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.

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!

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 KZitem. 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?

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...
