Does turning off camera to change lens help sensor dust?

Some amazing photos on your flikr Alan! Just gorgeous thx for sharing! I only wish the new additions of PDAF to the NEX-6 didnt also allow you to Brick your new camera by simply making a  common unconscious decision such as Hot swapping a lens.

@volune I agree reading your manual is always important but Hot swapping lenses has been done by many experienced photogs for years with no problems even while using Sony bodys (NEX-5, NEX-5N, NEX-7 all the SLT's). Unfortunately the NEX-6 is not one of them.
