Claim:
1. An optical image capturing system, from an object side to an image side, comprising: a first lens element with positive refractive power; a second lens element with negative 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 consists of six lens elements with refractive power, at least two lens elements among the first through sixth lens elements respectively have at least one inflection point on at least one surface thereof, at least one of the first through sixth lens elements has positive refractive power, an object-side surface and an image-side surface of the sixth lens element are aspheric, 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 an axial point on an object-side surface of the first lens element to an axial point on the image plane is HOS, thicknesses in parallel with an optical axis of the first through sixth lens elements at height ½ HEP respectively are ETP
