- In this video I shows how you can clean out the dust behind front element.
Sigma 24-70mm f/2.8 DG DN.
You will need "ph00" screwdriver.
I have used white stripes only for mark original position of parts.
ps.
Don't panic, a few dust particles not affecting your photos quality.
Just bought a used Sigma 24-70 f/2.8 Art and found a decent amount of dust behind the glass - thought I was screwed. Thanks for the video and helping me avoid paying to have it cleaned!
Pretty sure they clean it for free. I would get it professionally cleaned then sell it lol
This costed me $500 when I sent my lens to Sigma to clean the dust. I had no idea how easy it was to do it myself. Thanks for this video! Also nice to know that Sigma lied to me and told me my front glass element was faulty when apparently a lot of these lenses have this issue.
Bought this lens last week and my first job was in a VERY dusty warehouse -- it naturally breathed in a tonne of dust and I was freaking out a little. I followed this video and blew out ALL the dust so easily, thank you SO much. Will happily do this as and when I need to. Sucks about the dust issue but this is a great fix and still a great lens to choose over the GM and Tamrons. Thanks!
Was yours the updated one with the serial numbers beyond 5504xxxx? Is there any differences in the components from the video?
They say they updated the seals, but if the components of front element are the same I don't see how they manage to solve the dust problem. And I'm getting mixed messages from other forums.
THANK YOU!!!! My hero, my lifesaver! It totally worked! I had some difficulty putting it back together because of the tiny spacers not lining up at first, but finally found the solution. I need to do the same for the Sony 100-400 mm F4.5, but can't find any tutorials on it.
the answer from Sigma tech center: the repair and cleaning is free, the sigma fix is putting a ring of felt. hope this is helpful.
Thank you for this video! I don’t have this lens, but the Leica 24-70mm F2.8 (Japan) that has been suspected of being this Sigma lens in a Leica body. Well guess what? I had the same dust issue with the “Leica” and interesting enough it’s front element is removed EXACTLY like the Sigma. It looks identical, including the ring that you pry out, the screws, and even the spacers. Mine only had one spacer total. So I was able to clean it out, thanks!
Don't set the dust ring down on the adhesive side like I did on a piece of paper!!! Great tutorial, thanks!
wow awesome man. I literally got my 24-70 Sigma for Sony FE and got 1 speck of dust in it recently. This video is a godsend. Now I just have to work up the courage to do it myself LOL
If I were to buy the lens now, would this problem still be there?
@@oklokih not sure
@@oklokih $1,099 for lens with dust issues?
The problem may be this ... I read a lot of things about this lens in several forums, and I saw all the cleaning videos about her on UA-cam. And I also saw some reviews talking about that some users removed these metal parts, and they had no more dust problems. I realized that in one of the lenses had only one piece of metal, in another video they had two. I believe that these parts are to calibrate the front element in relation to the rest of the lens, and they probably leave spacing for dust. Anyone there who has removed these pieces noticed some depreciation in the quality of the photo?
Hello, is there any update in regards to removing those metal clips ? Thank you.
Great video, I guess this is a common problem with this Sigma lens. I just bought a used one and I thought that I inspected it carefully but I recently noticed dust inside the lens. I'll give this a try. Thanks for sharing.
thanks - was easy enough to do. shame on Sigma for releasing this lens with this issue.
Man! Mine had marks of fungus, thanks to u they look like new now, THANK YOU!!!!
thanks dude, really easy to do.. sigma uk wanted £160 jeeeeeeeezzz all sorted in ten minutes
Amazing! Thank you so much! My lens got dust so fast right after I bought it. Thanks a lot.
Has the weather sealing changed at all since? If I bought this lens now, would this issue still be there?
@@oklokih Yeah I'm pretty sure it's still a problem
I got mine less than a month ago and I have a noticeable dust inside... 😅
very good, advice. This lens is so fantastic and such a disappointment at once. I had multiple copies with serious issues- very high LoCA, one was super soft when wide open but had no LoCA issues, the last one was fine with some LoCa but I decided to keep it. Couple weeks later I'm still within return period and although barely used, there's already dust inside. Come on Sigma, what's going on- I had some older Sigma zooms which were incredible. Makes me worried about this lens...If I have to return it again, I'll be heartbroken but have to go for tamron on 28-75. It's far from being as nice but at least it has no quality issues...
Same here. I just got my first copy and it seems that it's very blurry wide open in close range, but I researched a little and it seems that this is normal.
There was already dust inside it when I received it, unbelievable.
But I just keep it now and I cleaned it with this very helpful video. I'm tired of being beta-tester...
well who is the real tampon ? in my opinion the on that has bad qc and problems...
