Studio 15mm Minimount

"The 15mm Studio MiniMount will hold an articulating arm with its 3/8 16"" helacoiled socket. The MiniMount fits on 15mm Studio rods (100mm (Arri) spacing). When using a Zacuto Zamerican arm, a Zround Mount is necessary for mounting. By adding a Zround Mount the MiniMount becomes a quick-release mount.
