Patent ID: 8705181

Claim:
An 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 with negative refractive power; a third lens element with positive refractive power; a fourth lens element with negative refractive power having a concave object-side surface and a convex image-side surface, wherein at least one of the object-side surface and the image-side surface of the fourth lens element is aspheric; and a fifth lens element with refractive power having a concave image-side surface, wherein at least one of an object-side surface and the image-side surface of the fifth lens element is aspheric, and the fifth lens element has at least one inflection point on the image-side surface thereof; wherein the first through fifth lens elements are five independent and non-cemented lens elements, a maximum image height of the image capturing system is ImgH, an axial distance between the object-side surface of the first lens element and an image plane is TTL, a focal length of the image capturing system is f, and the following relationship is satisfied: 2.8 mm<( f /Img H )× TTL< 4.6 mm.
