Provided are an optical lens assembly and an electronic apparatus including the same. The optical lens assembly implements a wide-angle lens system by including a first lens group having positive refractive power, an iris diaphragm, and a second lens group having positive refractive power, where the first lens group, the iris diaphragm, and the second lens group are arranged from an object side to an image side, and the first lens group includes at least one negative lens and two positive lenses.

Optical lens assembly and electronic apparatus including the same

An optical system may include: a first lens having positive refractive power facing an object, the first lens having a first convex face facing the object; a second lens having positive refractive power, the second lens having a second convex face facing the object; a third lens having negative refractive power, the third lens having a third concave face facing an image sensor; a fourth lens adjacent to the third lens; a fifth lens adjacent to the fourth lens, the fifth lens having a fourth face facing the object, the fourth face being convex where the fifth lens intersects the optical axis; and a sixth lens adjacent to the fifth lens. The characteristics of the optical system satisfy equation, 0.4&#x3c;f/f&#x3c;1/6 (Here, 'f' represents a focal distance of the optical system, and 'f' represents the focal distance of the second lens).

Short focus lens optical system and imaging device including the same

An imaging lens is provided. The imaging lens includes, in an order from an object side to an image plane side, a first lens having an object side surface that is convex and having a positive refractive power, a second lens having a positive or negative refractive power, a third lens having a positive or negative refractive power, a fourth lens having a negative refractive power, and a fifth lens having a positive or negative refractive power, wherein an image side surface of the fifth lens has a concave center portion and has at least one inflection point, and the imaging lens satisfies a condition that &#x2212;0.25&#x2266;(Y&#x2212;y)/y&#x2266;&#x2212;0.05, where Y denotes an image height of a real chief ray, and ydenotes an image height of a paraxial chief ray.

Imaging lens and imaging apparatus including the same

A zoom lens and a photographing apparatus including the zoom lens are provided. The zoom lens includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, and a fourth lens group having a positive refractive power, all of which are arranged sequentially from an object side to an image side. The second lens group may include a first negative lens, a second negative lens, and a first positive lens. The second lens group may also satisfy 5.6&#x2266;|fG2/fw|&#x2266;10.0, where fG2is a focal length of the second negative lens therein and fw is an overall focal length of the zoom lens at a wide-angle position.

Zoom lens and photographing apparatus having the same

An optical system of a zoom lens is provided. The optical system of the zoom lens includes thirteen lenses which are divided into four lens groups, wherein: the zoom lens comprises in a following order from a subject: a first lens group which has a positive refractive index; a second lens group which has a negative refractive index, and moves along an optical axis; a third lens group which has a positive refractive index; and a fourth lens group which has a positive refractive index, wherein the first lens group comprises four lenses, and an external surface of a first lens is concave in a direction of a plane of an image; the third lens group comprises two meniscus lenses which are concave toward an image plane, and is made with capability of cross-section displacement relative to an optical axis; and the fourth lens group is convex-concave glued lens.
