Adam, do you know, is there a reason why the 6 has this and not the 7? The 7 has twice the megapixels (48) as the 6 does, so in my little universe, it seems as if it would be reversed.
My initial thought is that with the lower resolution, the likelihood of moire from repetitive textures is more likely, but I never had that issue with my D500 with no AA filter and that's only 20MP. Your guess is as good as mine. I'm hoping 24MP with AA filter is at least as sharp as 20MP with no filter; I guess we'll see when it arrives.
I know back in my pressman days while in college, we had some occasional issues with Morie patterns, but mostly caused by two screens of the same pattern and resolution. In color printing (lithography) there are distinct screens used for 4-color printing that do not do this in relation to the 3 other screens. I will do more research regarding this and see if my buddies at Nikon have any information regarding this that they can add to the conversation.
Be well and thanks for the response.
