Claim:
1. An optical image capturing system, in order from an object side to an image side comprising: a first lens with positive refractive power; a second lens with negative refractive power; a third lens with positive refractive power; a fourth lens with positive refractive power; a fifth lens with positive refractive power; a sixth lens with negative refractive power, and at least one of an object-side surface and an image-side surface thereof having at least one inflection point; and an image-plane; wherein the optical image capturing system has six lenses having refractive power, at least one of the second lens to the fifth lens has positive refractive power, an object-side surface and an image-side surface of the first lens are aspheric, and both an object-side surface and an image-side surface of the sixth lens are aspheric, focal lengths from the first lens to the sixth lens are respectively f1, f2, f3, f4, f5 and f6, focal length of the optical image capturing system is f, an entrance pupil diameter of the optical image capturing system is HEP, a half of the maximal view angle of the optical image capturing system is HAF, a distance from the object-side surface of the first lens to the image-plane is HOS, and the following conditions are satisfied: 0≦|f/f1|≦2; 1.2≦f/HEP≦2.8; 0.4≦|tan(HAF)|≦1.5; and 1.3≦HOS/f≦1.7.
