US Patent 11782247 Camera optical lens

A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power. The camera optical lens satisfies following conditions: −3.50≤f2/f1≤−2.00; 1.00≤(R7+R8)/(R7−R8)≤5.00; f3/f≤−12.00; −2.50≤R10/R9≤−0.80; 2.00≤d7/d8≤3.20; and 0.70≤d4/d6≤1.15. The above camera optical lens may meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining a high imaging quality.
