Hiya folks -

Just got this one today. Even without mounting the lens, when I turn the body upside down or fully sideways, something inside seems to move a bit making a slight 'whoosh'. Is that normal? If so, any idea what is moving inside/?

If it is an issue, I can still return it for a replacement. So I appreciate your inputs.

Cheers!

The sensor moves as for Shake Reduction (SR), composition adjustment and astrotracing. When the camera is powered off the electromagnetics that hold and move the sensor are de-energized so the sensor can move around. This should be normal.

Common 'issue' a lot of folks see. It's the SR module sliding around - it's an active piece so not held in place when the camera is powered off. Perfectly normal behavior - your K-1 is fine

Edit: haha, too slow posting here, you beat me to it Not a Number... guess it's still a post towards the giveaway however

The Pixies can't work when the camera is turned off. Don't shake the Pixies!

LOL.
Phew! Thanks for the confirmation Steve, NaN and bertwert.

And yes - I won't shake it. Just noticed the weirdly soothing whoosh when I happened to turn it upside down to insert the battery.

To add to the others' comments, the sound caused by the SR mechanism is mentioned in the Operating Manual, page 8. They call it a "rattling sound."

Enjoy your new camera!

Ah, the manual. Should RTFM first :-). It was too tempting to just rip open the box and start shooting.

Moving the sensor (for SR, pixel shift, anti-alias, astrophotography, composition adjustment) is a wonderful thing. Treat it with reverence.

No worries. The notice is easily overlooked in the first couple of sections of the manual.

One of my early girlfriends was like that................but the forum rules prevent me from discussing it here.

Edit - But back to topic, yes, the little SR " clunk " is normal. Enjoy your new camera, and hope to see some pix soon..

Pentax camera sensors are mounted inside the cameras like drums inside washing machines. It's designed in such way to apply a strong gravitational force on the photographer to stabilize him (or her) when he(she)'s about to take a picture

Don't worry, you're not the first, nor the last. I'm sure we can all relate

A very common concern but totally normal!
