- SR blur isn't consistent. There can be five perfectly sharp pictures and then something happens and SR blurs a few pictures.
- In slow shutter sutuations when I need to get 2-3 additional stops SR works. Not 100%, but works. It looks really weird when SR manages to get tack sharp picture at 1/10 sec (45mm focal length) however blurs picture taken at 1/180 sec.
Anyway, from now on I will keep SR turned off and will turn it on only when I really need it.
Your solution, to turn SR off most of the time, is the best workaround for now, I suppose. But, in my mind, it's ABSOLUTELY UNACCEPTABLE that this issue exists. I have the same problem with my K-7, and I'm quite disappointed (to put it mildly), as one of the reasons I made the switch from Canon to Pentax was because of in-camera SR. So now I have a camera that not only has ineffective SR, but one where you basically need to turn SR off to avoid blurry pictures. And I don't have the option to get in-lens IS, as Pentax doesn't do that.
I sent my camera in to get this problem fixed, so I really hope things will work out...
