"Swamped?" Under what circumstances would that happen? I've
convered a half-dozen cameras (Nikon) to IR. When you eliminate the
IR filter in a Nikon, you also get rid of the AA filter which is part
of the glass stack. I've yet to see any moire in any images shot
with them. I'd have expected at least something to have shown up at
this point if the problem was that dire.

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.
