Hello,

I recently went out shooting with the irix 15mm and my K-1. I was shooting 3 brackated exposures, when in the middle of 3 exposures the camera locked up. Im not sure what caused it. It went away after i removed the battery grip and the battery inside the camera. The camera has a shutter cout of around 10k.
Any ideas what could have caused such behaviour?

Thanks in advance

As long as this only happens intermittently, it's nothing to worry about. Usually it's caused by dips in the voltage, and is thus more likely when either batteries are old/low or you draw a lot of power, such as from continuous AF and burst shooting. It can also be the result of low ambient temperatures combined with one the above.

Dont forget cameras today are computers. As such, just expect they might crash.

I've had my K1-ii for a few months now and it has done that a few times, though to me it happened during pixel shift shots and some times just in live view without shooting any picture. A couple of the times I had to leave the camera without battery for several minutes for it to recover as just removing it and reinserting after a few seconds wouldn't bring it to life. It would just make a loud click sound the first time the switch is turned on and then nothing happens.

Whether by coincidence or not I noticed that each time it did it I was using a rather old third party battery which I had bought for the K3 many years ago. I think this is in line with what Adam said about voltage dips.

I have since stopped using that battery on the K1-ii and haven't seen the problem again. Curiously that same battery still works fine on my K3, perhaps it is less demanding on the battery.

It's been quite a while but had a similar problem at one point well in the past. Using a manually focused third-party lens on an auto-focus body it would seemingly "short-out" from time to time. The first time it happened, I thought it was the end of the world! Discovered that I didn't get the problem if I switched the camera body to manual focus. That seemed to solve the issue...assumed it might have been the metal mount of the lens shorting out the autofocus tabs

Have you tried to clean lens mount? My K-S2 used to behave in the very same way, and cleaning of both surfaces of the mount (i.e. lens + body) solved the problem.

I have had the same thing happen but thankfully only once.

It was resolved with pulling the battery and putting in a fresh one.

The only thing that pointed me to the battery was it was very low and needed to be charged.

This sounds like very sound advice

Thank you for All the replies, i will look further into it. I think at the time i Was using some cheap 3rd Party battery so im guessing it has something to do with that.

It has happened to me, once. With my K5. I used a third party battery. I have never used that battery again, and haven't had the issue again with the K5 or the K-1. Coincedence?
