The present disclosure relates to optical lenses, camera modules, and electronic devices. One example optical lens includes a front lens element group, a first reflector, and a rear lens element group that are sequentially arranged in a direction from an object side to an image side. The first reflector is configured to reflect a ray from the front lens element group to the rear lens element group. The front lens element group is a fixed lens element group, and the first reflector is rotatably disposed in the lens to implement optical image stabilization.
