摘要： An optical image capturing lens assembly 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 and a fifth lens element. The first lens element with refractive power has a concave object-side surface, and the object-side surface changes from concave at a paraxial region to convex at a peripheral region. The second lens element has refractive power. The third lens element has positive refractive power. The fourth lens element has negative refractive power. The fifth lens element with positive refractive power has a convex object-side surface and a concave image-side surface, wherein the image-side surface changes from concave at a paraxial region to convex at a peripheral region. The object-side surfaces and the image-side surfaces of the first and fifth lens elements are aspheric.
