Yes, well the Pentax system works for normal everyday sort of dust that I

them "nice and dusty", hardly real world stuff.

Since there is no real dust problem in the real world that
could be fixed by a dust shaker, there is no need to
introduce them except for some nervous marketing dudes.

Yes, certainly dust is no concern at all. Which of course is why
companies can charge $100 for a brush to remove it. Loupes to see it
in $300 kits, etc.
Olympus dust removal works, which is what galls users of brands that
implemented useless systems. With those cameras, it IS a useless add-
on that is just another system in their cameras to break.
