Yeah, but I think a great deal of that dust is pumped in through the focus and zoom actions. It gets in around the collars of the lens. If it's not a dust sealed lens, then it's fairly easy for dust to get all the way down through the lens to the imager. It just takes time. I imagine some stuff could get by the mount but I think mount seals are mainly for water. Who knows... I could even be wrong.
