Hmm, I guess I wouldn't call what I see in that crop moire or aliasing. The edges of the hairs outside of the specular highlights are quite smooth...you can BARELY see some jagged edges in a couple of them, but for the most part, they appear to be fairly crisp, clean, and smooth. I think the issue there is just the nature of the lighting and the nature of her hair. I've seen similar issues with the D800 (non-E version WITH the AA filter). I would be willing to bet that some softening of the light would reduce the harshness of those highlights, and eliminate what you are calling aliasing.
It is not "what I call aliasing", it is aliasing. The latter is not just moire of jagged lines. Extreme contrast between pixels is an artifact, always. Or maybe the model just needs to take a shower, I do not know. In any case, what I see looks awful.
EDIT: here is a computer generated aliased image, with no regular patterns. Bad hair or ... aliasing?
Well, if we are going to get technical, technically speaking every pixel in an image is an alias of the real image the sensor resolved. Artifact or not, to me, the girls hair just looks crisp and sharp, maybe a bit oily or loaded with some kind of hair product, with some harsh specular highlights.
Comparing the results of a layered sensor without an AA filter to a bayer sensor with an AA filter, I think there is a definite sharpness benefit
with the layered/no-AA approach, mostly offered by the fact that 100% of the image is being fully sampled at every photosite, vs. bayer which is sparsely sampled. If one finds it too sharp, there are a variety of ways that could be addressed....a mesh filter on the lens, post-process desharpening, etc.
Maybe this is just me, but I could never complain about too much sharpness. I am far more likely to complain about to little sharpness, as you really can't fabricate additional real detail in post.
