Classification: CPC G | IPC G

Claim 1:
2. The camera optical lens as described in claim 1, wherein the camera optical lens satisfies:

−4.49≤f1/f≤−1.40;

−2.30(R1+R2)/(R1−R2)≤−0.53; and

0.05≤d1/TTL≤0.14;

where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, R1 denotes a central curvature radius of an object-side surface of the first lens, R2 denotes a central curvature radius of an image-side surface of the first lens, d1 denotes an on-axis thickness of the first lens, and TTL denotes a total optical length from the object-side surface of the first lens to an image plane of the camera optical lens along an optic axis.
