The hardest part is wiping the lens clean
DAMN TRUE!
lol so true. i got more dust debris when assembling helios 44-2 😅
Definitely.. the number of times I put one back together and notice a big greasy finger print or annoying piece of lint only to have to take the whole thing apart again!
That’s 90% of the time used when disassembling a lens. Even when you think it’s perfect you find a bunch of dust only after putting in the second to last screw 🥲
I’ve got an 85mm lens that needs this on the rear of the front element. It was a good deal, but I’m not wild about it so will probably clean and sell. BTW, that whitening on your black rubber focus ring can also be cleaned, either with a clean dry brush (toothbrush, etc.), wiping with a very slightly dampened microfiber cloth (mild soap and water, hydrogen peroxide, or isopropyl all seem to work). I once tried to haggle a guy down because I said the whitening made the lens look old, he just cleaned it up before selling it and got his asking price :)
Great tip for the whitening! I have that on a lot of old lenses and didn't know what to do with it.
@@snappiness Armor-all or any other car interior protectant works way better for this and lasts a lot longer. I use it for the rubber on old Maxxum lenses and it lasts at least months.
This point,I'm about to make is one of theeeeee most important. Before removing any lens element from a lens take into consideration,1 it must be replaced exactly as it was ,meaning a mark or piece of sticky tape on the lens outside surface to re align its orientation when re assembled. So let's say for example you place a sticker on the front element at the top in relation to being mounted on the camera.Then when re assembling, make sure the sticker is at the top when returned .If not done this way .Your perfectly clean element is now decentering your lens .as accurate as you may think these units are made they are culminated and balanced to project a perfectly cantered left to right up and down projected image before passing qc.Its easy to warm the tape from the outer element after assembly and clean with reccomended fluid such as lighter fluid ,which I reccomend .50 years tinkering makes life a great classroom, but never a courtroom .Good video .we're all still learning .
Shouldn’t you also clean the plastic part that touches the lense?
It'll be cleaned the next day...why do everything at once?
Two comments:
1. Cannot buy clear ammonia in Australia because they are scared it will be misused. You can only buy cloudy ammonia which means it has some soap mixed into it.
2. I like the use of hydrogen peroxide, quite clever to eat away at the biomass. I wouldn't have thought a weak acid and strong base would stay stable enough, but it looks like the two sit in a nice little sweet spot with their pKa so, cuddos.
I have 4 lenses that I bought 2nd hand and they all have this fungus in them. Thankyou for uploading.
Can't you use ethanol ? It's used to clean microscopes
Ethanol or isopropyl has it's place and will be streak free (if there is no fragrance added). Ethanol is slightly acidic which means it isn't very good at breaking down fats. Ammonia being caustic will deprotonate fats and turn them into gels, which can deal with fats that are quite literally adhered to the surface.
The reason you wouldn't use ammonia on microscopes is because it's particularly annoying to work with, for both the fumes and it's propensity to just gas off leaving you with smelly water. Also, corrosion.
I thought you couldn't mix the two?
@@xhivo97 not sure what mix you're referring too. Ethanol and ammonia? Never mixed it and despite being a chemist I couldn't say for certain the result (without significant study). Ethanol and peroxide? Never mixed it, same as before.
Peroxide and Ammonia? I wouldn't have thought to mix them, but seeing it done it highlights the pKa and equilibrium of peroxide keeps it stable long enough to be usable.
IF you mean to say "I thought it was bad to mix" you may be thinking of bleach and ammonia, which will produce chlorine gas. I've never mixed them but I have mixed urine and bleach by accident. The ammonia in the urine was bad enough to be an issue and is a few orders weaker than what you buy in the shops. I would hate to imagine the problem you'd have on your hands if you mixed cleaning grade ammonia with bleach.
@@HaydenHatTrick I'm not a chemist and I didn't bother to do any proper research but I asked Bing AI (which can often get things wrong) and it thinks that at low concentrations (presumably either or both) it's safe but the more concentrated they get it can be dangerous.
This was very thoughtful, and pointed out some good stuff. Thanks for taking the time
I have an efm 15 to 45 experiencing the same issue..have to get mines clean... awesome vid dude
Did you tried to clean it...Iam having the same problem with my EFM
balls of steel. Mad props!
Just did this 50/50 mix with all 10 optical surfaces of a heavily infested SMC Takumar 1:1.8/55, but did it in a cheap ultrasonic jewelry cleaner. Seemed to work great. Fungus is gone, but it had been there long enough to leave micro-irregularities in the surfaces. But the lens is much better now than it was. The hardest part was wondering why that one part wasn't fitting right (to only remember, oh yeah, that's NOT how it goes).
Good work!
you should also mention that using Sun light rays directly on the lens also helps but that's a very slow process.
Dude...I am impressed
I buy and rebuild a ton of vintage lenses...some of them with extremely severe fungus growth in them.
I've found that just 5 min in higher concentration hydrogen peroxide works great.
Don't need the ammonia.
Final clean with Zeiss lens cleaner.
