Abstract
A camera lens group, along an optical axis from an object side to an image side, sequentially includes a first lens to a seventh lens. The first lens has positive refractive power; the second lens has refractive power; the third lens has refractive power; the fourth lens has refractive power, a convex object-side surface, and a convex image-side surface; the fifth lens has refractive power, a convex object-side surface, and a concave image-side surface; the sixth lens has refractive power, and a concave image-side surface; and the seventh lens has refractive power. A total effective focal length f of the camera lens group and an entrance pupil diameter EPD of the camera lens group satisfy: f/EPD<1.45.
