K200D interior movement

So it's been about 2 days since I bought my K200D ... loving it ... having trouble putting it down.

I've noticed that when I turn the camera on it's side it feels and sounds like something is sliding around in the body. There is a noticeable sliding sound and small clunk. My description is probably not that good ... but is this normal?

I've taken the lens off and batteries out and the same thing happens.

I don't remember noticing this when playing with the K200D or any other camera in the stores. Has any one else noticed the same thing?

Thanks.

It could be your anti-dust is on and its shaking dust off its sensors.

That's the sensor moving about, because the whatever-it-is-that-holds-the-sensor-in-place-when-making-an-exposures are inactive. It's completely normal, and every new Pentax model does that. Nothing to fear.

exactly!!! the sensor is held in place by electromagnets that are only active when the power is on. If you shake your camera with the power off you can hear/feel the sensor move. I notice it a lot when I'm walking with it hanging in my hand.

This should be on the first page in the user's manual.

Has anyone NOT felt the "klunk" for the first time and and wondered?

Page two should be how to use lenses with aperture rings.

Page three explains the "buzz" sound with long exposures and SR on.

Page four covers the "sigh" sound after multiexposure and SR on.

Page five explains focal length and APS-C format sensor. Without the marketing garbage.

Enjoy your new camera, and welcome.

Haha ... I totally agree! The "buzz" sound was my next concern.

I don't think that's the official name in the manual, it's something like long exposure noise reduction. If you take a photo with a long shutter speed, you'll notice that you can't take another photo right away. The camera takes a second photo with the shutter closed for the same length of time, the "dark frame". Then it subtracts anything in that photo (which is pretty much noise from the sensor) from your real picture. When you do your first 15 second exposure, you usually get surprised that the preview doesn't come up, then wonder what is wrong, then panic that your camera is broken, all in the 15 second dark frame time. I think it can be turned off on all the models except the K20D.

Ah yes, I had heard mention of something similar before. Wasn't aware of the use of a dark frame though. Thanks for the explanation.
