SmallRig 5543 Overview

Designed for the iPhone 17 Pro Max, the Mobile Video Cage Flagship Edition from SmallRig is a professional expansion solution for videography, live streaming, and more. Built using metal, it provides shock absorption and scratch resistance. Included is a phone case, a TPU soft bumper, a T-mount lens backplate, and a 17mm lens backplate.

Your phone may be mounted in the cage with or without the case on. The cage features multiple 1/4"-20 anti-twist threaded holes and cold shoe mounts for attaching accessories that include handles, tripods, microphones, and lights. Furthermore, quick release interfaces allow for user-friendly handheld or tripod setups, while a quick-lock mechanism keeps your phone secure by preventing accidental unlocking and phone ejection. 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.

The T-mount lens backplate supports T-mount lenses and may be swapped out for a 17mm threaded backplate or a 67mm filter adapter, the latter of which is sold separately. A strap hole on the case lets users attach a wrist strap or other accessory to help prevent accidental drops and falls, while a hollowed-out design retains access to your phone's functions, including its buttons, ports, lenses, and charging interfaces.

NOTE: Avoid using third-party phone cases with this product, as incompatible cases may damage your phone.

SmallRig 5543 Reviews

Decent case, but has major build quality issues.

Kick stand gets loose after a few months and just flops around when closed. Lens module also gets loose with age and is hard to trust for any production work - I have to tape it down when using expensive filters on it.
