An optical image lens system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element has positive refractive power. The third lens element has positive refractive power. The fourth lens element has refractive power. The fifth lens element with positive refractive power has a convex image-side surface, wherein at least one surface of the fifth lens element is aspheric. The sixth lens element with negative refractive power has a concave image-side surface, wherein at least one surface of the sixth lens element is aspheric, and the sixth lens element has at least one inflection point on the image-side surface thereof. |
