Is this a problem the X-T4 does not have? I want to use it as a webcam too, for live streaming concerts for example. Does the X-T4 takes the power from the usb input or is it also draining the battery while using it with power on? Theres a dummy kit to go around this so thats ok for me but just found out it doesnt output is not Full HD ! WTF how is this even possible? I have one week to return the camera... does the X-T4 outputs full HD?
