Claim:
1. A camera lens, comprising, from the object side to the image side: a first lens with positive refractive power; a second lens with negative refractive power; a third lens with negative refractive power; a fourth lens with positive refractive power; a fifth lens with positive refractive power; a sixth lens with negative refractive power, wherein the camera lens satisfies the following specific conditions: where, f is the overall focal distance of the camera lens; f 1 is the focal distance of the first lens; f 3 is the focal distance of the third lens; R 3 is the object side curvature radius of the second lens; R 4 is the image side curvature radius of the second lens; d 11 is the axial distance between the image side of the fifth lens and the object side of the sixth lens.
