PHOTOGRAPHING OPTICAL LENS ASSEMBLY, IMAGE CAPTURING DEVICE AND MOBILE TERMINAL

摘要

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