Claim:
1. An optical image lens system comprising, in order from an object side to an image side: a first lens element; a second lens element having positive refractive power; a third lens element with positive refractive power having a convex image-side surface; a fourth lens element having negative refractive power; a fifth lens element with positive refractive power having a convex 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 a sixth lens element with negative refractive power having a concave image-side surface, wherein at least one of an object-side surface and the image-side surface of the sixth lens element is aspheric, and the image-side surface of the sixth lens element has at least one inflection point thereon; wherein the optical image lens system has a total of six lens elements and excludes any lens element other than the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element, and there is a gap between every two lens elements the of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element that are adjacent to each other.
