Another thought. Are you using mainly long throw zoom lenses? They suck in air as the barrel extends. With the air comes anything in it. Apparently Sony bodies are especially leaky - something I did not know, as I have never owned one. My Fujis seem to be quite tight, and no dirt problems so long as care is taken changing lenses
No all of my zooms move lens internally and the length doesn't change. I generally don't use zooms and utilize fixed prime lens
