Abstract
A camera lens assembly is provided. The camera lens assembly, comprises sequentially, from an object side to an image side along an optical axis, a first lens, multiple subsequent lenses, and a photosensitive element arranged on an image plane, wherein the first lens has a negative focal power and an object side surface of the first lens is a concave surface; and an axial distance from the object side surface of the first lens to the image plane TTL and ImgH, ImgH being half a diagonal length of an effective pixel area of the photosensitive element, satisfy: 1.5<TTL/ImgH<1.7.
