Abstract

An optical image capturing 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 and a fifth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element has negative refractive power. The third lens element has negative refractive power. The fourth lens element with negative refractive power has a concave object-side surface and a convex image-side surface. The fifth lens element with refractive power has a concave image-side surface, wherein the fifth lens element has at least one inflection point formed on at least one surface thereof. Both of the object-side surface and the image-side surface of the fourth and fifth lens elements are aspheric. The optical image capturing lens assembly has a total of five lens elements with refractive power.

First claim

What is claimed is:

1. An optical image capturing lens assembly comprising, in order from an object side to an image side:
a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof;
a second lens element having negative refractive power;
a third lens element having negative refractive power;
a fourth lens element with negative refractive power having an object-side surface being concave in a paraxial region t…
