PHOTOGRAPHING LENS ASSEMBLY, IMAGE CAPTURING DEVICE AND MOBILE TERMINAL

摘要

A photographing lens assembly includes, 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, and a sixth lens element, which has a total of six non-cemented lens elements with refractive power. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The second lens element with refractive power has an object-side surface being concave in a paraxial region thereof. The third and the fourth lens elements have refractive power. The fifth lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The sixth lens element with refractive power has an image-side surface being concave in a paraxial region thereof.
