Remove old fungus with Hydrogenperoxide in Pre-Ai Nikkor 50mm 1:1.4

Who else was holding their breathe when he was taking the compass to the retaining ring? My god the suspense. This is great content!

This guy knows his stuff. Applying that much pressure without the tool slipping is not something you want to try without a lot of experience. Thumbs Up

I've always believed that you should know how to work on the equipment you own.your video not only taught me how to clean these lenses, but it also taught me how to get them apart to work on them a lot better than a lot of other videos I've seen. And with basic tools that anybody can get their hands on. Thank you for such an informative piece of content.

Well done Kenneth, as we say in English - "nothing ventured, nothing gained". Your videos are a great guide, cheers!

Love watching your attention to detail as you do these.

Thank you for adding the English commentary, I really appreciate it. I find your videos to be very informative and well done.

The “hehehe”after the successful cleaning made me happy too 😊

Weirdly relaxing, I don't even own a lens to clean, but your voice and watching the process was sort of addictive ! : )

I enjoy watching these videos and it is much better to hear you voice, watching your videos has led to my wife and I removing the front element of a Leitz Elmar F2.8 for cleaning purposes. Thanks for your inspiration.

Well done! I have the same lens and I am happy that there is no fungus among us in there. I hope I never have to perform this process, but if I do, you have helped me. Thank you.

Great video I wish i had your confidence and skills What a menace fungus is

wonderful step step by step tutorial, i was looking for ways to clean few of my old nikon and PK mount analogue lenses. Thank you again.

Superb video! I really like your English commentary - it adds so much.

I love how simple these old nikkors are built. They are very easy to dismantle, after you take each part out it looks like you are doing it on your own without much thinking. After I cleaned my 55mm 1,2f Pre AI it felt like I knew exactly how to dismantle it while I was doing it for the first time. Cant say the same thing about Russian Helios 44-6 for example... Quite tricky focusing helicoid, easy to take out hard to set it back correctly.

This is great. My repair guy fixed a nikkor 50mm 1.2 for me. He used to work for Nikon so worth the money for me for the peace of mind.

Just found this. Very nicely done. Thanks.

Very nice, thank you. As others commented, the narration adds greatly to the video.

When re-inserting a lens into its retaining ring you should always place it on a soft pillar and then lift its ring up around it until the lens lifts off the pillar. The retaining ring must first be placed the correct way up on the table and surrounding the pillar. The pillar can be anything smaller than the lens but soft enough not to damage the glass lens. Tissue will easily protect the lens from the pillar. A shot glass or a small plastic container will do for a pillar. Dropping a lens into its retaining ring is very likely to make it twist and it may lock solid and even chip the edge! Edge chips are very common on old telescopes.

I loved watching this man, do more please!

Fantastic! Thank you for the commentary as well. This was a very informative demonstration.
