Originally posted by Ash Does it also occur with or without lens correction and highlight correction? I have so far had zero lag in my image recording and instant review with non-Pentax lenses.
After a Reset, both "Lat-Chromatic-Ab Adj" and "Diffraction Correction" are set to on, but disabling them make no noticable difference to the processing time. Likewise, "Highlight Correction" was set to Auto, but if disabling it makes a difference it falls within the margin of error.

Originally posted by biz-engineer At ISO12800, the lag is only after the shots, and it is around 1 sec. at ISO6400, 2 seconds at ISO12800 and about 3 seconds at ISOs higher than 12800, but it doesn't affect burst rate, there is no wait time to shoot additional frames.
This is about half the processing times that I have found. I.e. at ISO200 there is a one second delay, at 3200 this has increased to 2 s and at 12800 the 4 s originally reported.
The difference between mine and "biz-engineer"s figures could be explained by a difference in methodology.
In my case the test image [Windows 10 Stopwatch] was a 14" computer screen [1920x1080] with one line of large black text on a white background. This background is not a uniform white, but pixelated when enarged. How this affects the processing time is more than I can guess, todays noise supression algorithms are probably different from what we used 50 years ago.
For the test I disabled Lens Corrections, Highlight Correction and Instant Review. After a picture of the test screen I waited until the Status Screen reappeared and the took another picture. From the recorded times my reaction time [0,1 s] should be deducted. Any difference in processing time between raw or JPG images falls within the margin of error.
