What you say would certainly help.
I heard an unsubstantiated rumour that they also managed to redesign the sensor mounting on the SR mechanism and heat conduction to the chassis to improve long-exposure heat dissipation. Another possible reason to go for the metal chassis? Who knows.

The fact that they have improved sensor cooling *and* have finally allowed turning off automatic dark frame subtraction on long exposures means that the K-7 can now enter the ranks of astrophotography. Seeing the wonderful high ISO performance also bumps its utility in this regard.

From these images, I would say I have more than one stop of improvement over my K200D, with higher resolution. It's what I was after.

Hi Yakiniku,

Thank you for posting the links!

I don't speak or write Japanese. Can you see what the K-7 settings were for the different tests, for example what was noise reduction settings? I'm unable to see exif with this computer. can you post the exif if they exist?

thanks!

Hi solar1,
The settings are: AV mode, NR OFF, 77 segment, AUTO WB, ±0EV, JPEG★★★.
First set with Carl Zeiss PlanarT*2/100, second with DA★55/1.4SDM, according to the author.

Well, not quite... From the manual that Ned B showed on his blog for a while it seems that if exposures longer than 30 seconds are used (in B mode) the camera will do the automatic dark frame subtraction anyway. You can only shut it off for exposures shorter than 30 seconds.
