Aspects of the invention disclose an external and an add-on anamorphic lens, which comprises a focus group and an anamorphic group disposed in sequence from an object side to an image side along the optical axis. The focus group comprises a first lens and a second lens. The first lens and the second lens are spherical lenses. The anamorphic group includes a third lens, a fourth lens, and a fifth lens. These lenses are cylindrical lenses. The position of the first lens is adjustable and therefore solve the problem of requiring secondary focusing of the prior art.

Add-on anamorphic lens

The present application discloses a mobile terminal with a built-in anamorphic lens, the mobile terminal is provided with a widescreen anamorphic lens which comprises a cylindrical lens group and a spherical lens group, the cylindrical lens group at least comprises a group of cylindrical negative optical power lenses and a group of cylindrical positive optical power lenses. A widescreen anamorphic lens is arranged in the mobile terminal. The optical characteristics of the cylindrical lens in the widescreen anamorphic lens are utilized to 'compress' the incident light entering horizontally while keeping the incident light entering vertically unchanged, so the widescreen anamorphic lens may compress a widescreen image into a standard image area. After the compressed picture taken by the widescreen anamorphic lens is deformed and corrected by the image correction module, widescreen images and videos may be obtained, meeting the needs of users for widescreen shooting by the mobile terminal.

Mobile terminal with a built-in anamorphic lens

An anamorphic lens, which includes a cylindrical lens and a spherical lens arranged in sequence from the object side to the image side. The first lens, the second lens, and the third lens are arranged in sequence from the object side to the image side, the first lens and the second lens are cylindrical lenses with negative refractive power, and the third lens has positive refractive power Cylindrical lens. Using the optical characteristics of the cylindrical lens, the incoming horizontal light is 'compressed', while the light entering the vertical field of view remains unchanged. After the comprehensive aberration correction of the light, the horizontal field of view angle is increased by 33%. Achieve 1.33&#xd7; anamorphic shooting. At the same time, because the lens of this solution is smaller in size, lighter in weight, and relatively low in cost, it can better meet the needs of most ordinary users.

Anamorphic lens

An ultra-wide-angle large-aperture anamorphic lens includes a cylindrical lens group and a spherical lens group arranged in sequence from the object side to the image side. The cylindrical lens group includes a first lens, a second lens, the third lens and the fourth lens. The first lens and the second lens are negative refractive power cylindrical lenses, and the third lens and the fourth lens are positive refractive power cylindrical lenses. The spherical lens group includes a fifth lens, a sixth lens, . . . , a thirteenth lens that are sequentially arranged along the direction that the optical path points to the image side. A 2.4:1 widescreen video or photo may be obtained; at the same time, because the anamorphic lens is a front anamorphic design, in addition to the anamorphic function, it will also have optical characteristics such as elliptical out-of-focus flare and sci-fi line flare.

An anamorphic lens includes a cylindrical lens group arranged in a direction from an object side to an image side. The cylindrical lens group includes an anamorphic group and together form an imaging group. The anamorphic group includes a first lens, a second lens, and a third lens arranged in a direction of an object side to an image side. The second lens and the third lens may be joined together and the first lens may be a negative optical power biconcave cylindrical lens. Through the optical characteristics of the cylindrical lens in the anamorphic group, the entering horizontal light is compressed while the vertical light path maintains unchanged. The imaging group comprehensively corrects the light so that the horizontal field of view angle is increased by about 33% to achieve a magnification by 1.33 times for an anamorphic shooting.
