Brandon Li Mobile Video Cage for iPhone 15 Pro Max
The SmallRig x Brandon Li Mobile Video Cage for iPhone 15 Pro Max Co-design Edition is a multi-functional iPhone cage specially designed for iPhone 15 Pro Max, helping to realize high-quality video recording, live broadcast, and vlog shooting. The compact cage weighs only 85g. It features 1/4"-20 threaded holes and cold shoes to attach the handle, tripod, microphone, LED video light, etc., which is made easier and faster with the brand-new quick-release ecosystem. On both sides, there are strap holes for straps less than 2mm in diameter. It allows mounting an M-mount lens or, by replacing a backplate, a 17mm / 37mm threaded lens, Moment T-series lens. It is subtly hollowed out to give full access to all buttons, ports, radar ultra-wide-angle lens, and MagSafe wireless charger. The easy-to-use quick locking and release design is safer and more stable, preventing accidental unlocking because of mistouch. The all-metal full cage also comes with built-in pads to avoid possible shocks and scratches. Putting on this cage would not interfere with your ability to take horizontal or vertical photographs.

SmallRig x Brandon Li Mobile Video Cage for iPhone 15 Pro Max — The Travel Filmmaker’s iPhone Rig
The gist: A filmmaker-designed, 85g aluminum cage that turns an iPhone 15 Pro Max into a fully-fledged video production platform — cold shoes, 1/4“-20 threads, and a quick-release lens system, all without blocking MagSafe or any phone port.
- 85g aluminum build: Full all-metal cage at 85g — light enough to handhold all day without fatigue; adds meaningful rigidity to protect the phone during demanding shoots.
- Multiple cold shoes + 1/4“-20 threads: Attach a mic, LED panel, external monitor, and handle simultaneously — the full production accessory stack without needing a separate baseplate or rig.
- Modular lens mount: Accept M-mount lenses or swap the backplate for 17mm/37mm threaded adapters or Moment T-Series lenses — wide, anamorphic, and macro options without a clip-on adapter.
- Full port and MagSafe access: Precisely hollowed for all buttons, charging ports, ultra-wide lens, and MagSafe charger — no need to remove the cage to charge wirelessly or adjust audio.
