Not only did you clean the glasses of the lens, you also restored the entire lens and reuse this amazing piece of vintage gear. Keep these kind of content coming, Mathieu!
Did the same with my Biotar 75/1.5 last year. The fungus damaged the glass permanently leaving some marks. Still, the lenses performs great and I paid basically nothing for it. Always worth trying to save these beauties. Good job, sir!
@@nathanwatson3298 i was totally aware of it. That's why I jumped on the rusty lens I found online. Here in Germany there is a good market, but even here the prices for those old treasures are really crazy everywhere.
@@berner81 How tricky was it to clean? I've heard the old Zeiss lenses-especially one like that-are so intricate it's best to leave to a professional.
@mathieustern did you replace the balsam glue? I assume the glue was used to chemically bond two of the glass elements. Were you able to get those results without gluing them back together? If you did glue them, did you use balsam glue or UV sensitive glue? Thanks in advance.
Interesting question..
Le dot..... Just want to ask the same question...
incredible what images were produced after you cleaned the fungus off. the lens itself has so much character
We really need people like you more on such platforms. Thanks a ton for doing what you do 🌹
I love to see that someone cares for these aged items & wants to give them a 2nd chance. The images are beautiful, certainly worth the effort put in. I love knowing it’s one less item to wind up in a landfill.
Marvelous! Only thing i can say is:
Instead of sharpie to paint the lens, try to use matte black to avoid light reflections, and ensure your body is still fully black in the inside to (again) avoid weird light effects.
I'm pretty sure you already know this because you are way more aknowledged than me, but still, just in case. Cheers!
Be careful with lens vise tools! I recently cleaned up a couple of Canon FD 50mm 1.4 SSC lenses and one had a warped rear element tube that needed to be stretched to get the glass out to clean and it gently cracked the last doublet element which now gives a slight rainbow flare on the side, not a bad effect as it’s otherwise fine with no light flare. However, knowing what I know now, I may have taken some taped pliers to it instead which could have given it more of a shot of being safely removed. Stuff happens though and I’m just glad it wasn’t a more rare and expensive lens and really just be extremely careful with lens vise tools, they work but can do real damage if taken too far.
Nice, thank you Mathieu!
When i was a kid and had my first SLR, i managed to use a 75mm Projector lens for protraits and adapted it in quite a similar way as you did. I used a paper roll, in which the lens did fit. This was in ca. 1974.
Greetings from Frankfurt am Main - Andreas
It's so great to see someone who actually cares so much he fixes this beat up old thing. Love it.
PS: I loved that lens vise and I never thought such a thing even existed. I thought you were going to have a hard time fixing that dent, and then this tool enters the scene lol.
The biggest factor here is the complexity of the lens, and I think as a rule it might be best to stick to primes for this reason. I did this with a Nikkor 28mm f2.8 AI-S that has 8 elements and wow that is probably my limit. However, it's my favorite lens to use now and it came with a Nikkormat EL that cleaned up equally well and I should consider using one of these days.
First, I love your channel and style. I have a love for vintage lenses and have amassed quite the collection. I find them so much fun to use. This lens was incredible though. Unlike anything I've seen. It gave the footage such a dreamlike quality and really changed the mood. Incredible job on the restoration as well.
I love vintage lenses. I recently picked up a zuiko 50mm 1.4 for $26. It was/is in a real state. Looks likes its been through a war. Covered in bangs and scratches, the rubber ring is missing and the lens is scratched but the important thing is it doesn't show on the photos. It has a beautiful, creamy, dream like quality to it.
The photos with the fungus still present reminded me of old faded photographs. Actually kind of liked it. Restoring it is absolutely the right move though.
Would love to see more lens repair videos, specially how to deal with lens' coatings. Also, your tool list in the video's description didn't include the lens vise tool you showed on the video (some else in the comments asked about it).
Beautiful work! It's great to see an old lens "shine" again, close to it's original glory.
Outstanding video and lens restauration project. Thank you for sharing this. Keep up the great work!!! 👍
Great video Mathieu with a great result!, I think it's always amazing to see what can be done with old and much newer lenses when they have a lot of Fungus. And I'm also surprised what can with just Hydrogen Peroxide 3%. And there are so many interesting cheap (or expensive) old lenses out there that can be adapted to new camers, and in that way get really different pictures with a lot of nice bohke.
best regards Kenneth
I waited 12 years for this video. Thanks!
Hope you enjoyed it!
the fungus waited even longer.........
Impressive! Your patience and skill paid off. I am inspired by videos like yours that reject a throw away old items culture.
That was nice to see with how much passion you went into cleaning this lens. Well done. 😄👍
Thanks a lot
I love the ring you printed, that was an awesome idea, it’s great that you are saving this beautiful lens.
Thanks so much!
Nice work!
