The Cineroid HC-5D HDMI Clamp for 5D MARK II/III/7D/D800 Cameras is a clamp designed to protect the HDMI port of a DSLR camera. The clamp holds an HDMI cable tightly, avoiding damage from the the outside of the cable and connector of the camera. This HDMI Clamp is compatible with the Canon 5D MKII, Canon 5D MKIII, Canon 7D, and Nikon D800 cameras. It allows access to all camera functions and controls without removing the protective plate. The HC-D5 features a wide surface area at the bottom of the camera to increase stability and help minimize flexing of the camera body. The HC-5D can also be used as a small handheld rig with monitor arm. It is suitable to use with an EVF viewfinder as a portable video device. It can be attached to any other accessory using the 1/4" screw mount.
