Claim Text:
1. An optical image capturing system comprising five lens elements, 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 with negative refractive power, wherein both of an object-side surface and an image-side surface of the second lens element are aspheric; a third lens element, wherein both of an object-side surface and an image-side surface of the third lens element are aspheric; a fourth lens element having a concave image-side surface, wherein an object-side surface and the image-side surface of the fourth lens element are aspheric; and a fifth lens element 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 the image-side surface thereof; wherein there is a total of five lens elements in the optical image capturing system, and an Abbe number of the second lens element is V2, an Abbe number of the third lens element is V3, an Abbe number of the fourth lens element is V4, and the following relationship is satisfied:
