Clunking- Worry or Not to Worry

[Didache]

You CAN turn it off if you want .. and you will get no clunking. Test it like that if you want just to reassure yourself.

This is from a pentax forum:

"While playing with the menu of my new K10D on Thursday night, I set the dust reduction setting to the "power on" position. Made a few other changes then shut the camera off, watched a little TV and went to bed.

Yesterday, during a lull at work, I took my K10D out of the bag and turned it on. "What's that vibration and horrible noise?", I said to myself. Turned it off and on several time and each time it made the same noise and had the same vibration.

Well, I thought something had gone terribly wrong with my beautiful new camera so I called Pentax tech support and explained the problem. The techie was very nice when the question was asked "did you just reset the dust removal to operate each time the camera is powered up?".

I said "Yes", thanked them and hung up the phone.

Well "Duh-Huh", was I ever embarrased."

Cheers
