@fotorrhoe - Where is a reference confirming that Sony has dual IS?
I've never seen anything official about this.
As for the efficiency - given Sony's resources, I've a hard time believing that their IBIS is 1-2 f-stops less efficient for no reason.
As for IBIS in APS-C bodies - the efficiency is also a matter of the mass that has to be moved, I'd say. Probably the reason why the MFT bodies are the best in the business in this respect.
