So, Rice? Do you still claim, there will be no difference in resolution, cause pixel count is too low? :P

You're really funny. Learn whats Nyquist theory about before spamming my site further!

So, do we see more detail or just some Nyquist frequency artifacts? :P
As you can see with AA filter we are still a lot below the Nyquist limit.

The spatial frequency of the model's hair is not that high actually.

So What are we saying? I do not see the relations and seperations between the hair? As perceptually I do.
As for the Nyquist I am only used to seeing charts on sites showing the results, as again I do see a difference, and it looks good.

Although I stated otherwise before, I do see a significant improvement over the standard II version. Although this is pretty hard to judge from this...

hmm....would really like to see a FFT spectrum of a testframe with high frequency patterns comparrision of with and without AA filter versions. but then he testframe would have to go far beyond the resolution of the sensors resolution to show arefacts. but with the spectrum we could see how the filter is designed...

in this image it seems like we already in a range where die AA lowpass already gets effective, but no higher fequencies are in the picture that could cause aliasing effects. exactly the case the non AA fiter camera is designed for.
