SmallRig SR4391B Mobile Video Cage for iPhone 15 Pro Max

Turn your iPhone 15 Pro Max into a more versatile mobile filmmaking setup with this compact and lightweight video cage. Designed for content creators, vloggers, and live streamers, it adds secure mounting options while keeping your phone easy to handle and fully accessible.

Built for creative shooting

With multiple 1/4"-20 threaded holes and cold shoe mounts, you can attach essential accessories such as a microphone, LED light, handle, or tripod with ease. The quick-release ecosystem makes setup faster and more efficient, so you can spend less time assembling and more time filming.

Flexible lens and accessory support

This cage supports an M-mount lens, and with a rear plate swap it can also accommodate 17 mm / 37 mm threaded lenses and Moment T-series lenses. It also includes strap openings on both sides for straps under 2 mm in diameter, adding another layer of convenience for on-the-go shooting.

Designed for full phone access

Thoughtfully cut out for everyday use, the cage leaves all buttons, ports, radar functionality, the ultra-wide lens, and MagSafe wireless charging fully accessible. You can shoot in both horizontal and vertical orientations without interference.

Durable protection with a secure fit

The all-metal construction offers a stable, reliable feel, while built-in pads help protect your phone from bumps and scratches. The quick-lock and release design is also engineered to reduce the chance of accidental opening, giving you extra peace of mind during use.
