Claim 10:
11. An image capturing optical lens system comprising six lens elements, the six lens elements being, 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;
wherein each of the six lens elements has an object-side surface facing towards the object side and an image-side surface facing towards the image side;
wherein the first lens element has positive refractive power; the third lens element has positive refractive power; the sixth lens element has positive refractive power; the object-side surface of the second lens element is convex in a paraxial region thereof; the object-side surface of the third lens element is convex in a paraxial region thereof; the object-side surface of the sixth lens element is convex in a paraxial region thereof; the image-side surface of the sixth lens element is concave in a paraxial region thereof; both of the object-side surface and the image-side surface of the fifth lens element are aspheric;
wherein there is an air gap between each of adjacent lens elements of the six lens elements; an Abbe number of the fifth lens element is V5, an Abbe number of the sixth lens element is V6, and the following relationship is satisfied:

0.20<V5/V6<0.70.
