Optical image capturing system

An optical image capturing system comprising five lens elements with refractive power, in order from an object side to an image side:

• a first lens element with positive refractive power having a convex object-side surface;
• a second lens element with negative refractive power having a concave image-side surface;
• a third lens element having negative refractive power;
• a fourth lens element with refractive power having a concave image-side surface, wherein an object-side surface and the image-side surface of the fourth lens element are aspheric;
• and
• a fifth lens element with refractive power having a concave image-side surface, wherein an object-side surface and the image-side surface of the fifth lens element are aspheric, and the fifth lens element has at least one inflection point on the image-side surface thereof;
• wherein the optical image capturing system has a total of five lens elements with refractive power;
• and
• the optical image capturing system further comprising a stop, wherein the axial distance between the object-side surface of the first lens element and the image-side surface of the fifth lens element is Td, an effective diameter of the stop is AD, and the following relationship is satisfied:
• 1.2<Td/AD<2.0;
• wherein a focal length of the optical image capturing system is f, a curvature radius of an object-side surface of the third lens element is R5, a curvature radius of an image-side surface of the third lens element is R6, and the following relationship is satisfied:
• f/|R5|+f/|R6|<2.5.
