Videographers often want a cage around their camera so that they can hang lots of accessories (handle, external recorder, microphones, pre-amps, lights, etc.). While there are generic cages that would fit the Z's, you would normally want one that was designed to hug the contours of the camera body, both to minimize the the bulk, but also because this acts as a protective, structural housing in many cases.
Here are some Z cages:
- 8Sinn. Makes both a basic cage and a cage with top handle for the Z5, Z6, and Z7 cameras.
- Kondor Blue: Makes a cage for the ZR.
- Tilta. A full cage for Nikon Z5, Z6, and Z7 cameras. Tilta makes both the simple cage, as well as accessories that mount to it, most notably a quick-release top handle and a side power handle. They also make a modular cage for the ZR.
