Abstract
The application discloses a camera lens assembly, and the lens assembly includes, sequentially from an object side to an image side along an optical axis: a first lens having a positive refractive power, an image side surface of which is a concave surface; a second lens having a refractive power; a third lens having a refractive power; a fourth lens having a refractive power; a fifth lens having a refractive power; a sixth lens having a positive refractive power, an object side surface of which is a concave surface; a seventh lens having a refractive power; and an eighth lens having a negative refractive power, an object side surface of which is a concave surface. 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≤2.0.
