Abstract
This application discloses a long-focus lens, a camera module, and an electronic device. The long-focus lens includes a first lens assembly, a second lens assembly, and a third lens assembly that are arranged from an object side to an image side. The first lens assembly and the third lens assembly are fixed lens assemblies, and the second lens assembly is a focusing lens assembly. In a focusing process in which the long-focus lens is switched from a long shot to a close-up, the second lens assembly moves toward the object side along an optical axis, a combined focal length of the first lens assembly and the second lens assembly decreases, and a combined focal length of the second lens assembly and the third lens assembly decreases. The foregoing long-focus lens has a strong focusing capability and high imaging quality.
