50cm long Tether Tools cable, which can be used in conjunction with the Optima 10G TetherBoost Locking Extension cable.

The Tether Tools Optima USB-C Angle Adapter is a short, so-called pigtail cable for tethering photography. One end has a USB-C connector bent at a 90-degree angle on the camera and the other end has a straight USB-C connector. The angled connector allows the cable to run neatly along the side of the camera, making it easier to use a fixed strain relief and some accessories on the camera.
The pigtail cable is intended for use with the TetherPro Optima 10G TetherBoost Locking Extension cable.
Tip: If you shoot in a studio with multiple cameras, keep a pigtail cable attached to each of your camera bodies. Instead of having to repeatedly connect and disconnect long tether cables from the camera connector, the main cable can be disconnected from the pigtail connector and reconnected in seconds, reducing camera wear and minimizing downtime. This makes changing cameras on the fly quick and efficient.
