Not all AA filters are the same. It's a balancing act by the camera manufacturer. The filter can be quite strong, but that knocks down overall sharpness of the camera. Or the filter can be relatively weak which makes a sharper camera, but increases the risk of moire.
Nikon likely is using a fairly weak filter in the D7000 as the sharpness is incredible with good glass. They likely didn't expect the D7000 to be seeing a lot of studio/fashion use. And the person I was shooting was wearing a HORRIBLE fabric as far as moire pattern is concerned.
And no, under the right circumstances, moire can be seen anywhere. Even with the naked eye which has a resolution several orders of magnitude beyond these cameras and lenses.
