Claim Text:
1. A photographing 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 having positive refractive power, wherein both of an object-side surface and an image-side surface of the third lens element are aspheric; a fourth lens element having refractive power, wherein both of an object-side surface and an image-side surface of the fourth lens element are aspheric; a fifth lens element having negative refractive power, wherein both of an 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 concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof, wherein both of the object-side surface and the image-side surface of the sixth lens element are aspheric; wherein the photographing lens assembly has a total of six lens elements with refractive power; there is an air gap in a paraxial region between every two of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element that are adjacent to each other; wherein the photographing lens assembly further comprises a stop; an axial distance between the second lens element and the third lens element is T23, an axial distance between the third lens element and the fourth lens element is T34, an axial distance between the stop and the image-side surface of the sixth lens element is SD, an axial distance between the object-side surface of the first lens element and the image-side surface of the sixth lens element is TD, and the following conditions are satisfied:
