Claim of US Patent No. 10,558,018

1. A camera lens comprising, from an object side to an image side in sequence: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, and a sixth lens having a negative refractive power; wherein the camera lens further satisfies the following conditions (1)˜(3):10.00?f3/f?15.00  (1)
?4.80?(R5+R6)/(R5?R6)??4.20  (2)
0.50?(R9+R10)/(R9?R10)?0.70  (3)
where
f: the focal length of the camera lens;
f3: the focal length of the third lens;
R5: the curvature radius of the object side surface of the third lens;
R6: the curvature radius of the image side surface of the third lens;
R9: the curvature radius of the object side surface of the fifth lens;
R10: the curvature radius of the image side surface of the fifth lens.
