K20D vs. K7 in High-ISO RAW Noise

Thanks for the clarification; obviously I was confused about the problem.

I'll be sure to take some test shots around 1/80 - 1/100 to ensure I find them acceptable for my purposes. In the unlikely event that I can't live with them, and don't want to worry about avoiding that shutter speed range, I'll sell the K7 for much more than I paid, and get a K20D.

a really stable grip, which would surely be better than the shaky tripod which was used to establish the existence of this shutter induced blur.

I've been practicing a firm, steady grip for 30 years. I think I just might be able to do better than that shaky tripod.

Greg, congratulations on your decision and I think you will enjoy it.

I don't know whether I'll have the anti-shake blur

I don't know that a normal K-7 has any sort of Anti Shake (AS) problem as early samples of the K-x had that would make the K-7 any worse than any In-Body Image Stabilization (IBIS) system; however, it appears that it does have a slight shutter induced blur problem for shutter speeds between about 1/50 and 1/150 with a maximum blur for exposures of about 1/80 to 1/100 second, but as I said it is slight at only a pixel or two width. There are ways to work around that as in a really stable tripod or likely even a really stable grip, which would surely be better than the shaky tripod which was used to establish the existence of this shutter induced blur.

It was one of those type of problems which was and likely still is disputed as to whether it exists or not, as shooting environment and conditions may affect it even if it does exist.
