Patent ID: 8867149

Claim:
A photographing lens assembly 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 having refractive power; a third lens element having refractive power; a fourth lens element having positive refractive power; a fifth lens element with negative refractive power having a convex object-side surface and a concave image-side surface, wherein the object-side surface and the image-side surface of the fifth lens element are aspheric, and the fifth lens element has at least one inflection point on at least one of the object-side surface and the image-side surface thereof; and a sixth lens element with negative refractive power having a concave image-side surface, wherein an object-side surface and the image-side surface of the sixth lens element are aspheric, and the sixth lens element has at least one inflection point on at least one of the object-side surface and the image-side surface thereof; wherein the photographing lens assembly has a total of six lens elements with refractive power, a focal length of the fifth lens element is f5, a focal length of the sixth lens element is f6, an axial distance between the object-side surface of the first lens element and the image-side surface of the sixth lens element is TD, a maximum image height of the photographing lens assembly is Y, an axial distance between the image-side surface of the sixth lens element and an image plane is BL, and the following relationships are satisfied: 0 <f 6 /f 5<1.2; and ( TD/Y )+( BL/Y )<1.65.
