Abstract:
1. 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 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 convex object-side surface and a concave image-side surface, wherein the 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, each of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element a single and non-cemented lens element, a focal length of the fifth lens element is f
