Claim 3:
4. The camera optical lens as described in claim 1, further satisfying following conditions:
0.84≤f2/f≤11.93;
0.81≤(R3+R4)/(R3−R4)≤8.48; and
0.05≤d3/TTL≤0.16,
where
f denotes a focal length of the camera optical 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.
