Abstract:
1. A single focus optical image capturing system comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; second lens element having negative refractive power; a third lens element having refractive power; a fourth lens element with refractive power having an object-side surface and an image-side surface being 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 at least one of the object-side surface and the image-side surface thereof; wherein a TV distortion for close-up photographing of the single focus optical image capturing system is TVDm, a TV distortion for long distance photographing of the single focus optical image capturing system is TVDi, and the following relationships are satisfied:
