I took my new K5 out for its first real outing today and when I used the burst shot every now and again the shutter would jam happened several times anyone else had this problem ?
This being my second K5 Im thinking "Not another One surely "
All the best

shutter "Jammed" or memory buffer full? I'm inclined to think the latter, as the former sounds like the kind of thing that happens "ONCE" before going in for repairs...

could be some custom settings (ca and lens corrections) shooting RAW, or slow memory card...
Fired many shots. Didn't kill anything.

Could it have been the buffer filling up and preventing any further exposures?

I doubt it john but hope its a strong possiblitly the other issue was stayed jammed until the battery was taken out and put back I have had the thing you refer to and is common and just delays things but this will stop everything dead,the top lcd stays jammed as well nothing I can do will change it even turning the camera off wont have any effect so I think I have a problem but hope I have not but doubt I am wrong on this occasion
I will get in touch with my retailer in a while and go there after Easter and get this sorted, its not the retailers fault but I only want the wonderful K5,despite its issues I believe its the best,Im no expert agreed
Here is hoping and thanks for the suggestion John
All the best

can you try a different memory card in the mean time? check for firmware updates?

Thanks Don firmware up to date and I changed the memory card twice and the battery once the sympton isnt like a buffer issue its a firm Jamming with a jamming shound and feel I tried what I think (within my limited knowledge everything I could think if but nothing have had buffer issues and firmware but none like this it almost felt mechanical but this could be the feel and noise of the shutter stuck
Will try it tomorrow and just set it up with no particular target and fire shots off to see if and how regular this is but dont want to cause possible damage...
All the best

what is your camera settings for powering itself off?
these guys found turning the "auto power off" to off worked around the same issue...link

I hope this isn't a stupid question, but does the K-5 ( and for that matter the K-20D and K10D, etc ) actually have a mechanical shutter? When I change lenses I can see the sensor behind the mirror. Is there any need for a mechanical shutter with a DSLR?

I cannot see how that is possible... if the mirror is down, then you cannot see behind it, you'd see a reflection of the focus screen and maybe the view from the eyepiece..
if the mirror is up (say for cleaning) the shutter would be open...

the focal plane shutter is soon to be obsolete, replaced by global shutters or dlp mirrors in future cameras...

It actually happens to quite a few K-5s, the camera totally jams and the LCD stays on even if you switch it off. As you found out the only way to cure it is take the battery out (very annoying if you have a grip attached because you have to take that off as well).

Just add it to the list of K-5 "quirks"

I dare not say quality issues as Pentax rarely has those.

They certainly do have a mechanical shutter. Look into the mirror box with no lens attached, and operate the camera with the mirror lockup enabled. You'll see the shutter.

Hi I will have to check as to what the factory settings are as I have not set anything up in the menu but will check it out but should not happen odd and a little disturbing
All the best

I think the factory setting may well be 1 minute, which would be very annoying. I usually set 30 minutes so the camera doesn't keep switching itself off.

That sounds like a firmware issue. A branch without a return methinks. (Guess how I know about them. :blush

Thanks John it was set on 1 minute I will try the 30 minutes and see if it works in this case ...sounds hopeful

I will post the results later for reference ,here is hoping

With the contributions here I am hopeful at least which at the moment is a relief

All the best
