SmallRig 5543 Mobile Video Cage for iPhone 17 Pro Max Flagship Edition
In addition to providing daily protection for the phone, the case comes standard with a T-mount backplate and a 17mm threaded lens backplate for external lens mounting. The T-mount backplate can be replaced with a 67mm magnetic filter adapter (sold separately) for enhanced optical output.
The phone can be mounted into the cage with its case on.
The cage features multiple 1/4"-20 anti-twist threaded holes and cold shoe mounts to expand with accessories like handles, tripods, microphones, and lights. Classic quick release interfaces allow for efficient handheld or tripod setups.
Side-mounted strap holes are compatible with professional wrist and shoulder straps under 2mm in diameter, keeping your hands free between shots.
The hollowed-out design maintains access to all iPhone buttons, ports, radar system, ultra-wide lens, and wireless charging.
The quick lock mechanism allows convenient, secure phone mounting / dismounting and prevents accidental unlocking and phone ejection.
The all-metal construction provides comprehensive protection, shock absorption, and scratch resistance.
For underwater shooting or high-performance cooling scenarios, the phone can be used without the case by mounting it directly into the cage alongside the TPU soft bumper.
