Abstract
The present application discloses a camera lens assembly and a camera device equipped with the camera lens assembly. The camera lens assembly includes: a first lens adjacent to an object side and having positive focal power and multiple subsequent lenses arranged in sequence from the first lens to an image side along an optical axis, where the focal power of the first lens satisfies the following formula: 2.0<f/f1<3.0, where f is a total effective focal length jointly determined by the first lens and the multiple subsequent lenses, and f1 is an effective focal length of the first lens. The camera lens assembly has telephoto function and can meet the users' requirements for higher image quality and miniaturization.
