Yes the first image was a typical window screen on the out side of a window and was only on the left side. (PP to match WB a little and exposure a bit. Done quickly for an example for this thread) Image was to show what moire' I typically see in any images that have it. They well have the rainbow effect and I do find on some that are bad enough, found a portrait pic last night that had it badly in the luminance channel, that it require photoshop to remove. However I haven't figured out the luminance channel yet as LR4.3 handles the rainbow effect just fine.
Unfortaintly I do not know anyone that has a D800(E) other then those on this site. I have one friend that shoots with a Canon 7D and another with a D300. So no real way to compare. I wonder if I or you had a chance to go to FotoForum, if they have anything around the store that I know would cause moire' and test each D800 with the same lens and on a tri-pod to see how much a difference could be seen in a real life personal test. I know DPreview had a section comparing the two, and seemed the E had more then the non-E, which still produced the effect of moire'.
