D800, done it, anybody else??

That's interesting. I'm totally ignorant of matters involving signal processing, but it seems to me that an fft would allow one to measure spikes along certain spacial frequencies, so it is not surprising that such methods exist and that they involve a Fourier transform (by contrast, the Fourier transform of the Poisson distribution you get from photon noise is highly regular)

But as you say, DXO is pretty good as they are, especially when compared to other some reviewers out there (Bryan excluded, of course).
