The presenter lifts the camera, removes the inner plastic ring, and slides the flat‑head screwdriver around the lens until it reaches three small rivets. By gently pushing upward, each rivet pops out, freeing the front glass element. With the ring removed, three front‑element screws become visible; the demonstrator clamps the screwdriver to hold it steady and carefully tightens each screw with the Phillips driver, stopping short of stripping and testing the tightness repeatedly until the element no longer moves. After the screws are secured, the front ring is re‑installed, aligning its three holes with the rivets and gently pressed back into place. Dust that had collected under the ring is cleared with glass cleaner and the microfiber cloth. The lens is then wiped clean, a thumbs‑up is shown, and the presenter rotates the lens to inspect it before the video ends."
