Abstract
A camera lens group sequentially includes, from an object side to an image side along an optical axis: a first lens (E1) with a refractive power, wherein an object-side surface (S1) thereof is a concave surface, while an image-side surface (S2) is a convex surface; a second lens (E2) with a refractive power, wherein an object-side surface (S3) is a convex surface, while an image-side surface (S4) is a concave surface; a third lens (E3) with a positive refractive power; a fourth lens (E4) with a refractive power; a fifth lens (E5) with a positive refractive power, wherein an object-side surface (S9) thereof is a concave surface, while an image-side surface (S10) is a convex surface; and a sixth lens (E6) with a negative refractive power, wherein an object-side surface (S11) thereof is a convex surface, while an image-side surface (S12) is a concave surface. A half ImgH of a diagonal length of an effective pixel region on an imaging surface (S15) of the camera lens group meets ImgH>4.60 mm.
