Very true, of course. One step at a time, and a balanced effort - upgraded AF hardware and software in the body, matched with upgraded lens hardware/software.

Pentax autofocus is a subject that never seems to die. :)
We've gone through different phases of identifying Pentax camera deficiencies (not so great high ISO pre K-5, lack of a FF pre K-1 etc), but those issues were solved. It would be good one day soon for a Pentax body to arrive that can finally end any debate about the competitiveness of Pentax AF. And also end the video debate ...

Same here. The responsiveness of the AF operation.
But the idea, as the EXIFTOOL source code comment reveals,that it has something to do with how long (in ms) the AF sensor has been exposed to light in the lead up to an image being captured may be totally related to the responsiveness of the AF.
Time to post this K-3/K-1 AF infographic I did a while ago, just to remind us of what the hardware is:
:
Not in the diagram, however, is the additional SAFOX 'light source' sensor positioned next to the penta-prism of the K-1 and probably the K-3 too:
'to optimize autofocusing accuracy by compensating for focusing errors caused by specific artificial light sources' - probably tungsten light.
