【オールドレンズのカビ除去】カビたシグマUCズームを使えるようにする方法！ピントリングのゴムも3dプリンターで再生します！

Lens repair. How to remove stubborn mold. I removed the mold from a junky Sigma AF telephoto zoom lens that came as a bonus with a junk camera, restoring clear images. I also used a 3D printer to regenerate the focus ring rubber. It's an eco-friendly initiative: restoring and using lenses that no one else cares about. lol This lens is very easy to maintain, and I was able to remove the lens elements relatively easily, but please be aware that it may not be as easy with other zoom lenses. 🛠️Tools are introduced on my blog. →https://paraiso.mundanoz.com/tools-an... ✨Please subscribe and like! ✨ If you enjoyed this video, please "like" and "subscribe"!