If you have fully sealed lenses or even if you take an older non_sealed lens (depending on the design) and add o-rings to seal it, you can reassemble it in a nitrogen purge box and avoid any optical changes in more extreme temperatures and fungus won't grow in it ever again unless the seals fail.
What an incredible skill to have. Where can I learn this?
Fungus gone, but isnt your lens coating gone as well?
Coating will be gone eventually, but it's the price of resurrecting an old lens from the fungus. Most people are okay with that and using it with caution 😊
Store them with silica gel water absorbers.
It doesn't work... I know...
@@hugobracamontesbaltazar It works but you kinda have to use a large baggy of them. Once the moisture is inside tho... Then yeah, you're gonna have to dismantle it.
@@Ipsissimus the fungus will then be dead and make the lens foggy i guess?
I have a nikon 70-200 2.8 with mold on every element. Bought it cheap that way. Was going to clean it but MY GOD does it make a really awesome bokeh effect.... so I just leave it like that 🤣
Might get some spores on your camera body and then get transferred to other lens and grow
@note2tee been using it for 5 years this way. I killed the mold on the forward element with alcohol and peroxide.
@@note2tee the spores are in the air already. Fungus spreading is a long disproved myth.
Treat the lens with UV-A light (caution) for some hours… it should kill the fungus and the spores but left the mycelium that produce the bokeh effect that you like.
@@note2tee😂😂😂😂😂
What started to me as a fun side project (adapting a Mamiya Sekor 38mm f/2.8 from a Mamiya 135 ee on a Sony E mount camera) made end up here, looking on how to clean fungus on a lens and also the internal segments because they appear to have stains of something as well (it's a 47 year old lens from a camera that belonged to my grandmother, it surprised me that it was not worse than it actually is)
I'd be reluctant to do that with today's modern lenses due to the complex coatings on them. That mixture of NH3 and H2O2 could damage the coatings then you'd ruin an expensive lens.
The fungus Already ruined it better try then throw away
Si es tan nueva no deberia entrar hongos
Mild soap could work better but stay away from isopropyl alcohol
“All clean”
Huge dust particle: :3
Excellente vidéo, très utile pour moi. Merci beaucoup !
This is like my film photography youtube channel because not only do they both feature camera lenses, but my channel is also growing fungus from the stagnation in viewership
BRO GOT A SIGMA CAMERA
I do, a sigma sd10 and sd14!
I’m gonna have to do the same thing i just received a used tamron 200-500 lens today and it came with fungus 😮
Disassembling took me 10 mins. But putting it back wiping away dust on the lens element took an hour and still looks imperfect. 😂
yup me too lol Buying a really nice micro cloth and rocket blower has really helped, but still find little greasy prints or dust everywhere even with gloves.
Sunlight also surprisingly works wonders
Yes, but glass stops UV rays. I don’t know if it would kill fungus on the inner elements.
The problem is not how to remove or clean the lens. It's how to put it back. You have to be extremely precise.
Can you do a comparison of the same lens, cleaned with the solution above after the elements are put back in? I want to see if there’s much visible difference without the coatings
I don't know how to do any of this; so I only use a 50mm f1.8 RF on my R6II. If it gets fungus, I'll throw it away and buy another one.
Wouldnt ammonia damage lens coating?
Nice!
Fugus says ”SOS“
Surprised to see this old lens on the interwebs. My focus ring also looks like this lol
They seem to all develop that white stuff. Someone told me something I can use to make it look like new but I forgot.
I wouldn't have the equipment to do this. TFS xx
Have you made full length videos about doing this?
Nice tools...
and tip how to store lens correctly? dry and shade and cool?
In a place with low humidity, to keep this from happening.
@@snappiness if i keep them in a fridge is that a bad idea 😄
Dry cabinet
Just wondering, how about the lens performance after that? Does it affect the coating as well?
It will not affect the coatings, and the lens will perform as new. The exception would be if the fungus is extensive and has itself eaten away the coatings, in which case I've seen it where after the fungus is gone there are lines without coatings. But that's still much better than major fungus. In this case, that little fungus near the edge of the lens would not realistically affect performance, but wanted to clean it anyway and stop it from spreading.
That's not enough, the fungus reproduces via the spores. The object must be completely disassembled and cleaned, otherwise it will keep coming back.
If Possible Please Make One Video How To Open Nikon P1000 Camera Lens??? Please
What is the name of the special tool they use to remove the second ring?
Lens wrench. As in the video, the tools are linked in the description anyway.
How do you prevent dust entering the tube when you assemble it back?
missed a step post solution. You rinse?
I'm just here for the music.
That name sigma
you make it look so easy, I'm trying to open mine with the rubber tool but with no success!! is there a trick? I have the SIGMA 56mm lens for E-mount
It was tough for me too. I was pushing and twisting for a few minutes before the clip you see in the video 😆 no big trick, just trying to apply equal pressure across all sides.
@@snappiness thanks! So I will keep trying 😃
Nightmare type situation
I need this done on my sigma 24/70 for Sony emount
To be honest, bring it back to the shop you bought it for repairs. That lens so so expensive you probably dont want to risk it!
