Im having cruddy luck here. I have a Panasonic GH3. Love the camera, Have a Switronix Pro-x battery that uses power tap connections. I bought the GH2 powertap to DC female connector and when I plugged it in to my GH3's DC coupler, the camera won't power on. What's going on? I don't seem to see anything else from Switronix. Is the GH2 adapter not compatible with the GH3?
