I am shooting down in the Cayman Islands currently. We got our c300mk3 a few weeks back and was working great. The other day while shooting, it started acting strange I.E buttons not functioning as it should, would not record etc. So I powered down the camera and it would not turn back on. There were no overheating warnings, the camera was not in direct sun and it was not an overly hot day. We tried everything to get it to power on again and nothing worked. So now we have had to send it back to Canon U.S for service which is unfortunate. I will update once we here back next week on what happened.
