[0002] A lens is a core component of video equipment, combining optical elements with image processing capabilities. In the film and television industry, a lens refers to two things: firstly, the optical imaging component composed of lens groups used by cameras and other devices to capture images; secondly, a lens refers to a unit of continuous recording in a film or television production. Lenses can be categorized by their purpose into optical lenses and lens frames. The lens element is the core component of a lens. Traditional camera lenses are prone to chromatic aberration, affecting image quality.

An annular positioning groove 102 is provided on the inner wall of the fixing frame 100. A soft buffer ring 110 is provided on the inner wall of the annular positioning groove 102 of the fixing frame 100. In this embodiment, the soft buffer ring 110 is a soft rubber ring. In another embodiment, the soft buffer ring 110 is a soft silicone ring. In yet another embodiment, the soft buffer ring 110 is a soft plastic ring. A sliding groove 103 is provided on one side of the fixing frame 100, a sliding cavity 104 is provided inside the fixing frame 100, and a sliding through hole 105 is provided on the inner side wall of the annular positioning groove 102. The central axes of the sliding groove 103, the sliding cavity 104, and the sliding through hole 105 are located on the same straight line. The sliding groove 103 communicates with the sliding through hole 105 through the sliding cavity 104. A wire hole 106 is provided on the outer wall of the fixed frame 100, and the wire hole 106 is connected to the sliding cavity 104.

[0024] The lens body 200 is adapted to the annular positioning groove 102, and the lens body 200 is housed in the annular positioning groove 102 and abuts against the soft buffer ring 110. Both sides of the lens body 200 are provided with abrasion-resistant coating 210.

[0025] The static eliminator mechanism 300 includes a pressing plate 310, a sliding post 320, a tension spring 330, a sliding plate 340, a conductive post 350, and a conductive wire 360. In this embodiment, the pressing plate 310 is a circular plate structure. In another embodiment, the pressing plate 310 is provided with anti-slip texture. In this embodiment, the sliding post 320 is a cylindrical structure. In another embodiment, the sliding post 320 is a quadrangular prism structure. One end of the sliding post 320 is connected to the middle area of ​​the pressing plate 310, and the end of the sliding post 320 away from the pressing plate 310 is connected to the middle area of ​​the sliding plate 340. The side of the sliding plate 340 facing away from the sliding post 320 is connected to the conductive post 350. The conductive wire 360 ​​is connected to the conductive post 350 and passes through the wire hole 106 to be electrically connected to an external static eliminator. The sliding post 320 is adapted to the sliding groove 103, and is inserted into the sliding groove 103 and slidably connected to the fixed frame 100. The tension spring 330 is adapted to the sliding post 320, and is sleeved on the sliding post 320.