@@drakedoggy103 my friend has one and it’s fantastic in every way. I circled through 5 copies probably and each had a serious issue. In the end I settled with the copy which had strong LoCA at longer fd but then the dust entered the lens after just a few uses. So it went back for good.. bad QC or design which is unreliable. I’m surprised to see this from sigma, I like their lenses a lot normally
Thanks, this worked perfectly
hey question: Did you try using an o-ring just below the first sealing ring? maybe that could minimize/fix the dust problem completely?
Do you need recalibration after disassembly ?
very interesting as a video, I have a question about it.... I have a sigma 50mm f1.4 art series, with a mold problem inside, in the rear lens. I don't know how to proceed to get to the lens, and remove that horrible mold.
Great and thanks i was very scary that I needed to send it away. Spend a lot of money I’m gonna clean it myself although I think it’s really crap and cheap because I have my lens two months and it is already full of dust.
Am I tripping or there’s no sound on this video? I tried on my Mac mini and iPhone still no sound
Are you kidding...? Why would the instructions be spelled out if there was audio?
@@SikConVicTioNI’m used to having words in instruction videos due to deaf watchers. So it’s not that far fetch.
Im wondering if the 150-600mm contemporary front element comes apart just as easily? Has ANYONE taken the chance to find out??
Can someone please link me to the screwdriver?
Update: I found it. It's a +000 JIS screwdriver
Witaj. Świetny poradnik. Mam pytanie odnośnie pracy autofocusa, czy w Twoim egzemplarzu podczas łapania ostrości słychać takie ciche stukanie? Mój obiektyw nigdy nie upadł a odnoszę wrażenie - po obejrzeniu filmó w internecie że mój egzamplarz pracuje głośniej niż pozostałe. Czy w Twoim przypadku jest to zupełnie bezgłośna praca silnika autofocusa?
I am curious how you take off the sticker on the glass of the lens without making marks on it...
you should fold the tip
Any ideas how to seal it?
Thanks for the video! Very helpful, is the procedure the same as 24-70 art for canon's mount?
Surprising there's dust since Sigma claims that this lens is, "Adaptable to various uses and photographic environments...In consideration of shooting under challenging shooting conditions, the dust- and splash-proof structure and water- and oil-repellent coating are adopted."
This kind of zoom lens newer will be 100% waterproof because lens have to breathing when zooming in or out. but they could designed it better, this lens (only my feeling) catching dust 5 times faster than my other zoom lenses.
Mateusz Mikolajczyk yes, I had Sony gm 2470 from my company and didn't have any after two years of Heavy usage, but Then bought sigma for freelance job and dust appear after used twice
Thank you ! Works perfectly fine
This should be on sigma to fix. Appreciate the video of course. But no one should have to open up the front element of their lens. That’s just horrible QC
Or no QC. The lens is weather resistant, how is it possible for dust?
great video. worked a treat
how long will it take to collect the dust again? It’s remind me my previous canon 17-55 is usm. Almost the same procedure. Very annoying. Thank you
Pretty lame that Sigma would create a dust magnet lens. They are not new to photography.
Actually how to tighten the ring in the final step ?
just press. ring is stick by double side tape.
@@mateuszmikolajczyk3185 thx , I’d try later
Can someone tell the screw size? I need to buy new ones as mine became stripped when taking them out
Write/call Sigma in your region. Let me know if you find out and how.
Me checking my 24-70mm F/2.8 DG OS HSM Art Nikon after 3 years... indoor outdoor use. no dust phewww. But at least i know how to clean the inside if it might happen to others.
Thank you for video!
Thank you !
I have the same lens and my number is 5538XXX. There are comments that the problem has been solved in 5504 and later series, but the problem seems to be unresolved. Because my lens also has micro dust. i read comments that the problem was solved when did not install 3 aluminum washers. Is this real? Because sigma doesn't seem to have solved the problem.
mine starts with 5558xxx and there is an insane amount of dust and lint hairs inside.
@@jeank3639 When did you buy it, and at what store? I received mine yesterday, from Adorama (NY). The SN starts with 5582.🤞
@@maria.m_pe Good luck with it. You may notice it 4- 6 months later. Some of my favourite long exposures were ruined because of the dust flare.
@@maria.m_pe How is yours holding up so far ? thinking to grab a copy of this
The exact serial number of the fix is 55641775.
I want to buy really this lens but this hall think with dust make me think it twice!
Anyway,if you always have filter on lens ,and you have them always on camera ,one lens not change, dust will be inside again so fast????
I mean, they came dusty from zoom use or "zoom ring" and not from front or bottom ????
