SmallRig Ultra-Slim 4K HDMI Data Cable (A to A) (55cm)

The SmallRig Ultra-Slim 4K HDMI Data Cable (A to A) 2957B is a high-quality HDMI 2.0 cable purpose-built for professional camera rigs. Designed for DSLR and mirrorless cameras, monitors, and wireless video transmitters/receivers, it supports resolutions up to 4K at 60Hz while maintaining a compact, flexible form factor.

With an ultra-slim 3.6mm outer diameter, this cable is noticeably thinner and softer than standard HDMI cables, making it ideal for tight rig builds. The low-profile connectors help prevent blocking adjacent ports, while the 55cm length is perfectly suited for on-camera monitors and compact video setups.

An included cable tie helps keep your rig clean and organised.
