Abstract
A camera optical lens includes, from an object side to an image side, a first lens having a positive refractive power; a second lens having a positive refractive power; a third lens; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power, and satisfies: 2.10≤f1/f≤4.00; 1.00≤d4/d6≤3.00; 0.20≤d8/d9≤0.90, and where f and f1 respectively denote focal lengths of the camera optical lens and the first lens; d4 denotes an on-axis distance between the second lens and the third lens; d6 denotes an on-axis distance between the third lens and the fourth lens; d8 denotes an on-axis distance between the fourth lens and the fifth lens; and d9 denotes an on-axis thickness of the fifth lens, thereby achieving good optical performance while satisfying design requirements for ultra-thinness, a wide angle and a large aperture.
