Any K20D owners willing to help?

I'm looking for a K20D owner willing to take 3 shots with the lens cap on @ 1/30th sec for ISO 800, 1600, and 3200 and send me the RAW files. I'm curious to check out the noise patterns. Please PM me if you will help. Thanks!

Which lens and aperture do you prefer?


(Sorry, couldn't resist )

On a more serious note, a single ISO800 raw file may be ok, as ISO1600 and ISO3200 look like ISO800 boosted by 1EV and 2EV, respectively (with a slight extra clipping in the black). In general, it is known that noise must not be judged from dark frame shots.

Nevertheless, I prepared and uploaded a darkframe shot at ISO800 for your convenience. Enjoy.

Thanks much.. I'm not looking to judge the noise in any real life sort of way, just want to look at the pattern.
