Moment Mobile Filmmaker Cage for MagSafe — Build a Pro Mobile Rig Without Carrying a Second Camera

The gist: A precision-machined aluminum cage that turns your MagSafe-enabled phone into a fully modular filmmaking rig — mount lenses, lights, mics, and handles without the weight or hassle of a DSLR setup.

• 28 x 1/4"-20 attachment points: Top, bottom, and side rails accept any standard grip, tripod, LED light, or follow-focus — the same thread system used on professional cinema accessories.
• (M)Force magnetic mount: Moment’s proprietary strong-magnet system snaps the phone in securely; swaps to a traditional clamp if you need extra security for action shots.
• Self-standing low profile: The cage sits flat on its own — useful for a quick tabletop angle without a tripod, and low enough to pack in a daypack without a dedicated case.
• Built-in cable management: Integrated slots route charging and audio cables cleanly alongside the cage instead of dangling across the frame.

Fstoppers called the Moment Mobile Filmmaker Cage “the best build quality seen in a mobile phone cage” and noted its modular simplicity makes it a go-to rig for mobile content creators.

Best for: Travel content creators, vloggers, and mobile photographers who shoot on MagSafe iPhones and want a professional rig without the bulk of dedicated camera gear. Skip it if: your phone lacks MagSafe compatibility or you don’t plan to add any external accessories — a naked phone plus a basic tripod achieves the same thing for less.
