摘要： The present disclosure discloses a camera lens group including, sequentially from an object side to an image side along an optical axis, a stop; a first lens having positive refractive power; a second lens having negative refractive power; a third lens having positive refractive power; a fourth lens having refractive power; a fifth lens having refractive power; a sixth lens having positive refractive power; and a seventh lens having negative refractive power. An aperture number Fno of the camera lens group satisfies: Fno≤1.53. A distance TTL along the optical axis from an object-side surface of the first lens to an imaging plane of the camera lens group and half of a diagonal length ImgH of an effective pixel area on the imaging plane of the camera lens group satisfy: TTL/ImgH≤1.31.
