Live view autofocus is really fast! It is on par with my GH3, but as it is phase detect based, it does not have the jitter that comes with contrast detect systems as the camera racks the focus for confirmation. Only disadvantage against my GH3, as far as I can tell, is that it does not focus in the dark as well as the GH3. Otherwise it was fast and sure of itself. Now imagine a EOS M with this system. Canon really should have made that camera with this sensor.
As for how the images look, ISO 3200 from raw files seems fine, but without a proper comparison against other cameras, it is hard to tell if it is really better than its predecessors or its competition. We will see if we can get a unit to review, or at least test. No promises though!by
