Great light is a big word.
This one is at ISO800 with the K10D
I now use the K5 for this and use ISO1600 and get even less noise but the K10D images are surely useable.
And like i said I think the K10D might be better then the K5 at ISO100 so it has his strengths and i hardly use the K10D or K5 above ISO400 anyway.
Also the noise of the K10D is very different then that of the K20D, i find it less of a problem most of the time.
So yes you can see some noise at ISO400 but the noise looks good, natural almost at that level.
