There are still some differences in sensor technologies.
It appears that there is still some
room for improvement for the Samsung sensor (based on a pre-production model) used in the K20D/K-7, with respect to dark noise.
Originally posted by nostatic If there is a trade-off between noise and detail, I'll take detail and make noise a choice that I make in pp.
Yes, any camera not doing that is patronising the user (not good).

Great contribution, Haakan!
I set my browser window size such that a "page up" and "page down" button press would exactly replace one version of an image with another.
I personally think the (chroma) noise handling (looking at ISO 1600 and 3200) is done best in this order: K20D (best), D90, 50D (worst). I did not expect this.
