The Nikon D600 is a 24.3 effective megapixel full-frame digital single-lens reflex camera from Nikon targeted for professionals to enthusiasts. The Nikon D600 was given a Gold Award by Digital Photography Review. It was announced on September 13, 2012 and began shipping on September 18, 2012.
According to Nikon the D600 uses the same Expeed 3 as used for the D4 and D800 series, with the same 12-channel sensor interface, featuring a very wide dynamic range which provides the possibility of lightening shadows or darkening overlit areas (high dynamic range imaging, HDR) with one shot when shooting in Raw image format.
