Is anyone shooting yet with this underwater? Probably will get response from dealers as it is so new. But, I would like input on
1. Any overheating issues when shooting 4K?
2. Continuous/tracking autofocus performance when shooting video
3. How good is the IBIS for video--available in all modes incl 4k?
4. White balance
I am looking to move up from my EM-5 (mark I) and this looks like a top contender.
