Claim 2:
3. The optical camera lens as described in claim 1, further satisfying following conditions:

0.76≤f2/f≤3.19;

−4.09≤(R3+R4)/(R3−R4)≤−1.10; and

0.03≤d3/TTL≤0.09,

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 the image side surface 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.
