Abstract
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.

A camera optical lens comprising, 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;
- wherein 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;
- where
- TTL denotes a total optical length from an object-side surface of the first lens to an image surface of the camera optical lens along an optical axis;
- f denotes a focal length of the camera optical lens;
- f2 denotes a focal length of the second lens;
- R11 denotes a central curvature radius of an object-side surface of the sixth lens;
- and
- R12 denotes a central curvature radius of an image-side surface of the sixth lens.
