I was actually surprised by this humming noise, because I read tens of reviews before purchasing the camera with no report of that noise

It's AWESOME!... except that the IBIS creates a humming noise when the shutter button is half pressed-to focus-while taking stills (not really an issue for stills)

Overall i would advice you to get the body alone and find a good lens , if you can go for the Mkiii since its got less noise at the final image thanks to the newer processor but yet again noise can be reduced drastically withing the settings and by taking low shutter speed pictures

I hope there is a way to get rid of this humming noise while recording videos without disabling IBIS

I typically convert the EM10II Raw files with the DNG converter and process in Photoshop CS6 but at this high ISO I prefer to start with the superior noise reduction and distortion compensation of DxO OpticsPro

Unfortunately, after some research on the forums, I discovered that this humming noise is present on the E-M5 and E-M1 too

When I shoot a movie while handholding the camera with the IBIS ON, this humming noise gets recorded and is really loud and noticeable (really an issue for videos)

I have called Olympus to let them know about the humming noise, but they seemed to already be aware of it.
