Helios 44-2 fungus: Take between 8 and 10 lenses. Remove front and rear element. Scarpe the fungus into a plastic or metal container. Add a little garlic and butter. Heat the fungus on a low heat for ~6 minutes. Serve with toasted bread on a vintage lens cap.
You have gone to the trouble of telling us NOT to touch the chemical, then you hold the lens with one glove and the cloth with acid in the other without glove...but, Thank you for the very interesting video ! Keep up the good work.
Hello! I know you specialise in Russian lenses, but can you give me an advice on how to clean the rear element group of a Super-multi-coated takumar 50mm f1.4 with a m42 mount? There are no screws on the back. I’ve searched all over the internet for some instructions on how to do this but nobody seams to have tackled this problem until now. Thanks for the great videos, they are really useful, keep up the great job!
In my lens (Industar-61 55mm) The first frontal ring turns for 90 degrees and then gets stuck and I cant get it out. I even tried brute force. Any ideas how to get i out?
hi, thanks for the very informative video, can I use the same chemicals on newer lenses ? will it affect the coating for newer lenses. I want to clear out the fungus of a new Samyang and Tamron lens inside the lens.
Hi, is there any chance for you to make a video showing all cleaning process for nikon 80-200 f2.8 push-pull? I have one of these and I need to see a video step by step before. Thank you!
In case it helps, ~25% ammonia is the same as ammonium hydroxide, and is often branded as just 'Ammonia'. Ammonia is usually found in construction and paint stores. You wont mistake it for pure ammonia, which is a gas at room temperature.

Exactly
Thank you for showing us how to properly clean this lens
thanks! it helped me not just to clean the lens but reassemble it the right way!
Very impressive! I find lots of lenses with fungus inside, I may try to fix some of them with this method, thank you!
Thank you for making this video, my front lens element was rattling around and i learnt i could tighten it down because of your video
Glad it helped!

Thanks for the great videos, they are really useful, keep up the great job!
i have no experience with japanese lenses, sorry
I understand, thanks for the reply!
GREAT TUTORIAL thank you!
Shouldn't the individual lens elements be marked on the edges so as to preserve their original collimation when reassembled?
No, it is not so sophistically made. This is a mass production)) 3 mln of pieces were built
@@RetroFotoHouse I see, thank you.
WIll try on my lens soon. 98% alcohol and Ammonia Hydroxide
Thank you for your skills .
Cool manual, thank you !

this video is about helios 44-2, not industar...
@@RetroFotoHouse Yeah, but this problem can occur with any lens since it's just cross-threaded. At least that's my guess. I don't know.
Should you also clean the retention ring? Fungus may still reside in there.
yes, that's a good idea
Привет. Подскажи какую жидкость используешь для чистки линз?

i can't say about new lenses, my specialization is vintage lenses.
12:20 ouch!
I was all gungo ho to give it a go. Now Im not so sure lol.
despues de eso nunca màs volvi a limpiar lentes, rayé un lente
thanks for showing.
Excellent Job! I couldn't find ammonium hydroxide in my country, is there anything else I could use to remove the fungus? thanks!
frankly speaking i do not know. you can try pure alcohol
@@RetroFotoHouse Ok, I will. thanks!
Hydrogen Peroxide is a good option too.
Gracias 🎉🎉
Awesome job, thanks for sharing. How concentrated is the ammonium hydroxide you used? Will 10% concentrated work? Thanks
Hi! Yes, it will work for sure
Hi!
How many percent have your ammonium hydrooxide?
@@angelraphael5233 3% fine leave elements submerged for 5 mins.
Ty
Damn good work, thank you for this.
Hey there I have a Helios 103 lens but cannot find an adaptor for cannon edit. Help please... this was a good tutorial btw
will the ammonium hydroxide effect coated lenses?
No, it won't. It affects only organic substances
@@RetroFotoHouse Thank you very much : )
Does lighter fluid do the job?
no, i don't think so
petrol..is the best..never had any problems.
Hello. Does the ammonium hydroxide damage the lens coating? Can hydrogen peroxide be used to remove the fungus? Thanks 🙏
Hi!
No it doesn't
Hi, is there any chance for you to make a video showing all cleaning process for nikon 80-200 f2.8 push-pull? I have one of these and I need to see a video step by step before. Thank you!
Hi, no i'm not familiar with this lens
Russians make DIY servicable equipment, as Japan did once upon a time, but then went on to non DIY servicable or throw away items.
How do you avoid dust floating straight back in the lens as soon as you clean? Do you have any kind of extractor going above the work area?
No i don't, but few dust specs doesn't influence image quality at all
Hi there, If I can't find Ammonia Hydroxide, can I use Hydrogen Peroxide?
Yes, and also alcohol. They don't damage the coatings.
Добрый день! Можете дать ссылку, где покупаете салфетки ( в чёрной упаковке)?

Hi, ammonium hydroxide is hard to get in my country, can alcohol kill fungus as well?
In case it helps, ~25% ammonia is the same as ammonium hydroxide, and is often branded as just 'Ammonia'. Ammonia is usually found in construction and paint stores. You wont mistake it for pure ammonia, which is a gas at room temperature.
Yes, you can use alcohol or hydrogen peroxide. No problem with coatings on lenses.
Are these lenses radioactive?
Hello, will it work the same with helios 44 13 blades version?
yes, it will
Hi! it possible in this version reverse it front element?
normally not, as there are no enough thread on front ring
Где вы берете такие салфетки?
Hello ;) Could you tell me what is this tool in 2:38?
this is ordinary forceps with pointed ends
Hi, what type of cloth are you using?
Any microfiber cloth is working fine
What to do if you forget the way each lens was facing, when they are not symmetrical?
2 front optical elements should be with opacity to the top, 2 rear-with opacity to bottom
Hi.. What you call those tools?
calipers, lens wrench, pointed forceps
Есть ли на русском ? Что делать если зажимает переходник фокус ?
4:18 как это называеться ?
Mmmhhh fungus 😛😛😛
what alcohol is that?
pure ethyl medical alcohol
@@RetroFotoHouse Can I use the following Composition:
ethyl alcohol 96% v/v
Partially denatured with cetrimide of 0.25 to 0.3% m/V.
does ammonium hydroxide also remove the lens coatings?
no, it doesn't
thank you, I think I'll use ammonium hydroxide as my main cleaner now
12:21 ouch. my worst fear when doing stuff like this.
Did he slip and scratch the rear element
no, it didn't
12:21 ouch :(
用威高的清洁布就离谱，还是中文的
hello, what percentage should the chemist have?
