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.

Abstract: An inner focusing lens unit includes at least one positive lens group and at least one negative lens group. The inner focusing lens unit is configured to be placed within a flange back between an imaging lens and an image sensor surface to provide a focusing function when the negative lens group is moved toward the imaging surface to focus at a nearer object distance when focusing from infinity to a minimum object distance (MOD).
