В кроличью нору

This very rare lens had massive fungus and this is what happened when I tried to clean it. I've done it before loads of times and it's usually pretty simple to do. This one, however, put up more of a fight. The rear of the front element was covered in fungus, and it was so bad that even the front of the front element was covered in fungus. It was far, far worse than I thought - but I wasn't in the mood to be defeated. Elbow grease, metal polish, glass polish - something would be sure to shift it. But was I successful in cleaning the most fungus-filled lens in the world? Check out the episode, to find out! Thanks for watching!
