Default As suspected, D4 not as clean as D3S

Did you measure how well your lenses performed at those wavelengths?
Perhaps the point spread function is sufficiently greater that less AA
filtering is needed?

Don't forget that the effects of aliasing may not show up as obviously
on natural scene objects as they would on objects with a fine, regular
pattern.

I shot city stuff too, no evidence of moire, and I used a variety of
lenses. I'll try to shoot some fine, repeating detail at varying
distances and see what happens.


So you didn't actually measure whether an AA filter was needed or not,
once the camera was near-IR sensitive. When you shoot your tests, be sure
to include the results with a non-converted camera as well.
