视频中，一个人正在展示和操作一个相机镜头。他用右手拿着镜头，左手则拿着一台相机。镜头上标有“SONY”的标志，表明这是一个索尼品牌的镜头。这个人先是将镜头的盖子取下，然后展示了镜头的前端，可以看到镜头上的各种标识和参数。背景模糊，主要焦点集中在镜头和相机上。桌子上还放着一些工具和其他物品，但它们并不清晰可见。
The video shows a person holding a camera lens in their right hand and a camera body in their left hand. The person is unscrewing the lens cap from the lens, revealing the front element of the lens. The background is slightly blurred, indicating that the focus is on the hands and the camera equipment. The setting appears to be indoors, possibly at a desk or table with some tools visible in the background.
A person holds a camera lens in their right hand and rotates it to show different angles. The lens is initially shown with the front element facing the camera, revealing the internal components. As the person continues to rotate the lens, the brand 'Sony' becomes visible on the side. The rotation reveals the lens's outer casing and the lens mount. Further rotation shows the lens's rear element, which has the 'Zeiss' and 'Sony FE 2.8/35 ZA' markings. The background is a plain, light-colored wall, and the person is seated at a table with some tools and equipment visible in the background.
