Abstract:
1. An optical image capturing lens system, in order from an object side to an image side comprising five lens elements with refractive power: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power; a third lens element with positive refractive power having a convex image-side surface; a fourth lens element with refractive power having a concave object-side surface and a convex image-side surface; and a fifth lens element with positive refractive power having a convex object-side surface at a paraxial region, both of the object-side surface and an image-side surface of the fifth lens element being aspheric, and at least one inflection point is formed on at least one of the object-side surface and the image-side surface thereof; wherein lens elements with refractive power in the optical image capturing lens system are the first lens element, the second lens element, the third lens element, the fourth lens element, and the fifth lens element; wherein a focal length of the optical image capturing lens system is f, a focal length of the fifth lens element is f
