PHOTOGRAPHING LENS ASSEMBLY

摘要

A photographing lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element, the third lens element and the fourth lens element have refractive power. The fifth lens element with negative refractive power has a convex object-side surface and a concave image-side surface, wherein the surfaces thereof are aspheric, and at least one of the surfaces thereof has at least one inflection point thereon. The sixth lens element with negative refractive power has a convex object-side surface and a concave image-side surface, wherein the surfaces thereof are aspheric, and at least one of the surfaces thereof has at least one inflection point.

1. A photographing lens assembly comprising, in order from an object side to an image side:
a first lens element having positive refractive power; second lens element having negative refractive power; a third lens element having a concave image-side surface; a fourth lens element having positive refractive power; a fifth lens element with negative refractive power having a concave image-side surface, wherein an 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 having a convex object-side surface, wherein the object-side surface and an 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, 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 is a single and non-cemented lens element, an axial distance between the first lens element and the second lens element is smaller than an axial distance between the second lens element and the third lens element.
