Vibration using bulb setting on Pentax K10D

Hi,

When I use my Pentax K10D in Bulb setting it makes a sort of ticking noise and produces a vibration which causes the effect like a heart trace seen in the picture of the car lights. The vibration is severe enough that if the camera is placed on a table it can be felt by placing your hand on the table top. Does anyone have any insight as to what is causing this and more importantly what if anything I can do to correct it please?

Many thanks in advance,
Chris

Hi Chris in the handbook it recommends that you turn off the shake reduction when using a tripod. It might be the shake reduction working ?. Derek

Hi Derek,

Afraid not but thanks for the suggestion - I'm hoping it is something simple like a setting.

Regards,
Chris

On a tripod I use the 'mirror up then 2 second delay' option in the drive settings. Plus no shake reduction as suggested. Your problem does sound a bit odd though.

Hi Mike,

It does have a mirror lock up facility and it has exactly the same vibration when I use it.

Thanks,
Chris

Not all the EXIF information is contained in the file you have posted (it's been pulled out by Adobe PS-CC). I could have sussed most of the required info from a full JPEG or RAW file.

Just tried the same action on a K10D here. No real difference between SR-On and SR-Off. I suspect SR has been disabled in Bulb mode. I can hear the magnets energised, making a very quiet purring noise - presumably as it keeps the sensor centred.

Do check what firmware version you have (I have v1.30).
Hold MENU down while powering up

Hi Mike,

Thanks for your comment. It seems I am running version 1.0.
Having played with it for a bit I suspect the dust removal may be activating for some reason. I've tried deactivating it but still getting the same ticking so I could be wrong.

I tried to upload a RAW file but the uploader informs me it's the wrong type of file.

Regards,
Chris

Hi Chris,
I suggest you download firmware v1.30 and update your camera. Pretty sure there were SR issues that were fixed

See the Instructions and download the Windows installer
