Camera lens
A camera lens is disclosed. The camera lens includes seven piece ultra-thin and high-luminous flux wide angle lenses with excellent optical properties as follows: 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 in an order 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 satisfying the following condition formulas (1)˜(2) and (4)˜(6):
0.10≦ f 2/ f 3≦0.50 (1);
0.30≦ f 5/ f≦ 1.00 (2);
18.00≦ν2=32.00 (4);
18.00≦ν3≦32.00 (5);
18.00≦ν6≦32.00 (6);
where,
f: overall focal distance of the camera lens;
f2: focal distance of the second lens;
f3: focal distance of the third lens;
f5: focal distance of the fifth lens;
ν2: abbe number of the second lens;
ν3: abbe number of the third lens;
ν6: abbe number of the sixth lens.
2. The camera lens as described in claim 1 further satisfying the following condition (3):
10.00≦| f 6|/ f≦ 100.00 (3);
where,
f: overall focal distance of the camera lens;
f6: focal distance of the sixth lens.
