Claim:
1. A camera lens comprising, in an order from an object side to an 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 negative refractive power; wherein the camera lens satisfies the following conditions (1)˜(6): where, f: overall focal distance of the camera lens; f1: focal distance of the first lens; f2: focal distance of the second lens; f4: focal distance of the fourth lens; R1: curvature radius of the first lens' object side surface; R2: curvature radius of the first lens' image side surface; R3: curvature radius of the second lens' object side surface R4: curvature radius of the second lens' image side surface d7: center thickness of the fourth lens.
