SmallRig 5542 Mobile Video Cage for iPhone 17 Pro Flagship Edition

SmallRig 5542 Mobile Video Cage for iPhone 17 Pro – professional expansion solution for video, live streaming and short films

This kit delivers a professional expansion solution designed specifically for the iPhone 17 Pro. It supports professional-level video recording, live streaming, and short film production by providing a modular cage, protective case, and accessories that let you add microphones, lights, lenses and mounting hardware.

Key features and benefits

The SmallRig 5542 combines protection, expandability and quick setup. In everyday use, the included case protects your phone while also working as the interface for external lenses via a T-mount backplate or the optional magnetic adapter. At the same time, the all-metal cage offers multiple mounting points and quick release interfaces so you can move quickly between handheld and tripod setups.

Modular backplates and lens options

The case comes standard with a T-mount backplate and a 17mm threaded lens backplate for attaching external lenses. You can replace the T-mount backplate with a 67mm magnetic filter adapter (sold separately) to change or enhance optical output. These options let you adapt the system to different shooting needs and lenses without altering the core cage.

Mounting, accessory expansion and straps

• The cage features multiple 1/4"-20 anti-twist threaded holes for secure accessory mounting.
• It also includes cold shoe mounts for microphones, lights and other shoe-mounted accessories.
• Classic quick release interfaces allow efficient transitions between handheld and tripod setups.
• Side-mounted strap holes accept professional wrist and shoulder straps that are under 2mm in diameter, keeping your hands free between shots.

Protection, access and special-use modes

The all-metal construction provides protection, shock absorption and scratch resistance for the phone while mounted. The hollowed-out design maintains access to all iPhone buttons, ports, the radar system, the ultra-wide lens, and wireless charging so you do not need to remove the phone for basic operation.

For underwater shooting or high-performance cooling scenarios, you can mount the phone directly into the cage without the case. In that configuration, use the included TPU soft bumper alongside the cage to preserve fit and basic protection.

Quick lock and handling

The cage uses a quick lock mechanism that enables convenient and secure phone mounting and dismounting. It is designed to prevent accidental unlocking and phone ejection, helping to keep the iPhone stable during movement and real-world shoots.
