Patent ID: 8488259

Claim:
An optical image capturing lens 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; a second lens element; a third lens element; a fourth lens element; and a fifth lens element with negative refractive power, at least one of 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 the optical image capturing lens system at least has one front stop and one rear stop; the front stop is positioned between an imaged object and the third lens element; the rear stop is positioned between the third lens element and the fifth lens element; wherein an effective radius of the front stop is YF, a maximum image height on an image plane of the system is ImgH, an effective radius of the rear stop is YR, an axial distance between the object-side surface of the first lens element and the rear stop is DR, and they satisfy the following relations: 0.1< YF /Img H< 0.5; 0.2< YR /Img H< 0.8; and 0.4< DR /Img H< 1.2.
