SmallRig 5543 Mobile Video Cage for iPhone 17 Pro Max Flagship Edition

SmallRig 5543 Mobile Video Cage for iPhone 17 Pro Max — Professional expansion solution for video, streaming, and short films

This kit delivers a professional expansion solution designed specifically for the iPhone 17 Pro Max. It supports professional-level video recording, live streaming, and short film production while also serving as daily protection for your phone.

Key features and modular lens options

The included phone case comes standard with a T-mount backplate and a 17mm threaded lens backplate for external lens mounting. In addition, the T-mount backplate can be replaced with a 67mm magnetic filter adapter (sold separately) to enhance optical output. These modular options let you adapt the cage to different optical setups.

Mounting, expansion and quick setup

You can mount the iPhone into the cage while it remains in its case, which simplifies switching between handheld and rigged setups. The cage includes multiple 1/4"-20 anti-twist threaded holes and cold shoe mounts. Therefore, you can expand the setup with accessories such as handles, tripods, microphones, and lights. Classic quick release interfaces allow efficient transitions between handheld use and tripod setups.

Straps, access and ergonomics

For hands-free convenience between shots, the cage has side-mounted strap holes that accept professional wrist and shoulder straps under 2mm in diameter. Meanwhile, the hollowed-out design maintains clear access to all iPhone buttons and ports, the radar system, the ultra-wide lens, and wireless charging. This preserves core phone functions while it is mounted in the cage.

Security, protection and alternative mounting

The quick lock mechanism ensures convenient and secure phone mounting and dismounting. It also prevents accidental unlocking and phone ejection during use. The cage’s all-metal construction provides comprehensive protection, shock absorption, and scratch resistance for the device.

For specific shooting scenarios, such as underwater use or high-performance cooling, you can mount the phone directly into the cage without the case and use it together with the supplied TPU soft bumper.
