I don't want to be the guy pushing his own gear and praising it to the heavens, but all Nikon 1 cameras offer 1/16000 (three zeros - not a typo) as shortest shutter speed. Folks who own the 32mm f/1.2 shoot it wide open in the sun. Of course, N1 cameras have some weaknesses which mFT do not.
With m43, you can use a smaller aperture to get similar DoF to the Nikon 1, so that partially negates the faster shutter speed of the Nikon 1 for comparative purposes.
That doesn't make 1/16000s unimpressive, though.
