Any update from other users? Some people say they have these dust issues, some people say they don't. Some people say Sigma changed the design recently because of this but there was never any official communication about this. So it's hard to know what to thing of all this.

I bought the lens in May. In July I took a road trip from Maine to Idaho, and in September I took a road trip from Maine to Colorado. Lots of exploring dusty back roads, and hiking trails. I had never heard of the dust issue until someone on Facebook mentioned it. Pulled my lens out just now to make sure I wasn't somehow oblivious to it. My lens is perfectly clean inside, not a speck of dust.

I bet all the dust issues were a bad batch or two, or a problem that was quietly fixed.   Probably a non issue with new stock relatively soon
