What makes the tiny digicams lenses so good?

Hmm. Since making good lenses is expensive, and since
(further) some corrections fight other corrections
(colour vs barrel distortion IIRC) has any manufacturer
(yet...) used Mega pixels and CPU power to
perform some of the corrections digitally
so that the lens could be better corrected
in the remaining ways (and/or cheaper to make) ?


It has been suggested but most lens makers AFAIK leave that sort of
processing to the RAW convertors such as DXO that wil correct for lens
distortion.

The trouble is it takes TIME so it is best done on the MAC not the Camera.

Ageeed - although faster CPUs may make the time "acceptable"

Here's a special circumstance where the manufacture
of "correct" lenses has already ceased, so post-capture
processing and calibration is "the only way"

Interesting stuff, IMHO.
