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.
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!
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.
@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.
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.
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.
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
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.
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).
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.
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
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.
Very impressive, I would never have thought that you could breath new life into such a badly degraded lens. Well done and thank you! Kind regards . . . . Andy in the UK
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.
@@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.
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.
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.
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?
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

Excellent video Mathieu... very informative. How do you record the sequence and correct positioning of the various lens elements for correct reassembly?
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.
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.
It would be interesting to know where to find the tools you use and at what price. Wouldn't a strong UV light lighting not be valid to eliminate fungus infection only?
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.
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.
@@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.
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
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.
Bardzo dobra robota. Te grzyby na soczewkach o których piszą to nie są czasem te super powłoki które po latach się utylizują i rozkładają pod wpływem światła UV ?
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.
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 ,
Excellent video and thanks for sharing this. Mind if I ask about a lens I have that I think has fungus? I have a Meyer Primoplan that I think has little bit of fungus that I'm scared of bringing near my other lenses....any chance you know how to disassemble it and/or know of who I could send it to for a thorough de-fungus cleaning?
hello, if your scared to put it next to your other lenses, just put it in a zipper plastic bag, like the ones for sandwiches, if you want to clean it , you can try it yourself as it's not an electronic lens, but sending it for cleaning to a pro will cost you more than the lens worth
Incroyable! J'ai utilisé du peroxyde d'hydrogène pour nettoyer certaines taches internes (je pense causées par l'humidité de la plage). Et ce fut une réussite ! Merci beaucoup pour votre précieux conseil !
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 🤣
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.
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.
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
Wanted to ask the dame, cause it's not on the list of the items used. Need one too for some of the vintage lenses I own. Thanks for the person replying here . Will try to find it online!
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.
A question on the black marker you used. I assume the black is to not reflect light from the sides of the lens? How do you think using something like Black 4.0, something that reflects almost zero light would work? Maybe I'm wrong on what the black is for in this case.

lens coatings aren't paint, they won't dissolve in acetone.
