Alamo and Ageless, I don't believe Gerard is tolling. He's from Canada and 71 years old. Not the typical profile of a troller.
Gerard, I see that you also have a nice 90mm Macro lens. It's very sharp. Could you please try that lens out on your K1? If the macro noise is acceptable, then you've just proven that the noise problem is more with your lens than with your K1.
I also own a K1, and the only time I've seen unacceptable noise is when I greatly underexpose the image and then try to bring it back in post. But just about any other camera would also produce unacceptable noise under those same circumstances.
Also, the K1's 36MPs produces giant images that when viewed at 100% on a large monitor are much larger in size than are the images produced from your APS-C 16MP cameras. That alone will give the "appearance" of increased noise. Down sample the K1 image to the same size as your APS-C images and you will then be able to do a more fair comparison - you should see clearly less noise and greater sharpness in the K1 image.
Properly exposed, the image quality (IQ) of my K1 is terrific!
