Claim Text:
1. An optical image lens system comprising, in order from an object side to an image side: a first lens element having positive refractive power; a second lens element having positive refractive power; a third lens element having refractive power; a fourth lens element having refractive power; a fifth lens element with refractive power having a convex object-side surface, wherein at least one of the object-side surface and an 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 sixth lens element has at least one inflection point on at least one of the object-side surface and the image-side surface thereof; wherein the optical image lens system has a total of six lens elements with refractive power, and 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 of the optical image lens system, there is a space in a paraxial region between every pair of lens elements that are adjacent to each other.
