Abstract: This application discloses an optical lens, a camera module, and an electronic device. The optical lens includes a first lens group and a second lens group that are arranged from an object side to an image side, where the first lens group has positive focal power, the second lens group has negative focal power, and the first lens group and/or the second lens group are/is focusing lens groups/a focusing lens group. In a focusing process in which the optical lens switches from a long shot to a close-up shot, a spacing between the first lens group and the second lens group increases, and an effective focal length of the optical lens decreases. The optical lens satisfies a relational expression: F2/EFL>−5, where F2 is a focal length of the second lens group, and EFL is the effective focal length of the optical lens.

Abstract: A long-focus lens, a camera assembly, and an electronic device are provided. When the long-focus lens focuses on a distant view, a field of view (FOV) of the long-focus lens is less than 60°. The long-focus lens includes a first lens group and a second lens group that are arranged from an object side to an image side. The first lens group has a positive focal power, and the second lens group has a negative focal power. In a focusing process in which the long-focus lens switches focus between the distant view and a close-up view, a distance between the first lens group and the second lens group changes. The long-focus lens not only can implement telephoto shooting with high imaging quality, but also can have a strong close-up shooting capability, to implement wide-object-distance imaging from a distant view to a close-up view.

Abstract: A camera module includes a planoconvex lens, a first reflector, a focusing lens, a prime lens, a second reflector, a chip module, and a stabilization motor that are sequentially arranged from an object side to an image side. The first reflector is configured to direct an optical axis from a first direction to a second direction. The second reflector is configured to direct the optical axis from the second direction to a third direction. In this way, the photosensitive surface of the chip module may not be limited by a size of the camera module in a direction that is perpendicular to the second direction, and a large photosensitive surface design of the photosensitive surface of the chip module can be implemented.
