Patent ID: 8879169

Claim:
An image capturing lens system, in order from an object side to an image side comprising three non-cemented lens elements with refractive power: a first lens element with positive refractive power having a convex object-side surface, and both the object-side and image-side surfaces being aspheric; a plastic second lens element with negative refractive power having a concave object-side surface and a convex image-side surface, and both the object-side and image-side surfaces being aspheric; and a plastic third lens element with refractive power having a convex object-side surface and a concave image-side surface, and both the object-side and image-side surfaces being aspheric; wherein the shape of the image-side surface of the third lens element changes from concave at the paraxial region thereof to convex while away from the paraxial region; wherein the image capturing lens system comprises a stop positioned between an imaged object and the image-side surface of the first lens element; wherein a total axial distance of the air intervals between the object-side surface of the first lens element and an image plane is ΣAT, an axial distance between the object-side surface of the first lens element and the image plane is TL, an axial distance between the stop and the image-side surface of the first lens element is SR2, a central thickness of the first lens element is CT1, and they satisfy the following relations: 0.10 mm<Σ AT< 0.65 mm; 0.10 <ΣAT/TL< 0.35; and 0.65 <SR 2 /CT 1<1.50.
