Or....put the cameras in the hands of a reviewer that has read the manual and who has used Nikon before. In past reviews, DPR has assigned reviewers who knocked the Nikon because it did things wrogn since it was not identical to have Canon did it, calling any different between the Nikon and Canon as being a defective design on the park of Nikon. Their reviews since Amazon bought them have been biased towards the biggest sellers on Amazon.
Regarding the ISO of the D6, it is clear to observers that the specs are written by the marketing department by Canon and the testing/engineering department at Nikon. Each competing model in recent years have pushed the ISO rating to absurd values with little regard to the actual signal to noise ratio. According to Canon the 1D4 was the match to the D3s because they spec'd it as having 102k ISO but anyone using both cameras knew better. ISO rating is a proprietary licensed test routine and has specific conditions of test and measurements for a value so there is supposed to be a high degree of correlation between models and actual signal above noise. But Canon, at 102k have all been much poorer than any other make at 102k. To get the 5DIII to spec well, they resorted to heavy handed non-defeatable noise reduction that renders high ISO relatively quiet but also devoid of detail, with horrid artifacts and smearing. I would be very surprised if the 6D could do better at 25k than the D600, it would be the first time they did not fudge the specs. Stan St Petersburg Russia
