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.
