Abstract: This application provides an optical lens, a camera module, and a terminal. The optical lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element in sequence from an object side to an image side; and each lens element of the optical lens satisfies the following relations: 0.2?BFL/TTL?0.6, and 0.2?TTL1/MIC?0.5. Therefore, the optical lens has an improved back focal length BFL and a small total on-axis thickness TTL1 of the plurality of lens elements while achieving high imaging performance. Further, a thickness of the terminal can also be reduced.

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.
