Feiyu Tech GM-G4-S 3-Axis Gimbal for Sony Action Camera – Smooth Stabilization

The Feiyu Tech GM-G4-S 3-Axis Gimbal delivers buttery-smooth stabilization for Sony action cameras, eliminating shaky footage in any environment. Lightweight, rugged, and easy to use, it’s the ultimate tool for adventurers and content creators demanding professional-grade video without the bulk.

Key Takeaways

• Superior stabilization: Achieve smooth, shake-free footage with advanced 3-axis motor control.
• Perfect Sony compatibility: Designed exclusively for Sony action cameras like the RX0 and AS series.
• Quick setup: Tool-free mounting lets you start filming in seconds with no hassle.
• All-day power: Extended battery life supports long shoots without frequent recharging.
• Smart controls: Intuitive joystick and buttons for precise, real-time adjustments on the fly.
• Lightweight & portable: Compact design makes it easy to carry and travel-friendly.

Why Smooth Footage Matters for Action Cam Enthusiasts

Let’s be honest: nothing ruins an epic mountain biking clip or a snorkeling adventure faster than shaky, nauseating footage. You’ve got the Sony action cam—maybe the RX0 II or the ZV-1—but the raw video feels like it was shot on a rollercoaster. That’s where the Feiyu Tech GM-G4-S 3-Axis Gimbal for Sony Action Camera steps in. It’s not just another accessory; it’s your secret weapon for turning bumpy, handheld chaos into buttery-smooth cinematic magic.

I remember filming a sunset hike last year. The trail was rocky, my hands were cold, and my footage? A blurry mess. I spent hours editing, trying to stabilize it in post, only to end up with a choppy, over-processed result. If I’d had the GM-G4-S back then, I could’ve saved time, energy, and my sanity. This gimbal isn’t about flashy specs—it’s about solving real problems: shaky hands, unpredictable terrain, and the frustration of losing your best shots to poor stabilization.

First Impressions: Unboxing and Setup

What’s in the Box?

When you open the Feiyu Tech GM-G4-S package, you’re greeted with a compact, travel-friendly case. Inside, you’ll find:

• The 3-axis gimbal (folded for storage)

<

• Quick-release plate for Sony action cams
• USB-C charging cable
• User manual (in multiple languages)
• Spare screws and a hex key

No fluff, no unnecessary extras. The design feels minimalist but intentional—everything has a purpose. The gimbal itself is lightweight (about 290g) and folds down to fit in a backpack side pocket. For travelers or vloggers on the move, this portability is a game-changer.

Attaching Your Sony Action Camera

Setting up the GM-G4-S is surprisingly simple, even if you’re a gimbal newbie. Here’s how it works:

• Step 1: Slide the quick-release plate into your Sony camera’s tripod mount. (It’s compatible with most Sony action cams, including the RX0 II, FDR-X3000, and ZV-1.)
• Step 2: Tighten the screw with the included hex key. No wobbling—just a secure, tool-free attachment.
• Step 3: Power on the gimbal and let it auto-balance. The motors adjust in seconds, and you’re ready to roll.

Pro tip: Always balance your camera before turning on the gimbal. If the lens is front-heavy, adjust the plate forward until the camera stays level when you let go. This prevents motor strain and ensures smoother stabilization. If you’re comparing Feiyu models, the Feiyu G5GS offers similar Sony-specific performance with slightly different ergonomics.

Performance Deep Dive: How Well Does It Stabilize?

Real-World Testing: Hiking, Biking, and Running

I took the GM-G4-S on a 3-day trip to test its limits. First up: a rocky mountain trail. With my Sony RX0 II mounted, the gimbal absorbed every bump and jolt. Even when I tripped (yes, it happens), the footage stayed eerily stable. The 3-axis system—pan, tilt, and roll—worked in harmony to counteract sudden movements.

Next, I tried it while biking downhill at 25 mph. The gimbal’s Sport Mode (activated by double-tapping the mode button) locked the horizon and minimized high-frequency shakes. The result? A smooth, immersive POV shot that made me feel like I was back on the trail.

For running, the gimbal handled vertical bounce better than I expected. While it can’t eliminate 100% of footfall shake (no gimbal can), it reduced it enough that my footage looked professional—not like a home video.

Low-Light and Slow-Motion Scenarios

Action cams shine in low light, but shaky footage can ruin long-exposure shots. I tested the GM-G4-S during a night hike using the Sony ZV-1’s 120fps slow-motion mode. The gimbal’s motors stayed whisper-quiet, with no vibration bleed into the footage. Even when I panned slowly to track a firefly, the motion was fluid and cinematic.

One limitation: if you’re shooting in extremely low light (e.g., a moonless forest), the gimbal’s motors may struggle with micro-shakes. For these scenarios, I’d recommend pairing it with a small LED light to help the camera stabilize faster.

Battery Life and Charging

The GM-G4-S uses a 2500mAh battery, which Feiyu claims lasts 6-8 hours. In my tests, it averaged 7 hours with moderate use (mix of walking, panning, and brief sprints). Charging via USB-C takes about 2.5 hours—perfect for a mid-day recharge during a long shoot.

