A camera lens assembly providing focal length adjustment to permit mounting in a personal portable terminal. The camera lens assembly includes a lens assembly; a driving unit provided in one side of the lens assembly; and a guide section provided between the lens assembly and the driving unit, wherein the lens assembly moves forward and backward in a direction of an optical axis to the driving unit by guidance of the guide section. The guide section enhances an auto-focusing function and simplifies mounting of the camera lens assembly, rendering it possible to secure portability even when a camera is mounted to a miniaturized personal portable device such as a mobile communication terminal, a portable computer or the like.
