The metallic slate gray Ellie-G Universal L-Bracket from 3 Legged Thing is Arca-type compatible with dovetail mounts on its vertical and horizontal components. Therefore, you are given the ability to switch between each axis while it maintains your center of axis. The horizontal base plate separates and adjusts from its vertical component to accommodate the length of the mirrorless or DSLR camera you are using, and there are two mounting slots to precisely position the camera on top of the base.
The horizontal base's rear slopes down so mobility is still accessible for the camera's LCD monitor. The vertical component is machined to have access to the camera's ports, and the component can be mounted in the reverse to allow cables to plug in from the right or left side. At the same time, the side plate can mount upside down so it creates a rocker mount for the camera. A strap loop located on the side allows for a hand or shoulder strap to be attached.
