Abstract

A camera lens group including, sequentially from an object side to an image side along an optical axis, a first lens having negative refractive power, a concave object-side surface and a concave image-side surface; a second lens having refractive power, a convex object-side surface and a concave image-side surface; a third lens having positive refractive power, a convex object-side surface and a convex image-side surface; a fourth lens having refractive power; a fifth lens having positive refractive power and a convex image-side surface; and a sixth lens having negative refractive power, a convex object-side surface and a concave image-side surface. Half of a field-of-view Semi-FOV of the camera lens group and half of a diagonal length ImgH of an effective pixel area on an imaging plane satisfy: 10.00 mm<tan2(Semi-FOV)*ImgH<23.50 mm. A maximum distortion of the camera lens group is less than 3.50%.
