I’ve purchased this item for live streaming with my Panasonic Lumix GH3. As you may know, GH3 doesn’t have a setting to cancel battery saving, as a result camera shuts down automatically after 5 mins, which is very annoying. There is a bug to get over that situation (set the camera to timelapse mode while it is connected to capture card eith hdmi out) but if you use this dc coupler you dont need those bugs.
Thanks AAA+
