K-5, MLU and SR

I was taking normal production pictures at work before Christmas. The resolution always has to be the best possible and because exposure times tend to be long, I use all the normal methods to reduce vibration, which normally means using tripod or the Manfrotto Clamp and Self-timer with 2 second delay (the mirror pops up reducing camera shake. I have used the 2-second-delay since the times of Z-1, when it became available.

When I took the first picture, the camera started shaking uncontrollably - the SR had activated itself obviously in the mirror cleaning mode - although the Info screen told that SR was turned off. The produced picture would have won the first price in a competition of earth quake pictures. The phenomenon continued until I returned to normal mode with SR on. No problem thereafter.

I repeated the situation afterwards, but the fault was not consistent - sometimes it recurred, sometimes not. In normal conditions there still hasn't been any single problem, but what happens in that kind of situation is that an uncertainty starts creeping in ones mind: "What will happen, if the K-5 invents some new behaviour just when I should take memorable pictures of my grandchildren by the Christmas tree?"

Well, luckily the prices of the K-5II series had just plunged. Now I am an owner of a K-5 IIs, couldn't be happier. Everything is just as comfortable as before, even the flash works as unpredictably as it always does with Pentax. But the AF - its now really something.

Anybody else met with this kind of fault with K-5?

Could it have been that your battery was discharged and did not have enough power? Congratulations on the K5 IIs - I'm envious!

My K-5 has always been reliable in the 2-second delay mode, but in the few days before I upgraded firmware from factory firmware, it crashed on a couple of occasions. I think I've only experienced one single bug since upgrading firmware (still at 1.13 though). Did you use the newest firmware?

I make frequent use of the 2-second timer with 30 second night exposures. Never experienced the shake you noticed because the 2-second timer always disables SR for me. You may have discovered an unfortunate interaction between settings that triggers a bug.

If you manually turn off SR while in regular shutter mode, then change to the 2-second timer, do you ever get the vibrations? That test might help narrow down what's happening.

If problems continue try a full reset to default settings.
