Abstract
The present disclosure provides a camera optical lens including, from an object side to an image side in sequence: eight lenses which are, from an object side to an image side in sequence: a first lens having a positive refractive power, a second having a positive refractive power, a third lens having a negative refractive power, a fourth lens having a refractive power, a fifth lens having a positive refractive power, a sixth lens having a positive refractive power, a seventh lens having a negative refractive power, and an eighth lens having a negative refractive power; and the camera optical lens satisfies conditions of: 0.95≤f/TTL; 2.50≤f2/f≤5.00; and −20.00≤(R15+R16)/(R15−R16)≤−3.50. The camera optical lens can achieve good optical performance while meeting the design requirements for long focal length and ultra-thinness.
