In June 2013, I sold all of my Nikon gear and bought an OM-D E-M5 and Panasonic 12-35. Last week, while in Mexico, the camera stopped working. One minute it was fine, the next minute it wasn't. Every time I turned the camera on, it would remain powered for 6 - 7 seconds and then shut down. While it was "on", none of the buttons worked. The rear screen showed a live view but none of the usual information was being displayed (aperture, ISO, etc). The live-view image also shifted color balance from yellow to natural white, as if it was warming up. I tried using my spare battery and SD card to see if one of those was at fault but the result was always the same. I suspect it's a software issue. Anyone else having the same problem??? Any suggestions? Thanks, Dan FYI... I've been shooting since 1977 and have owned many Nikon, Canon, Olympus and Fuji bodies and lenses. I've had most of my gear serviced over the years as a preventative measure but this is only the second time I've ever experienced a serious problem (the first was an autofocus motor that crapped out in my Nikon 17-35 f/2.8).
