Camera lens
A camera lens is disclosed. The camera lens includes: 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 positive or negative refractive power, and a seventh lens with negative refractive power which are arranged sequentially from an object side to an image side. The camera lens satisfies specified conditions.
1. A camera lens, comprising in 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 positive refractive power;
a sixth lens with positive or negative refractive power;
a seventh lens with negative refractive power; wherein
the camera lens satisfies the following conditions (1)˜(2):
0.30 f 5/ f 1.00 (1);
3.00≦ R 9/ R 10≦15.00 (2); where
f: overall focal distance of the camera lens;
f5: focal distance of the fifth lens;
R9: curvature radius of the fifth lens' object side surface;
R10: curvature radius of the fifth lens' image side surface.
2. The camera lens as described in claim 1 further satisfying the following condition (3):
0.65≦ f 1/ f≦ 0.90 (3); where
f: overall focal distance of the camera lens
f3: focal distance of the first lens.
3. The camera lens as described in claim 1 further satisfying the following conditions (4)˜(6):
