1. An optical photographing lens assembly comprising five lens elements, the five 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 and a fifth lens element;
wherein each of the five lens elements has an object-side surface towards the object side and an image-side surface towards the image side;
wherein the first lens element has negative refractive power; the third lens element has positive refractive power; the fourth lens element has the image-side surface being convex in a paraxial region thereof; at least one of the object-side surfaces and the image-side surfaces of the first lens element to the fifth lens element has at least one inflection point;
wherein a central thickness of the first lens element is greater than an axial distance between the first lens element and the second lens element; an absolute value of a curvature radius of the object-side surface of the third lens element is greater than an absolute value of a curvature radius of the object-side surface of the fourth lens element; an absolute value of a curvature radius of the object-side surface of the first lens element is greater than an absolute value of a curvature radius of the image-side surface of the fifth lens element; a curvature radius of the image-side surface of the third lens element and the curvature radius of the object-side surface of the fourth lens element have different signs; an absolute value of a focal length of the second lens element is greater than an absolute value of a focal length of the fourth lens element.
