I had dust in my 55 zeiss and I think I asked the same question Haha. Bought it grey so thought it was refurbished or fake.
Actually I think it was metal dust. Only visible with torch. My non zeiss sony did not have this problem new.
I found one other thread on some random forum about it and after posting someone said the same thing.
I think the 55 has poor cleanliness control.
So I think they will all have this problem. didn't bother returning. I think qc is less than a real zeiss. Touits have a card with checkboxes and clean elements is a criteria
