Camera Internals Moving?
Thank You for your reply, that's put my mind at rest Now to start learning how to take half decent pictures.

It's nothing to worry about. Both the K100D and K10D have a shake reduction system and they both make that same noise.
Is this definitely what it is?
SR must presumably consist of several lightweight bits that respond quickly, whereas the 'internals moving' sound that I've noticed from the K10D is more of a 'slow slide' - something sliding over something else - as you slowly rotate the camera about its lens axis.
I've speculated that it's something to do with the orientation sensor - does the K100D have one of these too?
It feels like the metal chassis is sliding up and down slightly.

The whole plate with the CCD has to move under magnet control. When the power is off and the magnets aren't engaged that plate can move on its own... well, when you turn the camera upside down at least

I dont think this is the SR system that is moving as this slow slide occures even when the K10D is switched on.
This is more likely to be the Orientation Sensor that you can feel/hear moving and yes it is also apparent on my K10D.
Although I'm sure its nothing to be concerned with as there are many reports of this noise.

Hi travellingmanjim,

The orientation sensor is no more than a tiny ball bearing. What you can hear is more likely to be the dust removal system, which you can turn off.
I feel the same on my K100D, and a GX-10 as well. It seems like a heavy part on the inside is sliding, I'd be surprised if that is really the sensor plate - should need some very strong magnets to keep it floating during a shot.
I've just sent an e-mail to Pentax UK asking about this. I feel better knowing that it's not just my camera (may be a design "feature", but it's better to ask
Please pay attention to the original post, he has a K100D, not a K10D.
We knew that
It's just that Pentax's SR technology is the same in the K100D and the K10D.
And it is the CCD on its plate.
should need some very strong magnets to keep it floating during a shot.
Absolutely. Ever had an old hard disk apart? Tried the magnets? Scarily strong. The SR technology uses a similar voice coil to hard disks, and presumably similar magnets.
But, all the same, it'll be interesting to hear Pentax's reply
