There is no gyro. Sensor shift image stabilization systems use accelerometers, not gyros, to measure the change in motion.

The sensor does shift in the camera when it istilted- it isn't very much but it is noticeable. I think it feels like it moves more than it does because it affects the balance. It's connected to the anti-shake mechanism that allows the sensor to move and both my K100 and K10. It seems like the K20 might have something to stabilize the sensor whenthe camerais turned off- I haven't noticed it yet. Don't know about the K200.

Well, I went down to the electronics store and sure enough, all the Pentax dSLRs do the exact same thing mine does. Thanks for everyone's help in helping me solve this mysterious aspect of Pentax ownership.

Could it be the vertical/horizontal sensor that tells the camera if you're holding the camera and taking a picture vertically (portrait) vs horizontally (landscape)? So that when you review the picture in the LCD, it'll know which way to orient the picture?

That could very well be, too. They don't talk about it anywhere in the FAQ or troubleshooting guide in the manual. It doesn't appear to be a defect, though, and that's enough for me.
