Description
Designed for serious content creators, filmmakers, and mobile professionals, Beastmod is the ultimate cage upgrade for your Beastcage 16 Pro or 16 Pro Max. When your production demands more accessories, better mounting flexibility, and durability that lasts, this is the solution. Whether you're shooting a commercial, short film, documentary, or content on the go, Beastmod gives you the power to build out your iPhone like a professional cinema rig.
With precisely aligned 15mm detachable rods integrated directly into the cage, Beastmod supports standard follow focus systems, matte boxes, lens supports, and more. The rods are positioned to match the center axis of your iPhone’s main camera, ensuring compatibility with industry-standard gear.
Built from machined aluminum, it’s made to withstand the wear and tear of daily shoots while maintaining a lightweight, compact form. You get an abundance of 1/4"-20 and 3/8"-16 mounting points—all with ARRI locating pin slots—plus standard NATO rails on both sides for fast attachment of side handles, monitor arms, wireless transmitters, and more.
Do you need to mount it to a tripod or a cinema baseplate? No problem. The removable bottom plate includes a variety of tripod mounting options and dedicated mounting holes for ARRI BP-8 and BP-9 baseplates, with rods spaced to the correct ARRI height standard.
If you're building a fully tricked-out mobile studio or need a flexible, rugged base for any kind of rig, Beastmod is the cage upgrade you’ve been waiting for.
