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, a convex 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 refractive power and a concave object-side surface; a sixth lens having positive refractive power, a convex object-side surface and a convex image-side surface; and a seventh lens having negative refractive power. A maximum field-of-view FOV of the camera lens group satisfies: FOV>133.0°. An amount of distortion of the camera lens group is below 25.0%.
