Abstract
The present disclosure discloses a camera lens assembly. The camera lens assembly includes, sequentially along an optical axis from an object side to an image side, a first lens, a second lens, a third lens, and a fourth lens. An object-side surface of the first lens and an object-side surface of the second lens are convex surfaces. An image-side surface of the third lens is a convex surface. An image-side surface of the fourth lens is a concave surface. Each of the first lens and the third lens has a positive refractive power. Each of the second lens and the fourth lens has a positive refractive power or a negative refractive power. A total effective focal length f of the camera lens assembly and an entrance pupil diameter EPD of the camera lens assembly satisfy: f/EPD<1.5.
