This Chinese reviewer shot the K-1 in from ISO 6400 to ISO 204800, SD card is not allowed to be put in so he showed those images from back of the camera screen. Those pictures seem very encouraging in turns of ISO performance, however not sure what the image format those are and not sure noise reduction is turned on or not:
Interesting, thanks.

ISO 204800 looks ... bad. I don't think I'd ever use it. And I have a strong suspicion that in-camera NR was on, because I see a lot of luma noise but not much chroma blotchiness. (The image sure got enpurpled overall, though.)

But 51200 looks pretty good, honestly, for some uses.

Chroma noise reduction doesn't affect sharpness. It's just desaturation. It's just a time saver when applied automatically.

it seem to have face detection too
No news there. Face detection in LiveView has been a Pentax DSLR feature since 2009 and the K-7.

Face detection working with optical viewfinder AF would be big news with the K-1. (And something that, IMHO, is overdue in Pentax).

Of course.
But face detection (Face Detection AF) in LiveView first appeared in Pentax in the K-7.

6400 ISO looks great, 12800 looks quite useable as well. It will be interesting to see some of the final output, I'm not really sure that photographing the back of the camera screen tells you lot.

The rep confirmed that the SR is still active while the pixel shift is working. He said that it should be good for handheld shooting in a lot of situations as long as you keep to a relatively high shutter speed.
- I asked about the sensor and ISO performance. According to the rep, the K-1 is at ISO 12,800 like the K-5 IIs is at 3200. The base ISO is 100 and Ricoh does not offer ISO expansion. It is exactly the same part as in the D810, but Nikon uses the sensor outside the manufacturer’s recommended ISO range, while Ricoh won’t do that. The reason why the K-1 is about one stop cleaner (he had images to show this) than the D810 is Ricoh’s improved “engine”.
That's really interesting news. Thanks.

I will be really keen to see the DxO test results for the K-1. Particularly the S/N and DR charts and their curves. Comparisons with the D810 and A7R will be very interesting.

"Improved engine" sounds scary, are they messing with noise reduction on the raw files?
You get better results with RAW files if everything is off in camera, and adjust in PP. Especially noise.

Don't know, I never used the K-7 that much, owned the K-5II but never know it has it since I almost never use live view on it, but there you go, learn something new every day.

However it's live view performance is pretty good, seems to be on par as dual pixel Canon bodies and Sony SLTs.

I won't bother about ISO 204800, more interested about ISO 3200 to 25600 like.

The most I would usually go for most FF cameras is ISO 6400-8000, I would count how many times I actually went higher than that coz ISO 12800 on most FF cameras I have used before just isn't very good, if I need more birghtness, LR is my friend. However, if a camera's ISO 12800 performance is good then great I will gladly use it, anything above it will depend on how the camera performs. The point is, so far it seems like the claim that the K-1 will have a cleaner ISO than D810 might be true, but again let's how this turns out in the actual production model.

Good luck with that.

The camera settings only effect the JPEGs, so the RAW files are never compromised. I think he is referring to Pentax having a history of applying a little noise reduction to RAW files at high ISO. The K-5 applied NR to RAW files at 1600 and up, and they still looked better than the Nikon or Sony cameras that used the same sensors. Sony sensors have the A/D conversion built into the sensor and apply some NR to the files before they go to the image processor.

Does this mean that it got movie SR?
as stated in the Adam Q&A with Ricoh representative 2016 CP+
only electronic SR in movie mode
since they haven't found a solution to eliminate the noise of SR during video shooting

Some settings still are (potentially?) affecting Raw like Dark frame substraction (if it is even still used in current dslrs).
It was mandatory in the K7, very annoyingly and applied even if shooting Raw only.
It may be a single exception though but I think much more trickery is applied to raw than we would like to know, Ricoh or any other.

Indeed. If they do 645Z trickery....
