Claim Text:
1. An optical image capturing system, in order from an object side to an image side, comprising: a first lens element with a refractive power; a second lens element with a refractive power; a third lens element with a refractive power; a fourth lens element with a refractive power; a fifth lens element with a refractive power; and a sixth lens element with a negative refractive power having a concave image-side surface adjacent to an optical axis, and at least one of the image-side surface and the object-side surface has at least one inflection point; wherein the optical image capturing system comprises the six lens elements with refractive powers, at least one of the first through fifth lens elements has a positive refractive power, the object-side surface and the image-side surface of the first lens element and the sixth lens element are aspheric, correspondingly, focal lengths of the first through sixth lens elements are f1, f2, f3, f4, f5, and f6, respectively, a focal length of the optical image capturing system is f, an entrance pupil diameter of the optical image capturing system is HEP, TV distortion for image formation in the optical image capturing system is TDT, and the following relation is satisfied:
