The present disclosure provides a camera optical lens including, from an object side to an image side in sequence: a first lens having a positive refractive power, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens; and the camera optical lens satisfies conditions of: 0.95≤f/TTL; 4.00≤f2/f≤6.00; and −15.00≤(R7+R8)/(R7−R8)≤−2.50. The camera optical lens can achieve good optical performance while meeting the design requirements for large aperture, ultra-thinness and long focal length.
