Classification: CPC G | IPC G

Claim 0:
1. A camera optical lens comprising, from an object side to an image side in sequence: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens; wherein the first lens has a positive refractive power, and the camera optical lens satisfies conditions of:

0.95≤f/TTL; 

3.50≤f2/f≤5.50; and

−20.00≤(R5+R6)/(R5−R6)≤−3.00;

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;
R5 denotes a central curvature radius of an object-side surface of the third lens;
R6 denotes a central curvature radius of an image-side surface of the third lens.
