here are some images taken right from the card, no post work, no cropping. Yes, converted to jpg for posting.
Please Note: all images were captured on a pre-production model.
Did not have much time to learn and customize the camera, so these are pretty raw. This first one has the top people of Nikon and one of the ambassadors.

I did do some video shooting with a music video ambassador as the guide, but will need to shoot my own for a true look.
His workflow settings were damn good, and you need to make sure you have the once you are comfortable with.
