This one is 25,600 ISO.
While it's easy to pick apart this image, for all purposes, this is incredible for being done at 25600. On the 5d2 this would have been almost unusable except for small internet files... If you're in a crunch and dont mind NR, this is pretty darn good. (Also keep in mind this is the most the D800 could go)... that's saying something.
If you consider D3s is still the king of high ISO that is available to buy (D4 and 1D X ain't yet), the following samples at ISO 12800 have more or less similar level of noise compared to this one at ISO 25600 by 5D III, provided that 5D III has almost 10 more MP than D3s.
