Fenwoodian: I do not have K-1 anymore :-(
I just tried to compare with K-1 II classical Pixel Shift from tripod (motion correction ON/OFF), handheld Pixel Shift Resolution, handheld ES (electronic shutter) and handheld normal shot.
full scene - K-1 II + FA43
normal shot - electronic shutter - Pixel Shift from tripod motion correction ON
Pixel Shift from tripod motion correction ON - handheld Pixel Shift Resolution
Pixel Shift from tripod motion correction ON - Pixel Shift from tripod motion correction OFF - handheld Pixel Shift Resolution
for me, the best is classical PS from tripod, but handheld PS is also OK. so no big surprise. but what surprised me was the AF with K-1 II (this I absolutely did not shoot so well with K-1) look at the photos, in different light (sunny, cloudy, in shadow, fluorescent light, at night):
AF-S, spot AF (a small photographed subject and far from me)
FA77/1,9 Limited
FA135/2,8
HD DFA 28-105/3,5-5,6 WR
AF-S, spot AF with composition change, FA77/1,8 Limited @f2,2
AF-C, SEL-2
FA77/1,9 Limited @f2,2
the weak is only 4.4fps and a small buffer
AF-S, spot AF, FA43/1,9 Limited @f2,2
lights off in the office, ISO 3.200
photo taken through a double glass in the window with reflections from inside, ISO 2.500
AF-S, spot AF, FA31/1,8 Limited ISO 16.000 (@f10 due to the ISO test)
I hope that K-1 will also get firmware with AF algorithms from K-1 II :-)
...so where are the bad results from Dpreview?
PS: I'm sorry for my English