I have it(since April), and I haven't had any issues. Just clean it regularly and you should be fine. It's an incredible lens.
@@louisburley1597 How do you clean it? Still no dust issues?
@@Kgomez02_ still no issues. A rocket blower and a proper lens cloth (and your breath) is all it needs. You can use cleaners too.
@@louisburley1597 Thanks! I'm shooting mostly products but I will from time to time use it to shoot landscape and off-road pictures. So, a bit worried for when I do shoot on those days. I just bought it this weekend so trying not to regret my purchase.
@@Kgomez02_ You won't. It is my only lens for a very good reason. Message me when you get it!
Got this Sigma DN 24-70 and shot once with it and have two large specs of dust on the inside front and back glass. Just ordered the Sony prime 24. Won’t shoot my professional work with a lens that has dust in it.
That sucks, why they market it as weather sealed when it is not.
@@spannertechXXI Whats the difference between the lenses before and after 5504xxxx?
@@DrummerJames The ones after are said to have the "updated weather sealing" to fix the dust issue. What I want to know is whether or not Sigma is just blowing smoke. So far no one in the comments replied back when I asked about their lens.
Its ok to clean inside the lens with Zeizz lens wipes?
I recently heard that Sigma is fixing this issue if one were to send the lens back to them.
thank you. are you saying it's a permanent fix?
@@rustyxpr I think it is, but I’m not sure. I’m sending my lens in after the holidays, because it has a few dust specks inside. Hopefully it’s a permanent fix, or I’m returning it and getting the GM instead.
@@DavidStella Do you have any updates? Did they tell you if they fixed it?
@@mexmax1657 I haven’t reached out to them yet because I have some shoots that I plan on using the lens in. The dust I have are tiny and don’t appear in images, so it’s not a critical issue for me.
@@DavidStella Any updates?
Did you use the same screwdriver? Removed black screws no problem but had trouble removing the silver ones.
I have used the same screwdriver.
You don't think this method introduces moisture to the inside of the lens and with a variance in temperature the inside could build condensation?
have a dehumidifier on during this
If this lens is not seal enough to stop dust it doesn't stop moisture either :)
Hey first of all thank you for the video! I followed the procedure did everything but got one problem... the spacers accidentally fell off when I opened the lens and Im not sure were they were supposed to be I have 4 of those.. is there any possible way to find out?
sorry but i don't have knowledge about lens design. Only suspect this spacers are for calibration of location front glass. . my lens has 2 washers. every other copy of this lens may have diferent amount and tickness of spacers. if you mix them. you may lose slightly quality of pictures. but that's just my theory.
@@mateuszmikolajczyk3185 I see.. hope it won’t lose quality.thank for the reply 🙏
Where is the dust going through the lens ? can you put 82 mm filter protection to prevent dust going through ?
It's not helping as the dust comes when you're zooming in or out. It's just a poor design from Sigma and I'm very surprised they're not reacting to this.
@@terryvitanza28 I was thinking to buy this sigma , but I canceled because of the dust problem .....
@@michaelgondokusumo5336 Same thing for me. It's a pitty they're not doing anything about this because optically it's a great lens. But in the long term it would be a really bad choice because of the risks with moisture and fungus developing.
the same for the sigma 16mm????
What size screwdriver do you use to remove the screw?
ph00
Do you know where I can purchase the front barrel? For 24-70mm sigma art ?
Did you talk to sigma in your region? Ask them if they sell parts.

See this. Parts links in description - said he.
Sigma cleaned the dust inside my lens under warranty, I bought it due to the rumored fix but I still ended up with dust inside the lens after only using the lens for 3 days outdoors. Sigma should recall these dusty lenses and install the proper fix. This is the last Sigma lens I am buying you lost a customer Sigma. Not worth the hassle, every time I have to pay to get it shipped to be cleaned also I recieved my lens back and it was scratched.
It’s pretty sad cause this is such a amazing lens, out performing the 24-70 GM (of course the gm is a bit old now), but cost and quality wise it’s so good. Shame. Until they fixed the dust problem I will not buy this lens.
