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 refractive power; a third lens element having negative refractive power; a fourth lens element having negative refractive power; a fifth lens element having refractive power; 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 image-side surface of the sixth lens element has at least one convex shape in an off-axis region thereof, and both of the object-side surface and the image-side surface of the sixth lens element are aspheric; wherein the photographing optical lens assembly has a total of six lens elements with refractive power, a focal length of the photographing optical lens assembly is f, a focal length of the third lens element is f3, a focal length of the fourth lens element is f4, a focal length of the sixth lens element is f6, a curvature radius of an image-side surface of the fifth lens element is R10, and the following conditions are satisfied:
