Lens limiting assembly, camera body, and camera

A lens limiting assembly (100) is used for limiting a lens (310) that has a retaining body (314) arranged on the outer side. The lens limiting assembly (100) comprises an elastic element (10), a lens assembly ring (20) and a locking ring (30). The lens assembly ring (20) is arranged on the elastic element (10). After the lens (310) is assembled in the lens assembly ring (20), the retaining body (314) is retained below the elastic element (10). When the locking ring (30) rotates in a direction, the locking ring (30) rests on and presses against the elastic element (10), so that the elastic element (10) presses against the retaining body (314) of the lens and therefore the lens (310) is locked.
