Claim Text:
1. An optical image capturing system, from an object side to an image side, comprising: a first lens element with refractive power; a second lens element with refractive power; a third lens element with refractive power; a fourth lens element with refractive power; a fifth lens element with refractive power; a sixth lens element with refractive power; and an image plane; wherein the optical image capturing system comprises the six lens elements with refractive power, at least one of the first through sixth lens elements has positive refractive power, the object-side surface and the image-side surface of the sixth lens element are aspheric, 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, a distance from the object-side surface of the first lens element to the image plane is HOS, a distance from the object-side surface of the first lens element to the image-side surface of the sixth lens element is InTL, a sum of an absolute value of each distance in parallel with the optical axis from a maximum effective diameter position to an axial point on an object-side surface of each of the sixth lens elements is InRSO, a sum of an absolute value of each distance in parallel with the optical axis from a maximum effective diameter position to an axial point on an image-side surface of each of the sixth lens elements is InRSI, a sum of InRSO and InRSI is Σ|InRS|, and the following relation is satisfied: 1.2≦f/HEP≦6.0, 0.5≦HOS/f≦3.0 and 0<Σ|InRS|/InTL≦5.
