1. An optical image capturing 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 image-side surface of the first lens element is concave in a paraxial region thereof; the second lens element has negative refractive power, the object-side surface of the second lens element is convex in a paraxial region thereof, and the image-side surface of the second lens element is concave in a paraxial region thereof; the object-side surface of the third lens element is convex in a paraxial region thereof; the image-side surface of the fourth lens element is convex in a paraxial region thereof; the image-side surface of the fifth lens element is concave in a paraxial region thereof; at least one of the object-side surface and the image-side surface of the sixth lens element comprises at least one inflection point;
wherein a curvature radius of the object-side surface of the sixth lens element is R11, a curvature radius of the image-side surface of the sixth lens element is R12, and the following relationship is satisfied:
−0.85≤R11/R12≤0.05.
