Nikon has published a technical guide for getting the most out of the resolution that the D800 offers. It pretty much confirms that diffraction starts showing up after f/8 and you’ll have to use impeccable technique to get the most out of the camera’s resolution for pixel peeping and making massive prints. It also notes that you can utilize diffraction to alleviate moiré issues on the D800E. Before you tweak out about it, however, remember that you should only worry about issues that affect you and your photography. (via Rob Galbraith)
