Read the article and all the threads. It was about the cannon 6d which appeared to be under exposing by two f-stops. It was not until the next round of the investigation that it became apparent the D600 might be over exposing by 2 f-stops. The nikon was not initialy looked at and thus not a whole lot of "testing" was done on it. The camera was also using a third party lens. There is more information being gathered and a host of possiblities. The D600 has been out for awhile and I think if this was a common issue it would have been noted in this forum.
