Welcome to another round of comparison on this website. A while ago, I compared 21 Nikon D-SLR bodies out of my personal interest. How much resolution is necessary with the usual output devices and print sizes. Of course the level of post processing impacts results. As those requirements vary widely, I decided to upload all NEF files from the cameras, so that every interested reader can download the files from cameras he is interested in and apply his very personal post processing and scaling to the size he needs/wants. And THEN assess if he really needs the next resolution level.
I’ve tried very carefully to use the 21 bodies in similar ways in a stable setup to make the comparision as valid as possible. Covered bodies: D1, D1H, D1X, D2H, D2X, D3, D3S, D3X, D40X, D50, D60, D80, D90, D200, D300, D300S, D700, D3000, D3100, D5000, D7000 and as a special guest – P7000.
