^No, I only did the standard firmware upgrade. Reverting back was easy and it's a known working version for myself so I'm satisfied with where I'm at. My co-worker has the same camera and is experiencing the exact same issue with the new firmware. If you watch the seconds count by in live view you'll be able to tell if you are having the same issue. Instead of counting normally (1, 2, 3, 4) it will be more like 1, 2....456, 7, 8....12, 13 if that makes sense. If I'm feeling ambitious I'll try again and then do a factory reset and report back.
