yes, very interesting about the Oly cam!, so for stills it maybe the better tool? But this low pass cancelation is unclear to me. does that the AA filter can retract back?
I don't know about 1% difference, I think the subject matter makes a large difference in the way a AA image looks vs a nonAA image. I shoot lots of product and it is not 1% in my eye, its a overall dimensional quality difference. But I have not tested the D800e vs 800, or the Foveon. Some time back I tested a PhaseOne 22mp, a Kodak SLRc, a 1Ds, 5Dmk2, 1Dsm2, The Kodak SLRc was closest to the 3D and sharpness of the Phase. I used LeicaR on the SLRs. I also tested with a 180L. Nothing scientific, but I did my best to keep the variables as equal as possible.
Now the pixel size with lens is something that maybe a big factor and its not an area I have exploited to include in my findings, and perhaps a major flaw...But the Kodak SLRc with Leica was noticeably a crisper image and nice sharp with bite. The 1Ds was soft, but the image was creamy and refined looking and 5D while having more resolution did not have the bite nor that refined look. Phase did have the bite the sharpness the refined and resolution. The Leica on the either DSLR was sharper than the 180Canon.
Sorry I know this is rather hard to pin down as having a worthy valuable assessment, but it was for me in choosing my tool for the job. The Kodak had major issues with light coming towards it. ISO 6 was interesting. But the 1Ds's became the portable cameras, and then the 5Dm2 replaced the 1Ds's as well. My take away from that was the NonAA cameras had the bite and dimensional quality, and I summed it up as the AA flattening the image and giving them a slight fuzziness. Again, sorry, I know there are 3-4 here just steaming as they likely know the exact scientific makeup of these and saying the color bleed, the moire, the xyz...but this was in studio controlled with same subject. I shot a ring item to fill frame. At the time I used a 3000macro on the Phase. Now I still use phase but with Shneider180 lens.
Perhaps the 40mp Oly may be a better fit for such needs?
