A micro HDMI to full-size HDMI cable for running video from a camera to an on-camera monitor, external recorder or display. A coiled cable that stretches when you need slack and pulls back out of the way when you do not. The slim OD3.2mm jacket stays flexible on a rigged camera or gimbal, so it does not fight the build or put leverage on the camera's HDMI port — the connector most likely to break on a working camera. Carries a 4K signal for monitoring and recording. A sensible spare to keep in the bag, because a failed HDMI lead stops a shoot dead.
