Patent ID: 8395852

Claim:
An optical imaging lens assembly comprising five lens elements with refractive power, 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 with negative refractive power; a third lens element with negative refractive power; a fourth lens element with negative refractive power, and at least one of the object-side and image-side surfaces thereof being aspheric; and a fifth lens element having a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric, and the fifth lens element is made of plastic; wherein a focal length of the second lens element is f 2 , a focal length of the third lens element is f 3 , and they satisfy the relation: 0< f 2/ f 3<1.7.
