I've had some issues with the EM5 shutting down after taking one shot. I turn the camera on and take a shot. The camera then pauses and shuts down. I flick it on and off and its fine. If it sits for a while off, I get the same problem again. I was using a 32 GB HP card, Class 10. It was filling up, but still had over 600 shots (RAW) left. I put a fresh 32 GB Sony card, also class 10 and formatted it but the problem still remains. I can still use the camera by turning it on, hitting the shutter, and flicking it on and off again, but this is obviously really annoying. No other problems that I can see? Any thoughts about what could be wrong. I bought it refurb from Cameta in August.
