For all the photographer pixel peepers out there, have at it with the Nikon D800 vs. Nikon D700 high ISO comparison. All I can say is “wow”. I’m not saying that the high (25600 ISO) is noise free, but it looks a bit like my 4 year old DSLR’s ISO 800.

Note that images under ISO 3200 aren’t included in the comparison as there is “no visible noise”. Amazing.
