concave object-side surface and a convex image-side surface; a third lens element with negative refractive power made of plastic material, and having a concave image-side surface, wherein an object-side to surface and the image-side surface of the third lens element are aspheric; and a fourth lens element with positive refractive power made of plastic material, wherein an object-side surface and an image-side surface of the fourth lens element are aspheric; wherein the image capturing lens system further comprises a stop between the first lens element and the second lens element, a focal length of the image capturing lens system is f, a curvature radius of the image-side surface of the third lens element is R6, and a curvature radius of the object-side surface of the fourth lens element is R7, the following relationship is satisfied: 0.1<| R 6 −R 7 |/f.
