It certainly does look like mashed shutter esp. considering it is not observed when camera is on tripod. I been told many time before by other people on the forum and Pentax repair crew that it is indeed a user error.
On the other hand my handholding technique is quite good, I been doing photography over 20 years now starting from all-manual range-finder so I should be able to tell. In addition I am not getting anything like that with my Canon and now I am not getting anything like that with another K-x camera.
If it is mashed shutter then mash is introduced by the camera which is understandable considering how strong mirror slaps and that CCD is not actually attached to anything.

Not sure what mashed shutter is but on 1/30 issue does not disappear, it just that second edge on the picture is not so visible.

I'd say don't bother if you did not notice issue yet. My second sample has some of it but I can totally live with that much blur.

SR OFF/ON no difference to me. Ordered another camera from Amazon to check - same issue there, sent it back.

Pentax USA would not. They replaced mirror assembly at first then started blaming user error. Calling headquarters did not help, complaining through BBB either. Return this camera for refund if you can otherwise I have no idea what to do. I am stuck with mine. Attempting to repair would be first logical step though, just don't expect much out of it.

They must have a way to write new serial number into lens firmware.

falconeye,
what prevents me from returning defective camera to Amazon instead of good one once I am done with my comparison?

Yes, it requires reasonable amount of effort to close it. Tested with different batteries including eneloops and alkalines - issue still there.
Some people who exchanged their cameras saying that cameras without the issue have much quieter shutter sound. Maybe it has something to do with dampening material around focusing screen? Density/positioning?

Dealer is Amazon.com, been 4 months since (all that sending to repairs) so they refuse to take it back. And Pentax does not acknowledge the problem.
New firmware did not help.

Issue seems to be reported on serial number ranges
346XXXX - 350XXXX
Although there are also one report on 343XXX body. Color does not seem to matter.

'only' is just speculation. At least confirmed cases of mirror shake seems to be coming from white bodies.

Guess I am getting too defensive after all these problems. My apologies. Let see if anyone who has pentax connection in US appears.

It seems like only white bodies affected, I started thread on another forum to collect more info about serial numbers and body colors.
Also the issue is very consistent with my K-x at least and easily reproducible:
contrast subject (text), 1/60 - 1/125 sec exposure, handheld. That is all I asked Pentax to test. In response they sent me back picture shot on tripod and copies of pages from manual where it says - one should always use tripod for macro photography - 1 meter (3 feet) distance they consider macro.
Then there is no issues shooting 1/30 sec. If I had such bad handholding technique, would not it be worse? I am proud to say that I was able to take perfectly sharp pictures with Canon, no SR, IS or any other kind of stabilizer at 1/10 sec, 28 mm lens.
What you see on my test are sequential shots takes one after another. It is 100% reproducible, visit my house and try yourself if you want to.
I guess I have to make youtube video about this issue.

It has been 4 months since I am trying to resolve one way or another issue with my white K-x kit. It is that dreaded mirror shake issue on 1/60-1/125 sec.
It was sent to CRIS Camera (USA official repair facility) for repair where mirror box was replaced which did not help. This is test I did after it came back (has now close to 10 thousands hits):

(pls. don't embed it, it uses all my traffic)
Second time at CRIS they would not acknowledge problem and send it back. Contact via online chat and pentax asked me to send into via e-mail for review. Two weeks later there is no response so I am calling them on the phone. And here is official response:
We reviewed all the cases of camera shake, EXIF info and concluded it is user error each time. I am free to send camera for repair as many times as I want provided I pay shipping but since problem is not acknowledged no repair attempts will be made. Pentax would not replace or refund full or partial purchase price since the problem does not exist.
Anyone needs white K-x kit for parts? :D
