Abstract
The present disclosure relates to optical lens, and provides a camera optical lens including eight lenses, 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 negative refractive power, a fifth lens having a negative refractive power, a sixth lens having a positive refractive power, a seventh lens, and an eighth lens having a negative refractive power; wherein the camera optical lens satisfies the following conditions: 0.95≤f/TTL; −4.00≤f2/f≤−1.80; and −20.00≤(R15+R16)/(R15−R16)≤−3.00. The camera optical lens can achieve good optical performance while meeting design requirements for a long focal length and ultra-thinness.
