I chose the plane footage to demonstrate the kinds of shots I would otherwise not be able to get. I could never whip out my XHA1/Letus Ultimate and point it out the window as the plane is taking off or just getting to its altitude. I held the camera to the window spreading both my hands on the glass and thumbs supporting the Mark II.
The second set of shots is from the dancing water at the Bellagio in Las Vegas. This was a pretty low light situation but, again, the camera did a great job at keeping noise at bay. You can see the exposure shift when the water stops at the end of the sequence. This highlights some of the limitations of the non-manual part of shooting video.
This footage ties into my review of the camera: http://exposureroom.com/library/reviews/view.aspx/25/
