I think this may be a E-M1 specific question (but it may possibly apply to other Olympus Cameras that have 5-axis image stabilization like the Pen E-P5 & OM-D E-M5), but do any owners of an E-M1 (or camera with similar in body image stabilization) notice the sensor making noise like it moves or is somewhat loose or moving somewhat freely inside the camera body when not powered on? This goes away once I power on the camera. My guess is that the sensor actually moves to provide the i.b.i.s. so it holds the sensor more firmly when powered on. But, once powered off, there is no power keeping the sensor from moving so it can jostle around inside the camera when not on. Can anyone confirm this? Just want to be sure nothing was actually broken or not functioning properly in my E-M1. I had an E-M5, but I never noticed this state of the sensor and the noise it can subtly make when not powered on. Thanks.
