Are you familiar with the above package?

Thanks, looks like it's all there, if I had a "viewer" that I could
select the specific items I would like displayed (not necessarily
printed, though) in a page format of multiple images, each on a line
for itself. My need stems from trying to learn quickly and easily
what exact conditions I used for each shot taken in a particular
session. It's just my way of evaluating what shooting setups work
best for a given set of circumstances. The thing I like about EXIF
View is - I can flip back and forth between the page with the summary
of the conditions to a page with the thumbnails, and can click on any
thumbnail to view it. From what you say, there is plenty of data
there, and evidently it can be viewed if the viewer can accommodate
it. So, it's not like Pentax withholds it from the user, is it?

Is Exif Tool available for downloading? Or have I failed to find it
in the stuff that came with the camera? That wouldn't surprise me,
I'm still learning this camera's features as well. And can it extract
at least some of the info from shooting only .JPG files, which is what
I use most of the time?

That response was very informative and helpful, thanks.

Thanks Mark. You and Paul, to whom I just replied, have given me
enough info that maybe I can get what I need. In all honesty, I've
not tried the software that came with the camera, so guess I'm to
blame there.

I note above you got all this from the RAW file. As I asked Paul in
the other reply, can I get it from the data available if I only shoot
in .JPG?

ExifTool is completely free, and can work just fine with JPEG files.

Yes, it works the same way with JPEGs. Of course, with JPEG files
you'll only get standard EXIF data (date, shutter speed, aperture,
focal length, ISO, Camera make/model, etc.) not any of the
non-standard things like lens model.

That's not true. In Pentax' case, and pretty much all the others' as
well, you get all that information in EXIF and MakerNotes. It's just
that not all software can read it to show it to you. Also, shooting RAW,
importing into a converter, and saving as JPEG presents a lot of steps
where such information could be lost by the software doing the work. For
instance, Photoshop CS and ACR drop the lens model.

Here's a JPEG straight out of the camera, with lens model included:
