Can someone please post High ISO K20D photos?

So far, the photos I've seen have looked great but the ISOs have been 100 or 200. I think many of us would be interested in seeing some IS0 800, 1600, and 3200 images so we can better determine just how capable this new sensor is.

There may be some here: Not sure.
Image 31 (children playing in alley?) is at iso 800 per EXIF

BTW: I cranked and yanked and blew up the image (actually this crop is at 100%) to look at the worst of it (Don't try this at home )
NOTE: Pre production camera......

The popphoto article "first look at the k20d" has images showing the same shot taken at iso 100, 800 ,1600 and 3200... they look good.

Thanks for asking this question. Increasing resolution must - sensor size being equal - increase noise. So, are all things equal in a K20D? Or has Samsung found a way to mitigate noise in a small sensor with a process that doesn't dull the image?

I think my K10D is a wonderful camera, but at ISO 1600, it's dirty compared with my "old" DS2 - at least to my eye. If the new camera can do high ISO with significantly less dirt and still maintain clarity - well, sign me up.

We'll see.

Supposedly, Samsung/Pentax has packed more photo sites in by packing them in better, not by decreasing the size of each photo site. It's this decrease in size that leads to more noise as you get higher MPs. Apparently, the decreased the amount of circuitry around each site too. I think that some have been saying that each photosite is the same size compared to the 12MP one in the Nikon D300 and the Sony A700. Hell, maybe the photosites are even the same size as the ones in the K10D.