@@thedude1590 I agree image quality is amazing sad this lens is made in Japan and it is so poorly made. A lot of these UA-camrs are too scared to admit this lens has a defect. Definitely stay away from this Sigma Dusty lens.
hey man , was your copy above the serial 5564 ? wanting to pick 1 up saw that above the serial the issue was supposedly fixed
@@bensonaw3251 yes it’s below 5564 mine was 5552xxxxx but either way I recommend you stay away from this lens until V2 comes out or save up for the new Sony 24-70 GM. Here’s what UA-camrs are not telling you the new Sony AF with linear motors is faster at focusing. Even Tamron new Linear motors are faster than this, It’s not worth saving a few bucks to deal with so much hassle. Bdw my lens was serviced in New York Sigma.
oh dang, thanks for the reply ! will stick around to check out the new gm lens
Dziwne zjawisko jak na uszczelniany obiektyw. Czy przy kołysaniu na boki nie wyczuwa się, że w środku coś lata? W moim nie ma luzów w częściach zewnętrznych ale w środku tak. Gdyby to był obiektyw stabilizowany podejrzewałbym że to układ stabilizacji. Wykluczam układ ostrzenia bo raczej nie przesuwa się na boki. Nie jest wyeksploatowany i zastanawiam się czy to jest normalne.
Nigdy się nad tym niezastanawiałem. poszedłem sprawdzić i jak nim macham to coś w nim klekocze, nigdy mi nie spadł, wygląda na to ze tak już mają.
@@mateuszmikolajczyk3185 Dzięki, bo swojego też nigdy nie upuściłem a taka z niego grzechotka. Ważne aby działał
question is this a problem with all zoom lenses or just sigma i’m not a zoom lens shooter but looking to buy my first one this year
Sigma Art 24 70 isn't dust proof, it is an amazing lens but have the dust issue.
Its weather sealed, its just a manufacturer problem dust got stuck while making the lens
@@michalbajza47not it’s not lol. This is a lens defect. That’s just what sigma is telling people. Do you really think millions of lenses got dust in them during the manufacturing process? Pretty sure lens manufacturers have dust free environments just like cpu manufacturers. People need to stop believing sigmas bs. This is an issue and they don’t give a crap to resolve it properly. Issue is still present on newer lenses and lenses that have been sent in for the repair. People will literally defend a million dollar corporation just because they bought their product lol.
Wtf Sigma, Why dust problems in 2020?! It’s not possible.
I don’t understand why none of the large reviewers are even talking about this issue!
@@oklokih I have this lens right now, it is beautiful and I have no dust problem with it, I think the problem was when it came out, I had the tamron 28-75 and 17-28 I have it have sold for the sigma and have no regrets. the photos are much sharper, and regarding the change of focus for the autofocus is very very good. I advise it anyway
@@sed6717 How did they change the weather sealing from then until now when the lens was already released to the world? I just don't understand. Good to hear your loving it man!! I really want to buy one, but it is just that dust problem that's holding me back. I need reassurance it isn't going to happen.
@@sed6717 I just don’t understand how the weather sealing has changed from then to now?
@@oklokih supposedly sigma made an improvement once the issue was presented to them. I really want this lens also, but this makes me hesitate
Does the outside plastic ring you took out with the credit card pop back in just by pushing it back down or what?
this metal ring is stick by double side sticky tape. you need use "leverage method" for peel off this ring. You have to use a lot of force. try many times in diferent places. sorry for my poor English.
So do we need to replace the sticky tapes after we leverage that ring up? Or u can just push and hoping its not coming off
@@shafli4794 In my case, nothing wrong happen with sticky tape. I took the ring off, several times. I think this ring is only for decorative, for cover screws.
Awesome man. Thanks!
@@mateuszmikolajczyk3185 thank you man. just got my lens clean all by myself. if i send it to the service centre, it would cost me 80USD just to clean it
Good video sharing!!! Nice Sub done
Does anyone know if this issue has been sorted in later models? Also has anyone sent their lens back to where they purchased it from or to Sigma to have this done?
Supposedly yes. After a certain serial after 5504xxxx but lots of dealers seem to still have the older serials
No the dust issue still exist I would stay away from this lens. I bought my copy 12/01 serial 5557xxxx. Sigma did clean the dust under warranty but you have to pay for shipping every time I had dust issue. Also my lens came back scratched every time Sigma in New York cleaned it.
can I clean 24-105 art in the same way?
Does it have the dust issue too?
For what do you apply those white stripes?
for mark original position of parts before disassembly.
Mateusz Mikolajczyk does it have an influence how you put the front glass back on again? Also what screwdriver are you using for removing the screws i.e. what size? :)
@@khagesh7530 I have no idea, so just in case I've put back front glass in the same position. "ph00" screwdriver.
Mateusz Mikolajczyk Thanks! :) But honestly I think it's a shame that this lens seems prone to dust issues although Sigma clarifies it as dust proof...
Khagesh it is not dust proof is dust resistant which is two different things.
😢😢very fast dusty again....
ok it's pretty simple to clean but i won't buy this lens.
Missing out tbh
this lens is the one i would carry if i could bring just 1 lens
I will not be buying this lens, thank you
@@sonacphotos other people are saying it still wasn’t fixed with the latest serial number
Thank you!
