I am a Nikon man. I have used Nikon for long time. I got this D600 in April 2013, unfortunately without knowing or bothering some review on sensor dust problem. I have posted some picture on this. It is bitter thing that Nikon after releasing a statement on this problem, if not mistaken by Feb 2013, continued selling this camera. I have not lost hope in Nikon. Apart from the dust problem the D600 is wonderful. If you do not go above f16, ever, then you will never regret this camera.
