Abstract: A photographing lens assembly includes eight lens elements which are, 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, a fifth lens element, a sixth lens element, a seventh lens element and an eighth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The sixth lens element has an image-side surface being concave in a paraxial region thereof. The seventh lens element has an image-side surface being concave in a paraxial region thereof. The eighth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof, and the image-side surface of the eighth lens element has at least one critical point in an off-axis region thereof.
