AA filters on monochrome

2005-07-14 by claudej1@aol.com

Interestingly enough, between the slight sub-micron alignment tolerances,  
the non-apochromatic rendering of zoom lenses, and the fact that zoom lenses  
very seldom hit the sympathetic frequencies of a 6 micron well site pitch is  
what made the prism Foeveon moire free 99.9% of the time in the real world (6  
microns deman about 83 LPMM performance from a lens)
 
I see your point about luminance moire, which cannot be removed after the  
fact unless you have some pretty fancy pattern recognition software. So I  
suppose a AA filter micht be the ticket, but it would be MUCH milder (less  
sharpness destructive) on a mono sensor than a color one. Correct?

format), or rather poor lenses.
