Abstract

Disclosed is a camera optical lens, comprising, from an object side to an image side in sequence: a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power; wherein, the camera optical lens satisfies: 1.40≤(R3+R4)/(R3−R4)≤5.00; −12.00≤f3/f≤−6.80; 1.30≤(R7+R8)/(R7−R8)≤4.00; 2.10≤d7/d9≤3.50; and 0.80≤d4/d6≤1.60. The camera optical lens provided by the present disclosure has a large aperture, a wide angle and ultra-thinness while having good optical performance.
