"Dynamic Pixel Shift" in the K-1 II - what is it? (explaning by reference)

Yes, you'd have to make sure that the light coming from the flashes is essentially indistinguishable from another.

I am trying to remember the desired use case for previous need of flash with PS. If memory serves me correctly, one case had to do with reproduction of framed art and another being studio product photography. The necessary use of dPS off-tripod may be a disappointment to some of those hopeful users.

Addendum: Another case I remember was for slide/negative digitization with a dSLR.

Thanks for testing this out!

A few questions/comments

Flash model would be very helpful, even if a speedlight.
Full flash intensity?
By x-sync, is it safe to assume that X-mode is meant? (All sync on Pentax dSLRs is x-sync.)
Was sync not provided in other than M-mode?

Just being a little picky in an attempt to ward off a flurry of "I can't get flash to work with my K-1II" problem threads.

haha my terminology is flawed.

I shot with a manual Yungnou (canon version). It was at either 1/32 +0.7 ish and 1/16 I believe. I shot with ISO 100 and F2.8 so I was only concerned about properly exposing the image, so I could check out for any gain in detail etc.

X mode on the camera didn't allow for pixelshift to be chosen. I had to keep the camera in Manual, which is my preferred mode of shooting anyway. I would assume that it's only x mode that has blocked the features given how Av etc are just semi manual modes anyway. They shouldn't affect the nature of the camera like x mode does.

Thank you! This all helps. At those intensities the flash duration with a manual speedlite would be quite short with very short recharge times. I would expect that at full strength there might only be two flashes per dPS burst rather than the expected four.
