K10D OMINOUS FEEL AND SOUND OF HEAVY OBJECT MOVEMENT INSIDE BODY

After more than 50 years of film photography I have bought a used digital camera body. Cost of film, paper and developing beyond me having just retired. As you can imagine I have more than a dozen various lenses all with their own success and limitations on my K10D
As you can see from the title I have a worry. It doesn't move far - just enough to be obvious that there is play in something and it feels like something quite substantial. Apart from flash always whiting everything out and a few unaccountable reciprocity probs the camera appears otherwise ok.
Has any one any comments please ?

In regard to actuations, I got nothing from Photome but in top right hand corner of info is 100-7269 does this imply 726,690 shutter releases ?

If the heavy object is only noticed when you switch the camera on, it could just be the sensor cleaning operating.

have a look at this link it should give you the shutter count

100 is the folder name. It implies 7269 shutter releases. When it reaches 9999 the next step will be folder 101, which will start from 0001. Then folder 102, and so on. Nothing to worry about.

A thunking noise is probably the sensor assembly moving, until such time as the camera is switched on and the SR system takes command of it. Again, nothing to worry about.

Thank you both

Unfortunately the thunk occurs when switched off and when switched on and with SR on and off. I noticed it the first time I tilted the camera from landscape to portrait while taking pictures. Testing it again now it is doing it when tilted on its axis in the same plane in use. In other words not laying it on its back or front.
Just did sensor cleaning and could hear something going on and the clunking did not happen on moving camera. however, now cleaning finished and camera back on, the clunking is still there.
I suppose if all else is working I should ignore it. Probably nervous about just spending £100 on my first digital.
Thanks again

If it's all working it's no doubt the SR system - the sensor array moves. So just enjoy it, you've spent £100, but that's a bargain compared to the pleasure you should untilmately get from using the camera.

Thank you bforbes for the link.https://www.camerashuttercount.com/
I uploaded an unedited pef and it returned a result of 37,064 on Pentax K10D so it got the camera right.
D'you reckon the counts right ?

My K10 has always made a thump when shook. It also makes a similar noise when the startup clean is set.

I bought it new and it got a lot of use until I bought the k5. Don't worry, mine has had a lot of rough handling on days in the mountains but has never missed a beat.😁

My K10 has taken 32,000 pictures. I believe Pentax cameras of this generation should last for c.100,000 shots.

My (ex) K10D did the same when tilted, it's normal and is part of the SR system, nothing to worry about.
It actually mentions it in the handbook

reply to an old post i know, but Hey ! i'm new to the site and have a lot of catching up to do.

My K10D has 7005 actuation's as of 18-09-2017 and mine does the same. No Worries.
