Abstract: This application provides an example optical lens, an example camera module, and an example terminal. One example lens includes a first lens with a negative focal power, a second lens with a positive focal power, a third lens with a negative focal power, a fourth lens with a positive focal power, a fifth lens with a positive focal power, a sixth lens with a focal power, and a seventh lens with a focal power that are sequentially arranged along an optical axis from an object side to an image side. The first lens includes an object side surface that is concave near the optical axis and an image side surface that is convex near the optical axis. The seventh lens is an M-shaped lens and includes an object side surface that is convex near the optical axis and an image side surface that is concave near the optical axis.
