I see a very clear loss of detail in the first two comparisons at
Pentax K-1 II vs K-1 Noise Performance - Hands-On Tests | PentaxForums.com . In RAW, the difference is not huge, but it is there.
I JPEG, it is quite obvious. The K-1 II version looks blurred. Keep in mind this is a 100% crop.
For all the comparisons that follow, I like the picture of the K-1 II better, both in RAW and JPEG. This is especially true at ISO 12,800 and 25,600 . The text is clearer and more readable (or less unreadable!) in the K-1 II version, and yet has less noise.
One probably would not really use the ISO >51,200 and expect 100% crops to look great.
I just took a bunch of shots at ISO 100 to 819,200 . On my 4K screen, with no crop, there is not a perceptible difference all the way to ISO 51,200 On an HD screen, it would be even less. Even the ISO 102,400 picture is quite usable, if you never look at the 51,200 shot. ISO 204,800 and 409,600 are bad and worse. ISO 819,200 is completely unusable. Not really sure what the point of including those ISOs was.
