My first thought...
"A 51-point AF system for improved subject acquisition and focus performance under dim lighting. In addition, 11 focus points (five at center with an addition three to each side) are fully functional when lenses with a maximum aperture of f/8 are used."

Take that, 1DX.

Also:
Continuous shooting at 4 (FX-format/5 : 4 image area) or 5 (DX-format/1.2x image area) fps*
*When powered by a Rechargeable Li-ion Battery EN-EL15
When the MB-D12 is mounted on the D800, high-speed continuous shooting at approximately 6 fps* using the DX-format image area is possible.

So given you need to add a battery grip to increase the fps like other nikons, and it does dx-cropping to get to 6fps, it's not much faster than a 5D2 for the most part.


  • CompactFlash and SD dual memory card slots
  • Support for SuperSpeed USB (USB 3.0)

Nice, but I just bought a nice usb3.0 card reader for $20, so don't care.
