No AA filter = lots of sampling errors, some visible, some less.
In theory, yes, but you /did/ see the post from someone who had taken
several thousand photos on a filter-free D800, and only seen aliasing in
a couple of them? With "consumer" rather than "quality professional"
lenses the visibility of such errors is much less likely (as lower
lenses have lower MTF at the higher spatial frequencies).
I didn't see that post. But even if the moire is not visible in every
shot, it should be clear that errors are present in a large number of
images, even if they are not visible (fake detail etc.).
On the other hand, with 24MP on a APS-C sensor the lens alone will
probably cut off a lot of beyond Nyquist detail.