What a big difference of before and after, thank you for sharing 🎀
The youtube algorithm thought I would like your video. It was right. Wonderful subject matter and execution of your project video. I learn a lot from content creators like you. Well done.
Glad you enjoyed it!
I have always had a respect for the folks that made these sort of things after spending long hours talking with a technician's that ground lenses for numerous uses. One of my favorite philosophers Burauch Spinoza spent his quiet life's end grinding and polishing glass for the early telescope's that brought the first Astrologists into conflict with the Natural Scientist of the time.
Excellent video Mathieu... very informative. How do you record the sequence and correct positioning of the various lens elements for correct reassembly?
Really interesting, informative and useful !! Thank you, your channel is exceptionaly interesting and helpful !
Amazing work with the lens!
Excellent !! Many thanks for this !
Woahhh keep on uploading the good stuff!
That little lens sucker tool is cool!
Fantastic video and process!
And very brave to handle all without gloves :D
C'est un projet magnifiquement exécuté. Félicitations pour cet ajout à votre collection !!!
that is actually amazing
I really enjoyed this "almost gone" lens
The lens was probably rated Excellent ++
wow you got all the tools for cleaning!! very nice!!
Bravo et merci pour ces précieux renseignements.
Loved this. Seeing this is pretty inspiring. I feel there’s an art to giving old things a second life when they seem like they were non functional. This makes me want to give this a try in the future if I come across any cheap lenses that I like

You did a great job! :)
Have a good week!
Great information, thanks for making this video.
Nicely done. Projector lenses are so cool and great candidates for fungus repair since they’re often uncoated and dead simple to disassemble. I like acetone too but worry about it on camera lenses because of the coatings. If you’re still looking for projector lenses I can recommend the Lomo 35KP 75mm f1.8 - I have a few if those Lomo lenses adapted to full frame and the 75mm is stellar among them. Keep up the great work my friend.
lens coatings aren't paint, they won't dissolve in acetone.
How do you mount those projector lenses?
@@Tricklarock The easiest way is to buy a 62.5mm to M42 adapter on eBay, and a M42 focussing helicoid for your particular camera mount.
@@timskinnercanada Thanks!!!
@@creepyloner1979 umm yes, they can and actually do! Acetone eats through lens coatings faster than glue or paint. you NEVER ever want to use acetone on a coated lens.
Manny immediately apply a UV filter to a new lens in order to protect the front element. However, the principal enemy of fungus is UV light. By blocking sunlight, others things being equal, this natural enemy is eliminated. As for me, I store my lenses without any filter attached and pointed in the direction of my office windows in order to maximize exposure to sunlight.
love love love this thank you for sharing xo
Amazing video. Thanks for making this.
Świetna robota brachu.
you bring it back to life！amazing
I have a Orion refractor with fungus in the objective. I'm concerned about the coatings. Will the soap or the peroxide wash out the coatings? Is there anyway to get rid of the fungus and prevent from washing the coatings out?
Bonjour, merci beaucoup pour cette vidéo, ja’i un superbe 50 1.2 de Nikon avec des champignons, de quel matériel aurais-je besoin pour le nettoyer et démonter/remonter? Merci d’avance!
Fantastic work, I’m starting a project on some old Pentax lenses that I could not afford if they weren’t fairly wrecked.
Great job. The final result videography is impressive. I do not doubt the price of the lens & you did an exceptional restoration job but IMHO, my cheap Chinese adapted Fujian (or Fujinon) 35mm f/1.7 CCTV C Mount Lens has a very similar look to the footage I see here, minus lots of CA that this expensive vintage lens has none.
Like always a very interesting video but I have two things to throw in.
Did you reassemble the duplet that separated? Its actually not so hard to do if not just buy some optical adhesive (if you want I can send you the product name).
The black paint is not as easy to correctly replace as you might think, the base should have a quite similar refraction index as the glass, for small patches and defects there are certain sharpies that work great (those have particles in the paint)
And did you ever think of rehousing/re-barreling some of your more interesting lenses? Some of them could be really interesting with a real aperture and a focusing ring
Nice work!!!
Doesn't seem that the fungus had the opportunity to etch the glass. Beautiful lens and very sharpness in the middle and softness on the edges, great portrait lens for sure.
I had adapted a pistol scope for a scout rifle, so no magnification.
I took it off and it ended up in the basement and one year the AC died and humidity in the cool basement caused everything to get a little moldy and by the time I noticed the scope was moldy.
I treated the outer metal as if it were rust and it cleaned up fine but the glass still has a little mold on it.
I'll try the peroxide and acetone to see if it works.
congrats with 300k!
Thanks a lot John
Forgot the mainland European use of a comma instead of our (UK) period as a separator and thought €600k! What?
Amazing what can be done with patience, a few simple tools and peroxide! Well done.
Nice job!
Wonderful work! What is the white liquid you used to clean up the name of the lens?
Отличное видео, всегда приятно смотреть!
