1. An optical image capturing system comprising seven lens elements, the seven 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, a sixth lens element, and a seventh lens element;
wherein each of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element, the sixth lens element and the seventh lens element 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 second lens element has negative refractive power; the fifth lens element has negative refractive power; the object-side surface of the seventh lens element comprises at least one inflection point; a central thickness of the second lens element is smaller than a central thickness of the third lens element; an axial distance between the first lens element and the second lens element is smaller than an axial distance between the sixth lens element and the seventh lens element;
wherein a focal length of the optical image capturing system is f, a focal length of the third lens element is f3, a focal length of the fourth lens element is f4, an Abbe number of the first lens element is V1, an Abbe number of the second lens element is V2, and the following conditions are satisfied:
|f/f3|+|f/f4|<1.0; and
28<V1−V2<42.
