For David Millier

It could, Tom, but violets would be filtered about 40% "less" than reds with a diffraction-limited approach, would they not? (400nm versus 700nm diffraction) Whether that is good or bad, I have no idea!

On the other hand, I haven't too much trouble with aliasing when I bolt on my high-quality non-EX non-macro DC kit lenses, so maybe you have a point . . .

"properly anti-aliased", Dave? "Somewhat reduced"? "Around Nyquist"? Are you getting vague on us, by any chance?

My SD10 with no sharpening

A little lacking in contrast "below Nyquist" MTF50 should be at least up near 800 lph, IMHO. The good news is an MTF of about 9% at Nyquist meaning that artifacts would be barely visible, would they not? In this case the softness of the capture provided some quite good filtering, eh?
