Claim Text:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof; a second lens element having negative refractive power; a third lens element; a fourth lens element; a fifth lens element with negative refractive power having an object-side surface being concave in a paraxial region thereof, wherein the object-side surface and an image-side surface of the fifth lens element are aspheric; and a sixth lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, wherein the object-side surface and the image-side surface of the sixth lens element are aspheric, and at least one of the object-side surface and the image-side surface of the sixth lens element has at least one inflection point; wherein the photographing optical lens assembly has a total of six lens elements, a focal length of the photographing optical lens assembly is f, a focal length of the fourth lens element is f4, a vertical distance between a non-axial critical point on the image-side surface of the sixth lens element and an optical axis is Yc62, a curvature radius of an object-side surface of the third lens element is R5, a curvature radius of an image-side surface of the third lens element is R6, a curvature radius of the object-side surface of the fifth lens element is R9, a curvature radius of the image-side surface of the fifth lens element is R10, and the following conditions are satisfied:
