Hopefully somebody on the list with good knowledge will speak up. Most
of my experience with sampling systems was long ago. The filtering can
not be done after the signal is sampled and the filter is carefully
designed to optimize the performance. So for a camera the filter (some
sort of piece of glass) is going to blur closely spaced points together
with carefully chosen ratios between how much signal is smeared at each
distance away.

I don't have a clue how a lens is designed to do that. Tim Hughes'
comment about using IS lens technology is easier for me to visualize.
