Claim:
1. An optical image capturing system, in order along an optical axis from an object side to an image side, comprising: a first lens having negative refractive power; a second lens having refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having refractive power; and an image plane; wherein the optical image capturing system consists of the five lenses with refractive power; at least two of the lenses from the first lens to the fifth lens each has at least an inflection point on at least a surface thereof; at least one of the lenses from the second lens to the fifth lens has positive refractive power; the fifth lens has an object-side surface, which faces the object side, and an image-side surface, which faces the image side, and both the object-side surface and the image-side surface of the fifth lens are aspheric surfaces; wherein the optical image capturing system satisfies: where f is a focal length of the optical image capturing system; HEP is an entrance pupil diameter of the optical image capturing system; HOS is a distance in parallel with the optical axis from an object-side surface of the first lens to the image plane; HIF is a distance perpendicular to the optical axis measured from the optical axis to any one of the inflection points on any one of the surfaces having at least an inflection point; InTL is a distance in parallel with the optical axis between an object-side surface, which faces the object side, of the first lens and the image-side surface of the fifth lens.
