Optical imaging lens assembly, image capturing unit and electronic device

Abstract

An optical imaging lens assembly includes four 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 and a fourth lens element. The first lens element has positive refractive power. The second lens element 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 third lens element has positive refractive power. The fourth lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof. At least one of the object-side surface and the image-side surface of at least one lens element of the optical imaging lens assembly has at least one infleciton point. When specific conditions are satisfied, the requirements of movable focus feature, telephoto feature, compactness and high image quality can be met by the optical imaging lens assembly, simultaneously.
