Abstract

Provided is a camera optical lens including, sequentially 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; and a fourth lens having a negative refractive power. The camera optical lens satisfies following conditions: 2.00≤(f1+f3)/f≤2.30; −8.60≤(f2+f4)/f≤−4.80; −2.10≤(R1+R2)/(R1−R2)≤−1.90; −4.00≤(R3+R4)/(R3−R4)≤−1.00; and 2.00≤(R7+R8)/(R7−R8)≤3.40. The camera optical lens can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
