Abstract
The present disclosure discloses a camera lens group including, sequentially from an object side to an image side along an optical axis, a first lens having refractive power with a concave image-side surface; a stop; a second lens having positive refractive power with a convex image-side surface; a third lens having refractive power with a concave image-side surface; a fourth lens having positive refractive power with a convex image-side surface; and a fifth lens having negative refractive power with a convex object-side surface and a concave image-side surface. A maximum effective radius DT11 of an object-side surface of the first lens and half of a maximal field-of-view Semi-FOV of the camera lens group satisfy: 2.50 mm<tan(Semi-FOV)/DT11<5.00 mm.
