Abstract: This application provides an optical lens, a camera module, and a terminal. The optical lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element in sequence from an object side to an image side; and each lens element of the optical lens satisfies the following relations: 0.2≤BFL/TTL≤0.6, and 0.2≤TTL1/MIC≤0.5. Therefore, the optical lens has an improved back focal length BFL and a small total on-axis thickness TTL1 of the plurality of lens elements while achieving high imaging performance. Further, a thickness of the terminal can also be reduced.

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: A camera module, which may be included in an electronic device includes a camera lens, a variable aperture, and a photosensitive element. A quantity of apertures of the camera lens is F1 when a clear aperture of the variable aperture is adjusted to a first clear aperture, and the photosensitive element is configured to: enable the camera lens to perform imaging in a full area of a photosensitive area, and adjust angular resolution of the full area to δ. A quantity of apertures of the camera lens is F2 when a clear aperture of the variable aperture is adjusted to a second clear aperture, where F1≥F2, and the photosensitive element is configured to: enable the camera lens to perform imaging in a partial area of the photosensitive area, and adjust angular resolution of the partial area to nδ, where 1≤n≤3.

Abstract: This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first lens element group and a second lens element group. The first lens element group and the second lens element group each include a plurality of lens elements. In different use scenarios, the second lens element group can be moved to change a distance between the first lens element group and the second lens element group, to change a focal length of the optical lens. This ensures that the optical lens in this application can achieve a good shooting effect in different use scenarios. In this application, the second lens element group is disposed within a back focal length range of the first lens element group. In this way, a total track length of the optical lens in this application can be small, so that the optical lens can be used within a thin electronic device.
