That of course is true. Shooting at f/40, on which the test picture was taken, isn't something I would normally do due to diffraction.

But it puzzles and perhaps worries me how that dust came in the lens in the first place. I would expect some dust in my 40 years old Canon FDn 50mm and 50 years old Meyer-optik Orestor (and there is) but in a half year old modern lens?

zooms can suck air in

I think it is minor as long as it doesn't impact pictures