Nice
I don't have the tools to get the glass out hopefully that doesn't happen when I get a camera
That doesn’t strip the coatings?
luckily it was just the top element.
Yes, the front few elements are by far the easiest
@@snappiness i have an old off brand FD lens and it had some mold. It was a few elements in. Putting that thing back together had me ripping my hair out
I hate fungus so much. So freaking stupid how easily it can grow.
Thanks I'd not risk dust and more spores getting in unless I had my own clean room. A bit of fungus has minimal effect on the images.
Pretty lucky my humidity almost never goes higher than 25%
Tool names please
I asked a Canon official repair shop about treating fungus and they implied it would come back. Perhaps they don't use hydrogen peroxide etc. Are there any UK people that do this service?
🔥🔥
Is it possible to clean a tamron 17-70mm f2.8 like that? I didnt do it before but it got much dust inside. Or maybe you did it already and have some bid of that?:D
How do you clean dust from inside your lens? I got dust in a few of my lenses and thought about cleaning them myself.
Dust is a tricky one, because unless you're in a dust-free area and extra careful, you'll probably end up introducing more dust than you removed by taking apart the lens. I wouldn't do it unless the dust inside the lens is severe.
Won't the peroxide eat away any IR type coating on the lens?
Cool but what's the soundtrack?
Take a macro shot of it
Where can you buy that tools that opens the front glass??
What is the rubber tool called?
This is a great vid!
But the geometry dash font killed me 😭😭
What about coating of the lense??? Is it gone???
Come on, did u at least take a picture with it on?
I am also having an issue with a fungus growing any suggestions on how to deal with. Oh yeah the fungus he’s 16
dang.. how long did it take the fungus to get that big?? o.o
Can i ask how did the fungus get there?
moisture vith some spores
Yeah, moisture can get in there for various reasons. It happens a lot in humid environments, but could happen for other reasons too
It will be good to put that lens under some strong UV light or at least on sun.. it will kill the rest
Where I can find those Toll and and chemicals, do we have to join to see the tools and chemicals you use, like to purchase them and try it my self on my lens
I have links for the tools I use in the description (affiliate links). The chemicals you can buy at most grocery stores.
Is there an o ring or seal that needs to be replaced?
can't see list of equipment used here
It's in the description, but RUclips has made shorts descriptions really hard to find
Really awesome, I’ve never seen this process done, very interesting to see 😮
What if lens is not removable like sony zv1
I don't have any experience with those, so I'm not sure...
I cant find the link for the tools....
what did you used in taking out the lens from its frame?
What if it’s between the middle elements.?
How long in the bath? What ratio for the solution? I has this really fast full frame 50mm,....
Edit,... Dammit YT, play the whole video, not a center crop,...
The guides I follow have a 1/1 ratio, but it's really not terribly scientific. I've read people just using hydrogen peroxide, and some just ammonia so I'm not sure. This works for me though. And the soaking time I just roughly estimate based on severity of the fungus. I'll take it out periodically and check to see if it's removed everything or not.
when you use a suction cup to remove the lens, wasn't that lens glued and don't you need to reglue that on reassembly?
The only elements I've encountered glued before in a lens would be the very rear elements. These front ones are not, some of them are just flush. But there could be other types of lenses with more glued elements, I'm just not aware of any.
@@snappinesswhat do you do with the glued rear elements? They are held on by plastic that is actually part of the rear element housing.
@@snappinessi don’t understand the suction part. What do you suck?
Where is the link????
How about alcohol only?
Soak in what solvent?
does this affect the coating?
Where can i buy all those cool tools
Links to all the tools in the video description 👍 hope that helps
@@snappinesscouldnt find the links bro
What's the first tool you used? Not seeing it in the drop down list
Hmm I am having trouble linking it, but it is in my description linked (unless that's not showing up for you). If you search for rubber lens repair it'll show up.
I don't have that remover you have sad 😢😢
How does this even happen?
Sony FE 90mm 2.8 macro😢
Is the chemical reusable or need to throw away after lens is taken from it?
given peroxide is a weak acid and ammonia is caustic, I'd say it has a limited use life. Also, the ammonia will evaporate out of the solution and does not form an azeotrope... so ammonia on it's own is not really reusable. That said, if you had multiple lenses ready, you could probably clean them all in the one solution but it's hard to know when the solution will get dirty enough to leave streaks.
People see the sigma in the middle😂
what is the name of the opening key?
What is the song playing called? Shazam doesn’t return the right song
What was the tool called at the beginning???
If you search for rubber lens tool you'll find it. I have a link in my description to the one I bought.
Cant see the tool descriptions
If you're on mobile there's three dots on the top right. Click there and then one of the options is the description.
What are the tools?
I put the links to them in the description of the video. A spanner wrench, suction cup are the main ones.
Just used eye cleaner and never came back.. but hey.. it doing all this make you feel better.. go for it
have you opened a Samsung lens before?
You should have used SpongeBob's "30 minutes later" with Jaques Cousteau accent
Would've been perfect :)
