Patent ID: 8760776

Claim:
An optical image capturing lens assembly comprising four lens elements, 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 plastic second lens element with negative refractive power and a concave image-side surface, wherein at least one of an object-side surface and the image-side surface thereof is aspheric; a plastic third lens element with positive refractive power having a concave object-side surface and a convex image-side surface, the object-side and image-side surfaces thereof being aspheric; and a plastic fourth lens element with negative refractive power, an object-side surface and an image-side surface thereof being aspheric, the image-side surface being concave, at least one inflection point being formed on at least one of the object-side and image-side surfaces thereof; the optical image capturing lens assembly further comprises a stop; wherein an axial distance between the object-side surface of the first lens element and the image-side surface of the fourth lens element is Td, a curvature radius of the object-side surface of the first lens element is R 1 , a curvature radius of an image-side surface of the first lens element is R 2 , an axial distance between the stop and the image-side surface of the fourth lens element is SD, and they satisfy the following relations: 1.25 mm<Td<1.75 mm; −4.0<(R 1 +R 2 )/(R 1 −R 2 )<−1.3; and 0.85<SD/Td<1.1.
