Claim:
1. An optical image capturing system, from an object side to an image side, comprising: a first lens element with a positive 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; a sixth lens element with a negative refractive power and at least one of the image-side and the object-side surfaces of the sixth lens element having at least one inflection point; and an image plane; wherein the optical image capturing system comprises six lens elements with refractive powers, at least one of the second through fifth lens elements has a positive refractive power, the object-side surface and the image-side surface of the first lens element are aspheric, 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, half of a maximal view angle of the optical image capturing system is HAF, a distance from the object-side surface of the first lens element to the image plane is HOS, and the following relation is satisfied: 0≦|f/f1|≦2, 1.2≦f/HEP≦2.8, 0.4≦|tan(HAF)|≦1.5, and 0.5≦HOS/f≦2.5.
