While I'm doing my personal experimentations with my new Sony A7Rii camera, I came across several mentions of sudden shutdown when the camera is left recording 4K video. This is due to overheating. In other words, it's no Panasonic GH4--which can seemingly record forever until its fantastic battery life (something I really missed!) drained or your memory card got used up.

Alarmed and disappointed, I figured I would do my own experimentation and set up the A7Rii to record in 4K on a tripod. The difference between my attempt and others' attempts? Mine has entertainment value in the form of my trusty bikini model Kelly. :) See video above.

I shot in Super 35 mode (better video/noise quality in low light), and at 30 fps to help tax the camera. I used the Sony 28mm/2.0 lens. I forgot what ISO...between 3200 and 6400?

Long story shot, it seemed to reach the 29- or 30-minute limit before video recording stopped. Then I started it up again no problem, at which the A7Rii proceeded to record an additional 12 minutes before shutting down. Not bad, I'll take it as I've heard much worse. I did pull out the rear LCD screen away from the body, that supposedly helps. Still, if Sony would solve the overheating issue in the future, then it would be a nice piece of mind if one needed to video record at 4k over extended periods of time.
