Claim 9:
10. The optical camera lens as described in claim 1, further satisfying following conditions:

−1.46≤f9/f≤−0.47;

0.14≤(R17+R18)/(R17−R18)≤0.68; and

0.04≤d17/TTL≤0.12,

where f9 denotes a focal length of the ninth lens, R17 denotes a central curvature radius of an object side surface of the ninth lens, R18 denotes a central curvature radius of an image side surface of the ninth lens, d17 denotes an on-axis thickness of the ninth lens, and TL 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.
