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 negative refractive power and a concave image-side surface; a stop; a second lens having positive refractive power and a convex image-side surface; a third lens having refractive power and a concave image-side surface; a fourth lens having positive refractive power and a convex image-side surface; and a fifth lens having negative refractive power, a convex object-side surface and a concave image-side surface. A maximum field-of-view FOV of the camera lens group satisfies: FOV>114°. A maximum distortion of the camera lens group is within 8%.
