Claim 3:
4. The camera optical lens as described in claim 1, further satisfying following conditions:

−3.11≤f2/f≤−0.96;

1.25≤(R3+R4)/(R3−R4)≤5.31; and

0.01≤d3/TTL≤0.08,

where
f2 denotes a focal length of the second lens,
R3 denotes a central curvature radius of an object side surface of the second lens,
R4 denotes a central curvature radius of an image side surface of the second lens,
d3 denotes an on-axis thickness of the second lens, and
TTL denotes a total optical length from an object side surface of the first lens to an image plane of the camera optical lens along an optic axis.
