Hello! I'm having an issue with my K-30 where the sensor is shaking during and immediately after an exposure. It is the same sound and vibration from the sensor, that the dust removal option creates, only it's happening during quick and long exposures. It is more noticeable in exposures >1 second, for every second of exposure time, there will be that many shakes/vibrations from the sensor, which throws the picture out of focus.
I have turned off the dust removal feature, reset all camera settings to default factory settings, and even installed the latest 1.06 firmware, and the shake is still present during exposures.
I searched this forum and found one similar user that had a similar issues, but don't know if there was ever a resolution other than sending it off for repair. Thread in question:

Has anyone else experienced this?
