Sadly, we weren't allowed to share any images taken with the demo units (sorry, usual Nikon protocol), but what we can tell you is that both the camera's speed and quality weren't bad at all, and likewise with the 3.5-inch 854 x 480 OLED multitouch display -- the high pixel density makes the PenTile arrangement more forgivable.
