- We give you a look at the Nikon D4 in this episode, the camera that Nikon is calling its next flagship model. We got up close and personal with the Nikon D4 at CES 2012, and got to speak with Nikon's Steve Heiner about the 16.2 megapixel beast of a DSLR. The D4 is constructed out of magnesium alloy, and has a thermal shield under the paint to keep the camera safe in the most extreme conditions.
