Claim Text:
1. An optical image capturing system comprising, in order from an object side to an image side: a first lens element having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof; a second lens element having positive refractive power; a third lens element with negative refractive power having an image-side surface being concave in a paraxial region thereof; a fourth lens element with positive refractive power having an image-side surface being convex in a paraxial region thereof; and a fifth lens element with negative refractive power having an image-side surface being concave in a paraxial region thereof, wherein both of an object-side surface and the image-side surface of the fifth lens element are aspheric, and the image-side surface of the fifth lens element has at least one inflection point; wherein the optical image capturing system has a total of five lens elements, an Abbe number of the fourth lens element is V
