From reading Nikon's literature it seems to me that they are more concerned about "color aliasing" or the Christmas tree light effect.
I have had moire on every digital camera I have used, depending on the subject. My original 1Ds was terrible on clothing, where as
the 1Ds MKII seemed much better. I assume that Canon adjusted the filter. I read in the press release where in Nikon's Capture
software there will be a software filter or something to help counter the effect of color aliasing.
My P45+ occasionally shows moire on roof patterns, but it never seems to be that harsh, where as color aliasing can be very harsh at
times depending on the light. With addition of tech camera glass color aliasing is even worse now, but the extra detail to me is worth
the trade off.
Nikon to me has really taken a serious lead in technology. Where Canon took off with the 1ds in 2003, Nikon has caught up in spades.
Coming up with e model was a brilliant decision, something that Canon should have done with the 1ds MKIII two years ago. (At least IMO)
Over 3 years ago, MaxMax was showing the benefits of no AA filter on the original 5D.
