Hi there. I just bought a used (but in mint condition, just purchased in one month less than 2000 clicks) K-3, after test tens of clicks I upgraded its firmware from 1.00 to 1.11. After that till now (only 2 weeks), I've met 4 times of failures in 2 kinds, within around 3000 clicks (most in burst mode to shot some basketball plays and my daughter) . One of them seems not ever be reported here (or I missed it in searching), so I report here in a new thread. Any suggestion will be appreciated gratefully.
This is the basic info of my K-3:
Manufacture Date : 2014:03:10
Production Code : 2.1
Internal Serial Number : 7044085
Power Source : Body Battery
1. K-3 stuck in review mode, it didn't response to any operation, even turning the power level to OFF. At last I've got to pull the battery out, and after I pushed it back and power on again, all the settings I modified during the stuck session and pictures in the buffer was lost.
This failure happened twice. Once I was checking pictures while it was storing pictures (SD led was light), after took around 10 clicks during burst mode . After I check couple of pictures, I found I couldn't move forward or zoom in out anymore. Then I tried to half push shutter or turn off the power level, nothing happened, it was still show the same picture. At last I had to pull the battery out and push again, then all the 10 pictures were disappeared.
Settings was in AF.C, all auto focus, matrix meter, H drive mode, TVs F5.6 1/250, no flash, FA*85/1.4, white Toshiba 16G class 10 SDHC card in slot1, JPG L high.
The second time happened to FA*24/2 lens in AF.S, single drive mode, similar condition. The most difference from first time is this failure also happens in single drive mode / focusing mode. At that time there was only one picture in buffer.
2. The other kind of failure I met is mirror lockup while burst mode for less than 1 second, then camera reset internal. I even didn't notice this failure, until it got wrong exposure next click, because the settings I modified was lost during internal reset. Similar settings with first failure. The info of last saved exif is:

I cann't tell whether this failure is same as the Mirror Lockup issue in this forums, since my mirror was just locked less than 1 second, and camera reset itself.
Hoping this will help to Pentax to solve it.
Best regards,
