If you haven't heard the news yet, Moment released the SuperCage, the first pro-level mobile rig designed for all-day shooting on your phone.
Moment's engineering team has been hard at work perfecting the ultimate mobile rig. As a company that lives and breathes iPhone cinema gear, creating a metal cage to mount all your accessories was the next logical step. It's built to elevate your camera phone game, letting you shoot hours of footage while staying light enough to keep up with your travels.

And now, it's finally here.

I had an absolute blast trying it out. As a filmmaker used to building rigs for big-budget productions and small social campaigns, I obviously had to have a field day with it.

If you're a visual learner, check out the YouTube video at the bottom of the page. But for now, let's chat about my favorite SuperCage features and how I rigged up this bad boy for mobile filmmaking.

What Is the Moment SuperCage?

The SuperCage takes everything I loved about Moment's original Filmmaker Cage and cranks it up a notch. It's basically the "pro" version, packed with even more features, plus an integrated plug-in hub that makes everything run smoother.

Open Rail System

One of my favorite things about the SuperCage is its openness and versatility. You're not locked into a rigid system here. The open rail profile, with NATO compatibility on the sides and top and Arca on the base, means I can still use all my favorite accessories, grips, and tripods. It's got plenty of extra mounting points, including 4 cold-shoe mounts and a ton of 1/4" -20 threads, perfect for adding anything from lights to mics.

Integrated USB-C Hub

One of the biggest challenges with mobile filmmaking is managing all the accessories. Typically, you'd be stuck hunting for a USB-C hub for laptops —big, bulky, and not optimized for mobile setups. But Moment solved that by building a high-performance USB-C hub directly into the SuperCage. It's built specifically for your phone, so everything just works how it should. I can easily connect my pro-level gear and even record Apple ProRes without worrying about charging or data transfer issues.

Industrial Phone Clamp

The phone clamp on the SuperCage is a beast. It's industrial-grade, made from lightweight aluminum with a crazy strong spring that grips my phone tight. So, there's no need to worry about your phone slipping mid-shoot. The contoured rubber pads keep everything secure without scratching up my phone or case, and the anti-twist mount ensures everything stays right where I want it. Plus, the adjustable slide means I can get the lens exactly where I need it for different shots.

Multi-Directional Shooting

Versatility is key with the SuperCage and even more important for how I shoot my videos. Whether I'm shooting vertical for social media or switching to landscape for everything else, this rig handles it perfectly. I've used it handheld for those run-and-gun moments, mounted it on a tripod for stable shots, and even thrown it on a gimbal for smoother action scenes. The ability to configure it with ports facing toward or away from me also gives me complete control over my screen setup, which is a huge bonus when I'm trying to keep my rig clean and functional.

What I Love About It

The power hub and SD card sections are enormous for beginners and pro filmmakers. I always tell people to start with the phone when starting off their filmmaking journey because the phone is the simplest (and most feint) way to teach you all of the essential elements to Crafti a good film: lighting, movements, simple editing hacks, and basic settings that can be implements using the Moment Pro Camera App ( no cage necessary). To level up a phone, you need the cage to amplify footage on a cinematography level and for storage space while using the SD card slots.

On a hybrid level, this cage is perfect for social campaigns or brands that require timecodes or audio transmissions — all of the normal toggles I would see from a regular camera, now on the phone (plus amplified storage). It's the best b-cam!

How To Rig the SuperCage

One of the best parts of any camera gear is rigging it up — adding all the accessories to make it feel like a proper filmmaking setup, similar to an X-H2s or Sony FX3. I have a ton of accessories at my fingertips, so there are likely a ton more combinations to try in the future. But for now, here's the recipe I typically go for:

Step 1: Adding the Handle

First things first, I attached a wooden handle to the NATO rail. I love this handle—it’s got a solid grip and makes handheld shooting feel more natural. To get it on, start from the back, rock it forward, adjust, and lock it down. Easy.

Step 2: Mounting the Monitor

Next up, the monitor. I’m using a lightweight, affordable monitor mounted at the front to keep the rig balanced and avoid any unnecessary bulk. Having a monitor connected is a game changer compared to staring at the small LCD on the phone. It really elevates the shooting experience and makes it feel like a more professional setup.

Step 3: Securing the Phone

Now, let’s get the phone locked into place. The key piece is the USB-C cable connecting the phone to the cage for power. The SuperCage has handy notches along the horizontal edges for cable management, which is great for keeping things tidy. I’m a fan of using Wooden Camera’s cable ties for a clean, snag-free setup. There’s nothing worse than snagging a cable mid-shoot.

Step 4: Monitoring Audio

For audio, I always rely on the DJI transmitter system. Sure, the SuperCage has plenty of cable management options, but I love the simplicity of going wireless. It keeps everything cleaner and less cluttered. I paired it with my go-to mic — the Sennheiser MKE 40. It’s perfect for mobile setups, and since audio is often overlooked in filmmaking, this is one area I never skimp on.

Step 5: Connecting Additional Accessories

I used the cheese plate on the bottom of the rig for even more accessory mounting. You can attach just about anything. I ran additional cables through the plate and hooked up the HDMI port so all my gear worked seamlessly as one system.

Step 6: Expanding Storage

For storage, I popped in a 1TB SD card from Angelbird. This gave me over 200 minutes of ProRes recording on my iPhone, which is insane for mobile filming. No more worrying about running out of space mid-shoot.

Step 7: Adding the Lens

Finally, I attached Moment’s Wide 18mm mobile lens. This lens is my go-to for adding that extra scene to the frame, especially when vlogging or filming out in the field. It’s wide enough to capture everything but not so wide that it feels distorted.

And the best part? The SuperCage is light enough that even with all these accessories, it doesn’t become a burden to carry around. I can shoot all day without my shoulders feeling it.
