Abstract
The disclosure provides a camera lens group, sequentially including, from an object side to an image side along an optical axis: a first lens with a refractive power, a second lens with a negative refractive power and an image-side surface thereof being concave, a third lens with a positive refractive power, a fourth lens with a positive refractive power and an image-side surface thereof being convex, and a fifth lens with a negative refractive power, wherein an air space is provided between any two adjacent lenses from the first lens to the fifth lens, and at least one lens from the first lens to the fifth lens is provided with an aspheric surface which is in non-rotational symmetry. An effective focal length fx, in an X-axis direction and an effective focal length fy, in a Y-axis direction, of the camera lens group satisfy 0.90<fx/fy<1.25.
