Patent ID: 11287615

Abstract:
A camera lens group including a first to a fifth lens arranged sequentially from the object side to image side is provided. The first lens has a positive refractive power, and object-side surface thereof is a convex surface; the second lens has a negative refractive power, and image-side surface thereof is a concave surface; the third and the fourth lens each has a refractive power, and an object-side surface of the third lens is a convex surface; the fifth lens has a negative refractive power, and an image-side surface thereof is a concave surface; an effective focal length f of the camera lens group and half of a diagonal length ImgH of an effective pixel area on an image plane of the camera lens group satisfy: 3.5<f/ImgH<4.5; and an effective focal length f1 of the first lens and an entrance pupil diameter EPD of the camera lens group satisfy: 3<f1/EPD<4.5.
