A side note, the dust vibration mechanism in Olympus dslr is flawless and has been for years. I never get dust on the sensor, and shoot constantly under harshest conditions even changing lenses on a windy beach frequently.
Not that Oly is perfect in every regard, to the contrary... but you other brand shooters should really get on your manufacturers about making something similar, that does not require a professional service or the risk of damaging a critical piece or camera's functionality. Squeaky wheel gets the grease.
