One of the highlights of this month's CP+ Camera and Photo Imaging Show 2012 in Yokohama was Nikon's new D800 digital SLR camera, aimed at multimedia photographers and videographers. The 36-megapixel monster is once again spurring the debate over how many megapixels is too many megapixels.

The D800 is the successor to Nikon's D700, which was released in July of 2008. That was a 12.1-megapixel camera, and the D800 is exactly three times that, with a 36.3-megapixel FX sensor, and is capable of shooting at 7360 x 4912 pixel resolution. It has a native ISO range of 100-6400, but is expandable to ISO 25,600.

The company's director of marketing, Bo Kajiwara, noted that the D800 is a response to the quality that consumers are demanding from cameras these days: "The Nikon D800 re-imagines what is possible from this level of D-SLR, to address the needs of an emerging and ever-changing market; this is the camera that is going to bridge the gap for the most demanding imaging professionals, and provide never before seen levels of SLR image and video quality."
