Unfortunately, from the clips that have been posted on Youtube so far, it appears that moire/aliasing rears its ugly head. It isn't nearly as noticeable as on the D800, but it isn't as clean as the Mk III either.
So, between this, the lack of aperture control for electronic lenses while recording, and the questionable stock bitrate...I'm losing hope that this will be the industry shaker that I had hoped it would be.
