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; each of the seven lens elements having 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 negative refractive power;
the fifth lens element has positive refractive power;
the sixth lens element has negative refractive power;
the image-side surface of the seventh lens element is concave in a paraxial region thereof, the image-side surface of the seventh lens element comprises at least one convex shape in an off-axis region thereof;
wherein a total number of lens elements in the optical image capturing system is seven; a central thickness of the fifth lens element is a maximum among central thicknesses 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.
