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

*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.

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.

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

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.

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.

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

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

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.

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

Excellent démonstration. Complete with problems and how to overcome them. Easy to follow. Lots of sticky steps but done with such patience. Will tackle my Nikon fungus infected lens with confidence!

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.

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.

You give me great self-confidence? Those rubber tools are amazing! 👍👍👍👍👍

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

Many thank's, and I just now upload a new video about, Remove old fungus with Hydrogenperoxid 3% in Nikon Nikkor Pre-Ai 200mm 1:4, it is also a very intersting video on trying to clean a lens from old fungus on the lens element's. Cheers Kenneth

Hello Milenko, I just want to thank your remarkable intelligence, having no appropriate tools and sometimes guessing the result you come out with success, never has been easy to remove fungus from a lens indeed is sometimes very difficult myself couldn't clean my Nikon binoculars from fungus traces, all good optics are made in a milimetrical way disassembling could be sometimes easy, putting all together again is not. Forget about the I-Know-All guys, they maybe professionals on it, you are the genious here, THANKS for demonstrating that the Okhams razor works here as in all big cientific deals+++

Wow! I just wrote a comment on another video saying that I had a fungus spot on a Zuiko 50mm f/1.4 and your video appears on my recommended list. I need to get the courage to dismantle it. This is a really useful video!!

I've watched this one several times in the last 2 years. There's nothing like restoring one of these old pieces to shiny optical loveliness, especially when they looked a bit forgone.

On Ebay this lens is now worth at least 2x this. Cleaning the glasses took just a few minutes. I like this channel.

I love the high tech lens disassembly tool, with flowers yet ! You could spend $500.00 and not get a better tool, and it can’t damage the device, amazing

Thanks for this video. I was listening to it while taking an old Practiker lens apart and it gave me a few ideas for how to go about it. I wouldn't have known about the hydrogen peroxide too.

Good to see someone carrying out professional work without all the professional tools, which are sometimes very expensive and little used. A Job well done, without someone saying how you have all these crazy expensive specialist tools, just straightforward equipment anyone may have or could buy cheaply, plus a steady hand and a little bit of know how;)

Thank you kind sir a lot of good information and no music ..wonderful.

An excellent and informative video, good to see the tools you are using, many thanks.

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

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

Thank you very, very, very, very much; I wish I knew this ten years ago because of the several quality used lenses I turned down from buying secondhand.

Very very interesting and educational. Hydrogen Peroxide is interesting stuff - I use it (at the same percentages as you use) to clean my orchid roots when repotting. I love those old lenses, I use old Canon's and Pentax cameras - the glass is fabulous.

Just completed the oxidation and removal of fungus on my Nikkor 50mm f1.8 lens at back of the front element with 6% hydrogen peroxide, and it worked! Thanks Kenneth!

Cracking video so well explained. Going to find some old secondhand lens to practice on first! Cheers!

Fascinating. Thank you for putting this video out. The prospect of dismantling a lens, and hopefully putting it all back together, seemed rather daunting before watching this. Although I wouldn't necessarily try it myself, it's good to see it's not 'brain surgery' skill :) More modern lens with all the electronics would be undoubtedly more of a challenge I can assume though.

You're da man... Nicely explained, I have some Carl Zeiss Jena lenses with fungus (the famous 2.8 / 180 for 6x6 e.g.) which I have new hope for now. Thank you a lot dude.

For the rings I made my wrench out of a cheap pair of vernier calipers. I had to square off the inside measuring pieces but it was worth it to have a tool that doesn't flex and slip. Those calipers you used are fine because of necessity but if anyone is looking around for something to sacrifice to the job - file up the vernier calipers for 12 bucks or less.

Many thanks for your time and expertise!

Thank you for sharing this treasure!

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.

Thank you for this wonderful video! I am just starting to try my hand at making cinematic short films. The kit lens with my dslr is not the best, but I had my old camera bag from the 80’s and 90’s in a closet. $20 adapter rings would save many $1000’s in new glass. Unfortunately all have gotten fungus in them. The perils of living in Florida, I suppose. But now I’m going to try my hand at cleaning them so I can use them. Again many thanks!

That sound's great with the use of old lens to make video's and film's, some of the old lenses has a great bokhe and they can render the pictures very good and different compare to new and crystal clear (but a little boring..) lenses. It's not a hard job to fix the old manuel focus lenses, one just have the correct tool's and the correct cleaning fluid. Here is some link to some repair tools.

