Claim Text:
1. An optical image capturing system comprising, in order from an object side to an image side: a first lens element with positive refractive power having an object-side surface being convex at a paraxial region thereof; a second lens element having refractive power; a third lens element having refractive power; a fourth lens element with negative refractive power having an object-side surface being concave at a paraxial region thereof and an image-side surface being convex at a paraxial region thereof; a fifth lens element with positive refractive power having an object-side surface being convex at a paraxial region thereof, wherein the object-side surface and an image-side surface of the fifth lens element are aspheric, and the fifth lens element has at least one inflection point on at least one of the object-side surface and the image-side surface thereof; and a sixth lens element with negative refractive power having an object-side surface being concave at a paraxial region thereof, wherein the object-side surface and an image-side surface of the sixth lens element are aspheric; wherein the optical image capturing system has a total of six lens elements with refractive power, a curvature radius of the object-side surface of the fifth lens element is R9, a curvature radius of the image-side surface of the fifth lens element is R10, a central thickness of the third lens element is CT3, a central thickness of the fourth lens element is CT4, and the following relationships are satisfied:
