There is nothing malfunctionning here, you just need a faster shutter speed.
And i would suggest you to disable SR in daylight and keep the shutter @ 1/ focal lenght * 1.5 sec to make sure shots are crisps.
The barn photo was taken at 1/200, with a focal length of 28mm. The car photo was 1/400 and 48mm. Even without SR, those are more than adequate shutter speeds.
The calendar shot was at 1/10 second, and at full zoom, so I agree that it was pushing the limits of SR. However, I took a number of other photos of the calendar using the same settings, and the SR compensated reasonably well. The problem has also occurred other times, seemingly at random. I haven't detected a pattern.
Also, this behavior is new. I used the camera for a year up until last November, and I do not recall similar results. Since then, as I mentioned in an earlier post, the camera has been to C.R.I.S. three times for separate repairs. If it has to go back to them again, and that's the way I am leaning, I am going to ask Pentax to replace it.
