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; 3.20≤f2/f≤5.00; and 0.20≤(R11+R12)/(R11−R12)≤0.90. The camera optical lens can achieve good optical performance while meeting the design requirements for long focal length and ultra-thinness.
