It looks pretty noisy, but, you get that kind of result when you highly manipulate an image.  It does look like the noise you'd get at 6400 ISO or higher on a K-5II when recovering shadows.  The K-3 is supposed to be a little worse due to the packing of more pixels into the same real estate, but really not that much.

I am looking at a K-3 image over at dpreview. Here's the image:

Go down to my comment on it. If you enlarge the image (click on it after 
opening it) the sky and clouds strike me as very noisy for ISO 100. Some of 
that is oversharpening, but even the unsharpened image seems noisy to me.

This level of noise surprises me for ISO 100. Is this characteristic of the K-3 
sensor?

I stayed away from the K-3 because I was concerned about high ISO noise. But 
ISO 100??

Thanks,

Joe
