Patent ID: 8456758

Claim:
An image capturing lens system, in order from an object side to an image side comprising five lens elements with refractive power: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power; a third lens element with both the object-side and image-side surfaces thereof being aspheric; a plastic fourth lens element with both the object-side and image-side surfaces thereof being aspheric; and a plastic fifth lens element having a concave image-side surface, both the object-side and image-side surfaces thereof being aspheric, and at least one inflection point is formed on at least one of the object-side and image-side surfaces thereof; wherein a chief ray angle at one full length of an image height on an image plane from an optical axis is CRA1.0Y, a focal length of the first lens element is f 1 , a focal length of the fifth lens element is f 5 , and they satisfy the following relations: 35 deg< CRA 1.0 Y< 48 deg; and −3.5 <f 1 /f 5<1.5.
