A reader pointed me to this article by Fotosidan – according to a Nikon rep, the new Nikon 1 J3 and S1 mirrorless cameras do not have an anti-aliasing (AA) filter, just like the D800E:
“A little unexpected technological innovation is that both the new cameras do not have anti-aliasing filter, which should provide some sharper detail. According Matte Haglund, Nikon has learned much of D800E and now feel ready to skip the AA filter in these models.”
The lack of AA filter will deliver sharper images with more details and better resolution and add moire patterns in certain situations.
