Thinking about this shutter shock problem, more mass would dampen vibration and result in less blur. But there may be another factor in play which is sensor size. With a larger sensor, vibration is a smaller percentage of the image.

So it stands to reason that micro 4/3 sensors would exhibit more blur due to shutter shock, APS-C sensors less blur, and FF sensors the least amount of blur.

I don't think so, the new FF Sony A7R has big problems :

Correcto mundo.  Guess with a larger sensor the shutter has to travel a longer distance which results in more impact when the shutter bottoms out, resulting in a larger shock wave.  Compared to less impact on a smaller micro 4/3 sensor.

Funny how Sony knew enough to include an electronic first curtain shutter in the Alpha 7 which came "first" and made a purposeful decision to omit it in the Alpha 7R which came "second".  Sony works in mysterious ways.

Thanks,
