Nikon has announced their new D4 digital SLR. It's a 16-megapixel full-frame camera with an improved 51-point auto focus system, max burst rate of 11 FPS and a maximum sensitivity of ISO 204,800 (Hi 4). It's also got some new video enhancements, including full-time AF in video mode. It looks like a pretty straightforward reply to the Canon EOS-1D X. For the most part, the Canon's specs look better. But spec sheet performance and real-world performance are not the same thing. They both have the same maximum ISO but the Nikon's slightly lower-resolution sensor and larger pixels may give it the edge in low light performance. On the other hand, we're moving into realms of performance so crazy now, that to some extent, who cares?
