As a K1 Mark ii owner and party to the after-effects of what on the Pentax forum is considered a faulty DPreview, I notice that someone basing a decision on that review caused you to take the K1ii "off the table". "Aggressive noise" reduction was mentioned. Since all the camera makers have some noise reduction in their sensors, "aggressive" becomes a matter for debate ...

Not all cameras have Noise Reduction (NR) applied at any ISO setting.
For those that do the effect is generally at high ISO settings and not too extreme.

I am the person who used the term aggressive and I stand by that statement.
Here's an annotated graphic to give you some idea of why:

I suspect this signal processing is a combination of noise reduction and sharpening.
Personally I would not want this in my raw files.

The thing is, a chart doesn't provide evidence that there will be a negative result. No one involved in the storm and stress aftermath of the DPreview review claimed there was a negative effect. They argued that they would rather introduce the NR themselves. But time has passed. Others have reviewed the K1ii and placed it very high in their ratings. No one has complained of soft images because of noise reduction. ...

Well, of course they aren't "soft" if the signal processing is both noise reduction and sharpening. But I would never want my raw files manipulated in that way and I'm pretty sure I'm not alone in that. Clearly it can be turned on/off; too bad they didn't simply expose that to the user.
