Abstract: An optical lens (10), a lens module (100), and a terminal (1000) are provided. The optical lens (10) includes a first constituent element (S1), a second constituent element (S2), a third constituent element (S3), and a fourth constituent element (S4) arranged from an object side to an image side, and each of the constituent elements includes at least one lens element. The optical lens (10) satisfies the following relations: 9.08≤BFL≤11.745; and 0.6≤BFL/TTL≤0.67. In this way, the optical lens (10) can obtain a long back focal length BFL, and long-focus photographing of the optical lens (10) is implemented. In addition, an axial thickness TTL1 of a plurality of lenses of the optical lens (10) is small, so that a thickness of the terminal (1000) including the optical lens (10) may also be small.

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.

Abstract: A zoom lens includes a first lens group, a second lens group, a third lens group, and a fourth lens group that are sequentially arranged from an object side to an image side along an optical axis. The first lens group and the third lens group are fastened, and the second lens group and the fourth lens group move along the optical axis. A first lens from the object side in the first lens group is a biconvex lens, and at least two lenses from the object side in the first lens group are glass lenses. A maximum clear aperture diameter of the zoom lens has the following relationship of 4 mm≤φ≤12 mm, where p is the maximum clear aperture diameter of the zoom lens.
