Claim:
1. An optical image capturing system comprising, in order from an object side to an image side thereof, 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 toward the object side, and an image-side surface facing toward the image side, wherein: the first lens element having positive refractive power; the second lens element having negative refractive power, the fifth lens element having the object-side surface and the image-side surface being both aspheric; the sixth lens element with positive refractive power having at least one convex shape at a peripheral region of the image-side surface thereof, wherein the object-side surface and the image-side surface of the sixth lens element are both aspheric; and the seventh lens element with negative refractive power having at least one convex shape at a peripheral region of the image-side surface thereof, wherein the object-side surface and the image-side surface of the seventh lens element are both aspheric, and at least one of the object-side surface and the image-side surface of the seventh lens element has at least one inflection point thereon; wherein the optical image capturing system has a total of seven lens elements, a maximal field of view of the optical image capturing system is FOV, an Abbe number of the first lens element is V1, an Abbe number of the second lens element is V2, and the following relationships are satisfied:
