Sony Nex 7 is killing all of Sony lenses (today, at least) by strong diffractions, but only Zeiss 24/1.8 is up to its sensor. Images taken with the rest of Sony lenses are soft and contrast loss to corners, center of the image is OK. So the D800E is at its best to apertures 5.6, mostly, and up to ones expectations with the best lenses ever possible, in some cases F6.7 is acceptable, but f5.6 is really border line. For D800 it is f8.0, and F 11.0 stops you. Please post something what IS your real experience, do not repeat someone else. So why do you think the D800E's sensor must behave differently than Sony Nex 7's one, against laws of nature, and my REAL experience, BTW? Diffraction is determined by sensor/lens resolution + effective F-stop, so, as better lens is as better is final image, if effective F-stop is inside sensor parameters. Just go over its parameters and you finish with image without detailing and contrast loss, especially to corners. Resume - one MUST use the best lenses on the D800E, to get the images up to one's expectations. The D800 is more forgiving, due to the law's of nature, again. Dimitri
