Updated: We've just added a noise and noise-reduction page to our hands-on preview of the Nikon D600. We've got a production sample D600 in the office, and over the coming weeks we'll be adding test pages to the preview as we move towards the publication of a full review. Our final analysis of the D600's image quality will come later, but for now, click the link below to see for yourself how Nikon's newest DSLR measures up to its competitors in terms of noise in both JPEG and Raw mode.
