On my Optio Z10 P&S there are several functions that are / can be made
after the fact, but must be made "in camera". These are "sharpening"
"shake reduction" and a handful of "filters" and "corrections".
I would guess that CA reduction and perspective correction could /
would be done post capture, but prior to offloading the card. After
all, all the information about the taking lens is there in the
metadata. It's just a software routine with sub-routines for each lens
model that it can cover.
It would be nice if over time Pentax did run through the older lenses
CA / Distortion to update the firmware for A*, F*, FA*, then A, F, and
FA. And so forth. And a way to tell the camera a bit more than the
focal length. If not in camera, then perhaps the Pentax software in
computer could create a file from the corrections you would make to an
images or three from one of these older lenses to correct for CA &
Distortion, which could then be loaded into the sub-routine cue of the
camera's firmware.

but if this is true I guess it's not all that useful.
