Claim 0:
1. An image capturing optical lens assembly comprising in order from an object side to an image side:
a first lens element having an image-side surface being concave in a paraxial region thereof;
a second lens element;
a third lens element having an object-side surface being convex in a paraxial region thereof;
a fourth lens element with negative refractive power having an image-side surface being concave in a paraxial region thereof;
a fifth lens element; and
a sixth lens element with negative refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, the image-side surface having at least one convex shape in an off-axis region thereof, both of the object-side surface and the image-side surface of the sixth lens element being aspheric;
wherein an Abbe number of the fifth lens element is V5, an Abbe number of the third lens element is V3, an Abbe number of the fourth lens element is V4, and the following condition is satisfied:

1.0<V5/(V3+V4)<1.5.
