Abstract
The present invention provides a camera optical lens, including, from an object side to an image side, a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power. The camera optical lens satisfies: −2.00≤f2/f≤−1.25; —1.50≤f4/f5≤−0.80; 1.50≤d6/d8≤3.00; −1.50≤(R1+R2)/(R1−R2)≤−1.00; and 6.00≤R9/R10≤15.00. The camera optical lens has excellent optical performance while meeting the design requirements of a large aperture, a wide angle, and ultra-thinness.
