Abstract: A zoom lens, a camera module, and a mobile terminal. The zoom lens includes a first lens group with negative focal power, a second lens group with positive focal power, and a third lens group with negative focal power that are sequentially arranged from an object side to an image side. The first lens group is a fixed lens group. The second lens group is a zoom lens group and slides along an optical axis on an image side of the first lens group. The third lens group is a compensation lens group and slides along the optical axis on an image side of the second lens group. In addition, the zoom lens may further include a fixed fourth lens group located on an image side of the third lens group.

Abstract: This application provides a camera lens, a camera apparatus, and an electronic device. Lenses of an optical system of the camera lens are divided into two groups, and focusing of the optical system is implemented by moving one group of lenses. In this way, high imaging quality of a primary camera lens in a case in which a focus distance is infinity can be ensured and imaging quality in a case in which the focus distance is a macro distance can be improved without adding an additional wide-angle lens or a dedicated macro lens and without increasing surface process complexity and manufacturing difficulty of the primary camera lens.

Abstract: An optical lens (10), a camera module (100), and an electronic device (1000), where light that enters the optical lens (10) is axially folded by using a reflex optical element in the optical lens (10), so that the optical lens (10) can have a relatively long focal length to achieve a long-range photographing effect, and the optical lens (10) has a relatively short total track length. Therefore, when the optical lens (10) is used in the electronic device (1000), thinning of the electronic device (1000) is not affected. In addition, no prism is required to implement optical path folding in the optical lens (10).

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: 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.
