lens Sigma 24-70mm f/2.8 DG DN . How to remove, clean dust from inside.

[@rafi039]

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!

[@mrwashur1991]

Pretty sure they clean it for free. I would get it professionally cleaned then sell it lol

[@yoiain]

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!

[@spannertechXXI]

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.

[@jettlifeweddings]

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.

[@johnnyainsworth4892]

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.

[@davehanner360]

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!

[@TheLAexplorer]

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.

[@kite987]

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.

Don't set the dust ring down on the adhesive side like I did on a piece of paper!!! Great tutorial, thanks!

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 KZbin. 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?

[@MakingTracks]

Hello, is there any update in regards to removing those metal clips ? Thank you.

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.

[@chrismonsen]

I got mine less than a month ago and I have a noticeable dust inside... 😅

[@forkedMuffin]

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...

[@mexmax1657]

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...

[@drakedoggy103]

well who is the real tampon ? in my opinion the on that has bad qc and problems...

[@forkedMuffin]

@@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
