The Xtender CSM-20 Shoe / Microphone Mount connects the Xtender articulating arm to your camera's shoe mount. With the mount, you can fit in a 5/8" threaded mic clip to connect a microphone directly to your camera or connect the Xtender articulating arm to the camera by coupling it with a CSR-10 shoe receiver. It also converts the shoe of your camera to a 1/4-20" threaded mount.
