Re: Modern Sensors Missing half the AA: in the Horizontal or the Vertical direction?

This may be also of interest.

I looked at differences between D600, D610, D800 and D800E.

Too bad DxO has tested only three lenses with D800E and all of them are third party zooms. I picked Tamron 70-200/2.8 from that as it is known as a sharp lens.

Tamron 70-200/2.8 with D600 (click on Measurements tab/Sharpness/P-Mpix)
Tamron 70-200/2.8 with D610 (click on Measurements tab/Sharpness/P-Mpix)
Tamron 70-200/2.8 with D800 (click on Measurements tab/Sharpness/P-Mpix)
Tamron 70-200/2.8 with D800E (click on Measurements tab/Sharpness/P-Mpix)

You can see that D600 has worst sharpness of the four, D610 and D800 are same, D800E has best sharpness.
Fact that D610 and D800 are same while other two are different suggest that this is related to AA filter.

Relative difference between D600 and D610 is smaller than relative difference between D800 and D800E. That could be explained by AA filter in single dimension only in D610 as suggested Optyczne and in this thread.
