Photographing optical lens assembly, image capturing unit and electronic device

Abstract

A photographing optical lens assembly includes eight lens elements which are, in order from an object side to an image side along an optical path: 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. Each of the eight lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The first lens element has negative refractive power. The image-side surface of the second lens element is concave in a paraxial region thereof. The image-side surface of the fourth lens element is convex in a paraxial region thereof. The fifth lens element has positive refractive power, the object-side surface of the fifth lens element is convex in a paraxial region thereof, and the image-side surface of the fifth lens element is convex in a paraxial region thereof. The sixth lens element has negative refractive power, and the image-side surface of the sixth lens element is concave in a paraxial region thereof. The seventh lens element has positive refractive power. The image-side surface of the eighth lens element is concave in a paraxial region thereof, and the image-side surface of the eighth lens element has at least one inflection point. When specific conditions are satisfied, the requirements of wide field of view, compact size and high image quality can be met by the photographing optical lens assembly, simultaneously.
