Claim 0:
1. 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 object-side surface of the second 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 and comprises at least one convex shape in an off-axis region thereof;
wherein focal lengths of the third lens element and the fourth lens element have different signs;
wherein an Abbe number of the first lens element is V1, an Abbe number of the second lens element is V2, an Abbe number of the fifth lens element is V5, a maximum image height of the image capturing optical lens system is ImgH, an axial distance between the object-side surface of the first lens element and an image plane is TTL, and the following relationships are satisfied:

0.6<(V2+V5)/V1<1.0; and

TTL/ImgH≤1.70.
