Abstract
The present invention provides a camera lens consisting of six lenses and having a small height, a wide angle, and good optical properties. The camera lens includes, from an object side, 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. The camera lens satisfies specific conditions.
Claims3
A camera lens, comprising, from an object side:
- 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 satisfies following conditions:
- 5.00≤DMI≤15.00;
- −5.50≤f2/f≤−3.50;
- 0.18≤d10/f≤0.30;
- and
- 0.09≤d11/f≤0.15,
- where
- DMI denotes a distortion of a maximum image height;
- f denotes a focal length of the camera lens;
- f2 denotes a focal length of the second lens;
- d10 denotes an on-axis distance from an image side surface of the fifth lens to an object side surface of the sixth lens;
- and
- d11 denotes a center thickness of the sixth lens.
