Abstract
An image capturing lens system includes a first lens having negative refractive power, a second lens having positive refractive power while having a convex object-side surface, a third lens having positive refractive power, a fourth lens having positive refractive power, a fifth lens having negative refractive power with a concave object-side surface and a concave image-side surface, and a sixth lens having positive refractive power.
Claims15
An image capturing lens system comprising:
- a first lens having a negative refractive power;
- a second lens having a positive refractive power, and a convex object-side surface, and a convex image-side surface;
- a third lens having a positive refractive power and a concave object-side surface;
- a fourth lens having a positive refractive power;
- a fifth lens having a negative refractive power, a concave object-side surface, and a concave image-side surface at an optical axis of the image capturing lens system;
- and
- a sixth lens having a positive refractive power,
- wherein the first to sixth lenses are sequentially disposed in ascending numerical order from an object side of the image capturing lens system toward an imaging plane of the image capturing lens system, and
- wherein the image capturing lens system comprises no more than six lenses with refractive power.

An image capturing lens system comprising:
- a first lens having a refractive power;
- a second lens having a refractive power and a concave image-side surface;
- a third lens having a refractive power and a concave object-side surface at an optical axis of the image capturing lens system;
- a fourth lens having a refractive power;
- a fifth lens having a negative refractive power and comprising a concave image-side surface at the optical axis of the image capturing lens system;
- a sixth lens having a refractive power;
- and
- a stop disposed between the second lens and the third lens,
- wherein the first to sixth lenses are sequentially disposed in ascending numerical order from an object side of the image capturing lens system toward an imaging plane of the image capturing lens system,
- wherein the third lens or the fourth lens is made of glass,
- wherein the following conditional expression is satisfied:
- 0.7<BFL/S8S13
- where BFL is a distance from an image-side surface of the sixth lens to an imaging plane, and S8S13 is a distance from an object-side surface of the fourth lens to an image-side surface of the sixth lens, and
- wherein the first to sixth lenses are the only lenses having a refractive power in the image capturing lens system.
