SmallRig's HDMI Clamp 3104 is designed for their 2917/2918 cages for the Sony a7 III, a7R III, and a7R IV. The clamp attaches to the cage with a single included 1/4"-20 screw, and it secures your HDMI cable connector at the turn of a thumbscrew to prevent accidental disconnections. While the 2917/2918 cages also support other cameras, this clamp is designed specifically for the above a7 series cameras.
