I've had my K-5 for about a year now, probably 30k shots on it, and it froze on me twice last weekend while I was shooting a mountain bike race. Just like you said: LCD frozen in the on position, had to pull the battery out and back again. I was using the AF-C more than I normally do, so maybe that's it, but it had only frozen on me once before then, when I was shooting wildlife a couple of weeks ago. Since I have to pull my battery grip off and re-mount it these freezes are really annoying. Anybody have any idea on a solution?

I'm running firmware 1.13, so nothing there seems to help. Shooting exclusively with Class 10 cards too.
I've already returned one K-5 during the two-week store exchange period, because of the Live View mirror lock-up freezing issue. So this is my second K-5, and the Live View freezing issue has not occurred with this body.

But I've been shooting my son's soccer games for about a month of weekends now, on this (second new) K-5 in high-burst continuous mode, AF.C, TAV, DA 50-200 WR lens. About 7560 shutter actuations as of today. Capturing RAW files only. Firmware V 1.12 this morning, but after today's experience, I've just upgraded it to 1.13. SR was also on (yes I know sports shooters say it shouldn't be used but it's a habit).

Today, the temperature outside was ~15C (with a "RealFeel" of 18C according to Accuweather), partly cloudy and windy. And today, I experienced for the first time, and not just once, but twice, the OTHER freezing issue that people on this thread are describing.

The first time the camera froze today, I saw in the viewfinder the red square of the focus point, which then remained 'stuck' in the viewfinder while the shutter release would not trigger. The top LCD displayed all of the current settings. Turning the power off then on did not unfreeze it. From my earlier Live View issue, I knew that I had to remove the battery and reinsert it. The camera reverted to settings that I'd had the first time I'd turned the power on this morning, but did not retain the settings (shutter speed, EV compensation, aperture) that I'd set it to before the freezing occurred.

The second time, I'm sure I was simply following the action with the lens and keeping my finger half-pressed on the shutter release button to keep the action in focus and getting myself ready to time a shot. All the while the autofocus was adjusting and readjusting as the moving subjects shifted around the field with the ball. Mid-focus, the camera froze again (with the mode & autofocus settings described above) and again turning the power off then on did not resolve anything. I had to take the battery out and reinsert it.

Altogether I took about 760 pictures at the soccer game, on a Lexar Class 10 32GB card. The original Pentax battery I used in the camera this morning still shows a full charge (and this is the end of the day as I'm writing).

I also noted that when I arrived home 30+ minutes after the soccer game the camera still felt hot around the handgrip (I am not using any extra batteries or grip).

This afternoon my son went on to play baseball but I was reluctant to pull out the camera after having to fiddle with the camera freezing and battery this morning (besides, the home field has so much chain link fencing around it I find it a bit of a hassle having to find good vantage points ... but it's been a long day of driving around between home and various fields).

Has anyone who's experienced the freezing issue in high-burst, continuous AF.C shooting sent their body back to Pentax for repair (ie. from what I read here this now seems to be a common enough occurrence and should not be news to Pentax), and if so, does the repair resolve the freezing?

My first camera was purchased in Feb 2012 and exchanged for the second one early in March. The second new camera had no other issues such as the Live View freezing I'd experienced with the first camera, and is well within its original warranty period. I'm wondering if anything else can be done to avoid the hassle that I've just experienced today. This is my first dSLR, and none of the other digital cameras I've used (Canon, Olympus) have frozen up like this.

Is there any advantage to me in getting Pentax to look at it? Thanks in advance for any advice or experience ~ Katherine

Same problem. You describe my experience too.
I just posted in another thread, but i'm going to bump this one too because this issue is very annoying for those of us who have it.
https://www.pentaxforums.com/forums/pentax-k-5/174933-k5-lock-out.html#post2011927

8Gb class10 sandisk and transcend cards
firmware v1.13
68000 actuations on one body
2400 on another
I am using a battery grip - i don't think it has ever happened when i wasn't.
Battery selection set to auto, but i have also used it set to 'grip first' for a long time too. Obviously this is preferential when using a grip.
I have a combination of aftermarket and pentax batteries, but it happens on both. I generally don't mix the two types when using the grip.
The batteries always have a charge, and iirc it's never happened on a fresh full-charged battery. I get the feeling it's mostly when the camera has almost consumed one and attempts to switch to the other, but there is always some (at least 1/3rd) charge left in both.
I feel reasonably certain that one manifestation of this problem relates to the presence of a power grip, or as someone else found: DC input.
K5 Camera Freeze?: Pentax SLR Talk Forum: Digital Photography Review

Camera is usually set to AF-C or M but i am always using manual focus and usually manual aperture lenses, so the position is irrelevant to me and i therefore pay no attention to it's position. I have the focus confirmation set only when i press the AF button anyway. Which is practically never.

