3 Make fun of Thing have been showcasing a new bracket range as well as a wide range of tripod and monopod accessories at Photokina.
The Zelda division has been specifically designed for the Nikon Z6 and Z7 cameras. The articulated arm which can be seen with the Zelda doesn't have a name yet.
There's also the Ellie L class, which is a more universal bracket that is compatible with Arca Swiss, but also has tapered edges so that you can still access the argument screen on your camera. The side bracket can be repositioned, depending on where you need it, to give you side access to the ports on the camera.
