An optical image capturing system includes, 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. The first lens element with positive refractive power has a convex object-side surface. The second through fifth lens elements all have refractive power. The fifth lens element has a convex image-side surface. The sixth lens element with positive refractive power has both of the object-side and image-side surfaces thereof being aspheric. The seventh lens element with negative refractive power has a concave image-side surface and both of the object-side and image-side surfaces thereof being aspheric. The image-side surface of the seventh lens element changes from concave at a paraxial region to convex at a peripheral region. |