I never use liveview. Auto preview is disabled. I preview manually, but not very often. So the LCD gets used, but rarely.

Seems unliklely it's thermal, I have had it happen on cold days, cold camera, and only shooting infrequently, just as I have been standing in the sun in Australian summer for hours machinegunning faces as they pass. I don't think there is ever much variation in the sensor temps the exif reports, but I probably should check that.

This is not just a mild inconvenience. It's very frustrating.
There is only one or two things I find unattractive about the K-5 functionality, and this is absolutely at the top of the list. On those days when simply reinserting the battery doesnt fix the problem it's a showstopper category problem.
When it happens to two bodies from two very different batches on the same day. It's a "resist urge to smash camera on the ground" type of problem.

no lock up and I use a battery grip ,[ albeit a pirate one which was sold for half the pentax price], with only a battery in the grip, as I have yet to use a battery up and need to change it at a wedding which is when it gets the most use.

The only time it happened to me when when I was using a battery grip with aa's. The battery grip is a cheapo one and not very good, so I blamed some glitch in the comms between grip and body. I removed the grip and battery in the body and it was OK. Never happened again, but I am saving for the OEM grip. Actually I use the grip less than I did the one for my K20, but that is another matter. Anyone had the af-c fast fps lock-up without a grip attached?

Yes, if you read my post #16, you'll see that I don't use any battery grip on my K-5 at all.

First time freezing occurred on brand-new K-5 while LiveView was engaged.

Second time (and third time) on a new, replacement K-5 from the store, when camera was on AF.C, high burst shutter mode.

Battery OEM, battery level appeared full at the end of the day after the second and third incidents of freezing.

Well that theory goes out of the window then. I have not had another lock-up incident so I can't comment further till I do...I ahve also recently upgraded firmware to 1.13 so another variable to consider, these intermittent faults are always a pain to track down, and in truth there may be several reasons /situations that can cause it.

Yeah, I can't be sure but I don't recall ever seeing it happen in earlier revisions.

Freeze on shutter relase

Hi Guys,

My issue is similar but it freezes on shutter release. On releasing the shutter button you can hear the shutter release but it just freezes at that moment. I have to take the battery out and re-insert. Once i restart after re-inserting the battery you can hear the shutter release but nothing is captured. It happened today, i had been taking quite a few practice shots. anyone else experiencing this?

cheapo battery?
I have it happen with original pentax batteries and a variety of others. IIRC It began happening before I had used any third party batteries.

Shutter locks : agreed. I think everyone experiences this lockup when the shutter activates. Generally I turn the camera off, and the image is never saved.

Happens during multiple shots: agreed. I mostly shoot in 2+ shot bursts, but I think it might have happened to me in the past when I had only fired a single shot. However do not recall it happening on the first shot fired after a period of several hours inactivity.

Can hear shutter releasing: maybe. Somethng does make a sound while the camera is attempting to shoot but locked. It sounds like the sensor SR is being moved a lot, or more likely that the shutter mechanism is attempting to open the curtain and failing. I say failing because my cameras make a very different sound when successfully taking photos as compared to when the camera is locked up.

Next time mine does this I will more closely inspect things like if the mirror is moving/locked,shutter curtain actuates or not, etc.
Previously I have just been concerned with making it work again immediately.

Well it's continued happening over the last couple of days, and it's become obvious that it's usually a mirror jam issue. The shutter is not usually left open (although I think I have seen it do that too) but the mirror stays up. It can be easily moved with fingers, but just springs back up when released.

Today I had only just begun shooting and it became obvious that removing the battery and waiting for a while wasn't going to make it work.
So I did the obvious thing: I told the camera "Work or f*****g die!" and gave it a fairly careful but firm sideways thump with the heel of my palm.
The mirror popped back down, I thanked it, and it continued shooting the rest of the day. (~1500 shots).

Knowing how to unjam it is good.
Actually unjamming it is probably a bit bad for the camera.
Being able to unjam it is great.

Given that the official repairers in Australia refused to even fix a *manufacturing defect* (sensor stains) because I had shot more than 20k actuations (or whatever it was that they prominently stipulated on the warranty return form), I wouldn't even ask if they would fix this under warranty, even if it was still inside the 12 month period.

Currently feeling vindicated about buying a second greymarket K5 via Hong-Kong for nearly half the price of the first locally purchased one.. and it's lol-warranty.

Interestingly, since I thumped my camera I have shot ~7400 frames on that camera and not had any lockups. Not one.
Fingers crossed that's how it will stay.

I used to have camera freezes all the time with my Samsung EX-1. The culprit: the SD card. Not that the card was bad, it worked great in my older cameras and computer, but the EX-1 just didn't like it. Not all SD cards created equal. Changed card brand, and never had a freeze since !
