Ok, here is the test:
k10d and Pentax 18-250 at 18mm, 50mm, 100mm, 250mm
k20d and Pentax 18-250 at 18mm, 50mm, 100mm, 250mm
k20d and DA* 50-135 50mm, 100mm
Not entirely scientific. Handheld (with 1/500 shutter speed and SR on however). k20d images are 20% "bigger" in dimension at 100% due to increased resolution.

k10d and k20d DA 18-250 and DA* 50-135 - a set on Flickr
I am showing the crops since that is the only place I think you will see major differences. All were cropped from highest res images viewed at 100%. I think those with a k10d and/or an 18-250 lens will be pleasantly surprised.
Thanks for going to all the work posting these excellent comparisons. Based on your crops, my bleary old eyes don't see much of a IQ difference between the K10 and K20D with the DA 18-250.
Unless I missed it, there's no comparison between the K10D and K20D using the high end DA* lens. Did you make that comparison? If so, please post the crops - that would be invaluable to those of us with K10D's who are still fence sitting vis a vis buying a K20D. If the lens quality of the DA 18-250 is the limiting factor (and unable to exploit the sensor quality of the K20D), we should see a clear difference in the IQ of the two bodies with the DA* lens, since that should make the sensor the limiting factor.
Thanks again,
Jer
