Claim 2:
3. The camera optical lens as described in claim 1, further satisfying following conditions:
−3.14≤f2/f≤−0.52;
−0.04≤(R3+R4)/(R3−R4)≤6.80; and
0.01≤d3/TTL≤0.04,
where
f2 denotes a focal length of the second lens;
R3 denotes a curvature radius of an object side surface of the second lens;
R4 denotes a curvature radius of the 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.
