You can also set the K1 to use an electronic shutter in live view mode,
no pixel shift.
With the camera set to 3 second delay and electronic shutter, you can
minimize any kind of shutter shake almost as effectively as using flash
and minimizing / eliminating ambient light. But I found that many
artificial light sources create some degree of banding due to the
rolling shutter effect of the electronic shutter. LED, Tungsten and
compact fluorescent bulbs all produce it. I finally found a brand of
LED's that does not produce noticeable banding by trial and error.
Aside from banding the problem with ambient light is that there can be a
surprising amount of movement in subjects due to minor air currents or
vibration.

In my enduring foray into extreme macro, I always come up at vibration
as the ultimate limiting factor to sharpness. Good camera fundament is
a must. Flash is a necessary evil. Mirror lockup is an indulgence for
vibrations in the sincerest catholic sense of the word.
But the shutter's guilliotine movement is hard to circumvent. Some
macro photographers like John Hallmén of Flickr fame
(https://www.flickr.com/photos/johnhallmen/), switched from a Canon
DSLR to a Sony mirrorless for studio work for that reason.
In the Pentax lineup, this issue makes the Q7 a very attractive
alternative, at least when megapixel cravings can be curbed.
However, one genious little thing about the Pixel Shift feature in the
K-3ii, K-1 and K-P, is that it does use an electronic shutter.
Combined with mirror lockup, the camera will flip up the mirror _and_
open the shutter on the first press of the shutter button, and then
start the exposure on the next.
Geeky, I admit, but I thought that was neat. :-)
Negates the use of flash, though. :-(
Carry on. :-)