Merci ! J'avais besoin d'infos à ce sujet !!
So good! Great job!!
Glad you like it!
Reaaly great video! I really like the new life you give to all these vintage lenses! I think I will give another go to my old m42 lens, I must buy an adapter for the x-mount (I used it on the EF-M before).
I have a question for you and all your community, the outer ring of my Canon EF 100mm macro (non L version) is broken and I can't find where to buy a replacement part, is there a shop in Europe that has this kind of parts? I don't want to send it to the official repair centers, because they will bill me at least 100 euros for a very simple repair.
Very Nice 👌👌👌
This is very important information... Thank you 👍
Your title makes it sounds like you're cleaning "with fungus"
Fantastic job!
This is Great!! Could you tell me which Helicoid adaptor you used? Thanks!
It was terrible the general condition of the lens but the restoration process and the final result is really impresive 👌🏼👌🏼🙌🏼🙌🏼🙌🏼🙌🏼
aweesome video! thanks Mathieu
Thanks a lot
Thank u for this ❤❤
How do you adapt projector lenses to cameras? I would love to try using projector lenses.
Nice Job.
Bravo Mathieu vraiment sympa de partager.
Amazing! Nice job. I was of the impression that lenses needed to be calibrated if you remove/adjust the elements? :)
Fantastic video, so interesting.
Thank you :)
I do have another question. I own a Spotmatic with a number of 42mm screw mount lenses, and a Pentax MZ5- N with a number of the Pentax bayonet mount lenses. These are still in regular use. I also have a Nikon D3000 DSLR which is also in regular use. Where can I get a Lens adapter to fit my 42mm lenses to the D3000 ? Your help would be very much appreciated. I live in South Africa.
ZWIEDZAJCIE ZOO😂😂!!
zoo grzybów ?
Great job on the cleanup!
Realy nice work. Wich concentration of H2O2 did you use? 3%?
And how long did you keep the lens parts in the liquid?
I really need to get some of these really weird lenses. My old Pentaxes and Helios are cool but hot damn some of those shots in the opening are insane!
The correct way to use a 'lens vice' is to clamp it with the flat outer face opposite to the filter ring defect then tap that flat 'hammering face' gently with a copper face hammer or similar, pushing out the dented rim without putting pressure on the other side of the barrel. You work the clamp by loosening and changing its position and then tightening and tapping till the dent is gone.
that is an entire fungus farm there... :O
Hey, I have a small question, doesn't the acetone attack the coatings on the lens?
hi sir. a good day to you. I just have a question. I have an old lens that needs to be cleaned and have some fungus in it. I would like to try and clean it by my self. Do I need to clean it in a so called "clean room" or a regular room in my house will do? Thank you so much for your videos. More power to you.
Thanks for the video. Whats is the tool that you use to adapt the lens to the camera? Regard from Argentina.
Hi Matheiu, great channel ! How long did you leave the lens in the hydrogen peroxide solution and then in the acetone solution?
in the hydrogen peroxide you can leave it from 10min to 2 hrs, but the acetone solution should only be used very carefully and with lenses without coating ,
Hello , good video and good job . Does the acetone not destroy any possible coatings on a lens ? What was the white product you used for restoring the name on the lens ? Thank you .
the with product is just basic white paint.
acetone is not safe for plastics, if you are not sure about the type of coating, i would test with other products first
You should invest in an ultrasonic cleaner. Great video
Thanks for sharing your knowledge. I just noticed a small 5 mm ring on my lens and was looking around for professional help.
My expert friend discouraged me from opening the lens as he claims I will never be able to put it back. So far I have seen 4 videos of lens cleaning and no one talks about the likelihood of misalignment. Today I gave me 24-105 f4 a good sun treatment after covering the non infected part. I would like to send you the picture of the fungus. Some people treat with hypochlorite and some with ammonia. I want to know what you would advise me. Thanks a lot.
Hydrogen peroxide works great and is easy to find
@@MathieuStern
Thanks for your kind response. I will go with the peroxide which is available in pharmacy. Would you recommend soaking in peroxide over to ensure that it does not come back.
Master work
@mathieustern is that a handmade custom focus puller or where did you get that??
Brilliant, I could do with sending you my Fuji 50-230, I broke part of the bayonet, bought a replacement but it was a cheap one and I’m sure it advertised as having electrical fittings in place but they’re not and I’m a little scared of doing it myself 🤣
Is there any helicoid adapter WITH aperture control? I mean, and adapter with aperture blades and a ring to control it
Nice one sir.
Adorable job. So acetone completely removed the balsam residue. But when reassembling, you didn't replace the balsam, or did you use any other trick for a better refractive index? Just curious.
I just want to thank you for explaining to us, layman, what the "glue" was used for!
Awesome!
Incroyable ! Très beau travail, ça donne envie de nettoyer mes vieux objectifs
