Abstract: A camera module comprises an image sensor having a size greater than or equal to 1/3.06 inch and less than or equal to 1/2.78 inch and a lens module comprising at least five lenses disposed in sequence between an object side and an image side of the camera module. A ratio between a half-image height of the lens module and a total track length of the camera module is greater than or equal to 0.5 and less than or equal to 0.6. A field of view of the lens module is greater than or equal to 100 degrees. An aperture of the lens module is greater than or equal to F1.8 and less than or equal to F2.4. An equivalent focal length of the lens module is greater than or equal to 10 mm and less than or equal to 20 mm.

Abstract: This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens that are sequentially arranged from an object side to an image side. The first lens, the third lens, and the fifth lens all have positive focal power, the second lens and the fourth lens both have negative focal power, and the sixth lens has positive focal power or negative focal power. Object side surfaces and image side surfaces of the first lens to the sixth lens include at least one anamorphic aspherical surface. When the optical lens is applied to the camera module and the electronic device, the camera module and the electronic device can implement ultra-wide-angle photographing, and can also resolve a distortion problem in ultra-wide-angle imaging to a large degree.
