I have had Pz versions in the past and although they do work with SDM lenses they are quite inconsistent with focus lock.
Any idea why that should be?

If the haunting reference intrigues you there's a Youtube video about it (very poor quality)

The Pentax Digital Camera Utility has an option to extract the jpeg from the raw file.

PS Was Steve being serious in having a rant or was it tongue in cheek? I didn't see anything for him to get upset about. Puzzled!

Recent Pentax's can certainly be faster focussing than a 40D, that's quite an old camera now.
Anyhow, pleased you made the time to go and see and were surprised the experience wasn't so bad as feared!

Really its only use is the in-camera preview, or as a reference file if thumbnail library software cannot render the raw.

Try this little experiment. Take a couple shots using raw only. One with the jpeg setting at the smallest, the other at the largest. Then enlarge the previews in camera to 100% and see the jaggies on the smaller image whereas the larger one is fine. I used to think the same but am now pretty sure Steve is correct.
Confirm the differences by saving out the embedded jpegs.
It can still be worth saving both raw+jpeg as some software cannot render the raw files so without processing you wouldn't know what the image was. It also gives a duplicate in case the image gets malformed in the camera. (Can happen if you switch the camera off while images are still in the buffer, so I've found.)
To be doubly sure I take raw+jpeg in both slots now. Just because you have four images doesn't mean you have to keep them all, but helps to ensure you have at least one in case a card goes bad.

I'll continue to 'slum it' with an old version of Elements !

Is this the answer to low light photography.
Interesting article in today's Times about the first perfect digital camera, capable of recording each individual particle in low light, being developed by American researchers. Professor Fossum, who invented the technology that powers the process in smartphones,
and who has just been awarded the 2017 Queen Elizabeth prize for engineering, is working on a CMOS chip with a billion pixels that can each detect single photons at room temperature. It is expected to be available to scientists in five years and to the public in 10 years - or is this wishful thinking!!!!!!
Probably the K3ii replacement scheduled for an April 1st release date.
