Abstract
The present disclosure discloses a camera lens group. The camera lens group sequentially includes, from an object side to an image side along an optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens has a positive refractive power and a convex object-side surface. The second lens has a positive refractive power and a convex object-side surface. The third lens has a refractive power and a concave image-side surface. The fourth lens has a refractive power. The fifth lens has a refractive power. The sixth lens has a positive refractive power and a convex image-side surface. The seventh lens has a negative refractive power, and a concave object-side surface and a concave image-side surface. A total effective focal length f and an entrance pupil diameter EPD of the camera lens group satisfy: f/EPD≤1.60.
