My new Pen F shuts down every so often. I can resolve the issue by unseating and re-seating the battery. I thought at first that it was due to a non-olympus battery but today I loaded the battery that came with the camera and it still shut down. I can take a couple of shots and then it fails to respond until I unseat and reseat the battery. It doesn't do it all that often so isn't a major problem but I have missed a couple of bird shots due to it. Has anyone else had this problem and how did you resolve it? OK I just googled it and it seems that quite a few people are having the same problem with the Pen F and E-M5mkll since the last software update.
