DxOMark reviewed the D600 sensor image quality and assigned it an overall score of 94, the third highest rated camera sensor in its camera sensor database, behind the D800 and its sibling, the Nikon D800E.
According to Digital Photography Review, its build quality and user interface are between the D7000 and the high-end full-frame D800. It includes almost all of the video capabilities of the D800, except that the D600 body cannot adjust aperture during video recording.
The Nikon D610
Most sites that sell the D600 have it listed as discontinued (as of Nov 2013). This is most likely due to the release of the D610 and the sensor oil/dust issue that have plagued users since the initial release of the D600.
The D610, announced on the 8th October 2013, is an updated version of the D600 featuring an improved shutter mechanism with a new quiet continuous shooting mode (3 fps), slightly higher frame rate of 6 fps and improved white balance.