This is interesting! I pulled out my Tassco spotting scope last week and to my surprise the zoom eyepiece was sporting the same symptoms. Didn't know what it was other than moisture related. Cleaned affected lenses with just glass cleaner and allowed them to dry. Reassembled and no issues. Now that I know its fungus relatedI I'll bring out my UV Prom chip eraser and let it shine down the apertures from both ends for a while followed by placing it in an airtight container with silica gel kitty litter that I have dried even better, fresh out of the bag and holding in a sealed mason jar until I need to use it. Great video, one recommendation is that the retainer ring used on the last lens group appeared to have been scratched when the dividers slipped. You might want to give it a coating of lamp black or what is more commonly called soot. You can use a tall candle flame that is smokey and give it a coat to kill the shininess of the metal. This way you will not experience strange reflections within the lens.

This works, fungus webs on the rear element of a mint condition 135mm f3.5 for $20.00. Look just like this. Spanner wrench is a must to have. It worked now it's crystal clear. 9:58 the death grip, i always am waiting for it to slip and take out my glass.

Thanks for sharing. I've been looking for this kind of work process of how to work on old lenses for quite sometime now. This is very helpful for me cause I still use old lenses with my DSLR for shooting video. Please, show us more of how to do more works to save old beautiful glass and f-stop like the high speed lenses. Again, thank you very much for your informative lesson.

Thank you very much for sharing this knowledge. This was very useful to me!

Excellent work! Thank you for that very useful tip. I have a Nikkor lens (35mm - 70mm F2.8) that someone sold me a year ago and they misrepresented the extent of fungus damage. In fact, they claimed it had none and their images of the lens were taken in such a way as to not allow the bidder to see the fungus. Long story short, I should have just returned it but for some stupid reason, I just complained that it wasn't worth the price I won it for and suggested that I would keep it if he refunded $50 of the $250 I paid. I think I was tired and thought he would object and reject my counter offer. Then I figured I would send it back and be done with it. However, he accepted the counter offer and refunded me $50... I am now stuck with a lens that I couldn't sell for 1/10th of what I paid for it. I'm going to try to use that cleaning process. I have many tools and am a first class machinist (retired) by trade. However, I'm going to have to find a set of rubber cups like those that you used to unscrew the various lens sections. I need to see if you happened to list where you got those from. I should be able to find a spanner wrench somewhere but if I can't, I can always make one. The 35-70mm F2.8 lens was a good lens in its day but the fungus really made it practically useless. The camera I shoot with most of the time is heavy enough, (Nikon D4S), and this 30/70mm lens is quite heavy for such a small lens but I may keep it if I can clean it. Thanks again, Rich

Great video and very informative, even though I winced when you were using metal tools with force on a glass element! Otherwise, many thanks and I will dig out my 1960s fungus infested lenses immediately.

Very useful and thorough video with links.

the internal construction should be the same, the only external difference on an AI lens is the back of the aperture ring has notches on it to line up with the auto indexing mechanism on later Nikon bodies, where Non AI lenses the back of the aperture ring is smooth all the way around. there are a lot of tutorials on here that will explain and show it in detail so you know exactly what your'e looking at.

Nice video. Unfortunately if the fungus has been in the lens for too long, it eats into the optical coating and creates a permanent haze. I acquired a couple of lenses with that condition and beyond repair.. One lens, I was able to easily pull the front element out (200mm f/2.5) and clean the fungus off.

Hello. I worked in a camera repair store in Washington, D.C. for a year fixing cameras, from cheapo snap shot, to Leicas and Exactas. The lens technician, very nice quiet guy, showed me some of his repairs and cleaning lenses. From what I remember, he never used lighter fluid on the actual glass element, only glass cleaner. Lighter fluid is an oil, and leaves a film on the surface. So, unless you clean that off, it can change the performance of the glass, and may actually promote fungus or clouding. Otherwise, a nice tutorial, and I will have dig out some old lenses and try this. It makes so much sense to use peroxide, but I have never heard of it.

@birdtower2801

I'm sorry but you're wrong about lighter fluid. Lighter fluid, as all petroleum distillates, is not an oil. Quite the opposite actually: they are very good solvents, furthermore, they evaporate quite rapidly, so there's no need to wipe them off. That said I don't know if lighter fluid is adequate for cleaning lenses.

Great job. Thank you.

Hey I need help to open double front element lens on sony 55-210 lens, how to open that?

Nice work! Fortunately the lens coating seems intact. Was hydrogen peroxide really required? My very old large format camera lens seemed to have an organic coating. The fungus came off with ordinary lens cleaner but the coating had been eaten away in some areas. The camera produces good negatives but I didn't feel so good after so much labour. Same with my monocular scope. Thanks for the video!

Lighter fluid combined with friction of the mechanical cleaning surely can wipe away soft coatings of older lenses. Be careful!
