But the first and very simple task would be to tell us how he judges the pictures as motion-blurred. By looking at them at 100%? If so, see my previous post.
gazonk, you're totally correct and I was about to make the same comment.

But then I saw ogl's last post and realized he is on a mission and not really having an actual problem. His using bold thread title letters should have warned me

Explain me, please, my problem - I have K200D and have a lot of blurred photos with SR OFF at "border" shutter speed - for example, it's 1/60 for FA43 or 1/200 for FA135. With SR ON - the situation is better. But my old *ist DS with worse mirror slap and lags of shutter was better. I had no any problems to shoot with FA43 at 1/60 and even at 1/50 without any SR. FA135 was better at 1/200 than now.

I think that it's a problem of SR technology.

I always avoid 1/60 for FA43, 1/125 for FA77 and 1/200 for FA135 with SR OFF.
I'm not sure how it could be a problem with SR technology if the problem you are having is when the SR if OFF.

The system must still keep that sensor in place

Of course, P. Smith with his admirable work did it for you already.

He found that there is a difference between #2 with MLU on/off of 0.8 - 1.1 Ám depending on orientation and SR on or off. I assume the flash method to reveal about the same difference between #3 and #2 MLU on. But I will await your test

So, what we know is that the sensor moves at most by about 1Ám due to mirror slap. This is much less than you would ever be able to notice, ogl.
but that was w/ K7 - may be sensor moves more than 1Ám w/ Kx ? at least the sound hints to a stronger air pressure wave

Somebody suggesting this for the K-x should repeat Peter Smith's test for the K-x and stay quiet if not.

If you don't wait for the SR system to arm, then it might fire. Make sure the hand icon is shown in the viewfinder prior to shooting.

SR could be having problems like this thread.

It will be interesting to see all the *ist DSLR (non-SR) cameras still functioning properly just as the SR cameras start experiencing problems down the road. More electronics/features = less reliability/dependability.

If Pentax can get enough of a groundswell of pentax users pissed off about the shortcomings of SR in the next two weeks, they think they might be able to move to in-lens VR without a bad word?

and loose the advantage of having all lenses stabilized?
not a chance.

SR has already been proven to work. it's not perfect, so is IS or VR.
so you work on getting it better and better, not dropping it and going to in lens IS