Pro tip: Carry a power bank. If you’re filming all day, plug in the gimbal during breaks. The USB-C port doubles as a power pass-through, so you can charge your camera too.

Design and Build Quality: Built for Adventure

Durability: Can It Handle the Elements?

Feiyu Tech built the GM-G4-S with outdoor use in mind. The body is made of magnesium alloy and polycarbonate—lightweight but tough. I accidentally dropped it into a stream (oops), and after a quick rinse and dry, it worked flawlessly. No corrosion, no motor issues.

The motors are sealed against dust and moisture, which is critical for hikers, surfers, or anyone filming in humid environments. Just don’t submerge it—this isn’t a waterproof gimbal, only splash-resistant. For truly wet environments, consider the Feiyu SPG water-resistant gimbal, designed for tougher conditions.

Ergonomics and Controls

The handle is contoured for a secure grip, with rubberized padding to prevent slippage. The buttons are intuitive:

• Mode button: Cycle between Pan Follow, Lock, and Sport modes.
• Joystick: Adjust camera angle manually (great for framing shots).
• Shutter button: Start/stop recording on your Sony camera.

One quirk: the joystick is a bit stiff out of the box. After a week of use, it loosened up and became more responsive. If you’re used to touchscreen controls, this might feel old-school, but it’s reliable—no accidental taps while filming.

Portability and Travel Friendliness

The GM-G4-S folds flat, making it easy to pack. I fit it into a 10L backpack alongside my camera, snacks, and a water bottle. For international travelers: it’s airline-approved (no lithium battery restrictions).

One downside: the quick-release plate adds 20g to your camera. If you’re a minimalist, you’ll need to decide whether the stability trade-off is worth it.

Advanced Features: Beyond Basic Stabilization

App Integration and Customization

The Feiyu Tech app (iOS/Android) unlocks advanced features:

• Motor strength adjustment: Fine-tune stabilization for heavy cameras or fast movements.
• Auto-rotation: Program the gimbal to rotate 180° for selfie-mode transitions.
• Timelapse presets: Set motion paths for dynamic timelapses (e.g., sunrise over a valley).

I used the app to create a “dolly zoom” effect by syncing the gimbal’s pan with my camera’s zoom. It took a few tries, but the result was Hollywood-level cool.

Note: The app occasionally disconnects if you’re far from the gimbal. Keep your phone within 10 meters for reliable control.

Multi-Camera Support and Accessories

The GM-G4-S isn’t just for action cams. With an optional adapter, it can hold:

• Compact mirrorless cameras (e.g., Sony a7C)
• Smartphones (via a clamp accessory)
• 360-degree cameras (e.g., Insta360 ONE X2)

I tested it with my iPhone 14 Pro using the FeiyuTech phone clamp. While the stabilization was excellent, the gimbal struggled with the phone’s weight distribution. Stick to lighter setups for best results.

Creative Shooting Modes

The gimbal’s POV Mode is a hidden gem. It mimics the motion of your hand, adding subtle shake for a “first-person” feel. Perfect for vlogs or immersive travel videos. To activate it, hold the mode button for 3 seconds.

Another favorite: Portrait Mode (single-tap the joystick). It rotates the camera 90° for vertical shots, ideal for Instagram Reels or TikTok.

Comparing the GM-G4-S to Competitors

How It Stacks Up: DJI, Zhiyun, and Feiyu

The GM-G4-S competes with gimbals like the DJI Osmo Pocket 3 and Zhiyun Crane-M2S. Here’s how it compares:

Feature	Feiyu GM-G4-S	DJI Osmo Pocket 3	Zhiyun Crane-M2S
Weight	290g	179g	570g
Battery Life	7 hours	166 mins	7 hours
Sony Action Cam Support	Yes (native)	No (requires adapter)	Yes (with adapter)
Price	$199	$519	$299
App Features	Basic customization	Advanced AI tracking	Mid-tier presets

The GM-G4-S wins on price and Sony compatibility. It’s half the cost of the DJI Osmo Pocket 3 and doesn’t require clunky adapters. However, the DJI offers better auto-tracking, and the Zhiyun has more payload capacity.

Who Should (and Shouldn’t) Buy It?

Buy the GM-G4-S if you:

• Shoot with a Sony action cam and want plug-and-play stabilization.
• Prioritize portability over pro-level features.
• Need a budget-friendly gimbal under $200.

Skip it if you:

• Use a heavy mirrorless camera (e.g., Sony a7 IV).
• Require AI-powered subject tracking.
• Film underwater (it’s splash-resistant, not submersible).

Final Verdict: Is the GM-G4-S Worth It?

After weeks of testing, the Feiyu Tech GM-G4-S 3-Axis Gimbal for Sony Action Camera has earned a permanent spot in my gear bag. It’s not perfect—the app could be more intuitive, and the joystick takes getting used to—but it delivers where it counts: smooth stabilization, durable build, and Sony compatibility.

For action cam users, this gimbal is a no-brainer. It turns your Sony RX0 II or ZV-1 into a mini cinema rig. No more shaky clips, no more wasted shots. Just clean, professional footage that does your adventures justice. Whether you’re a vlogger, traveler, or weekend warrior, the GM-G4-S helps you share your story—without the nausea.

At $199, it’s a smart investment. You could spend more on a high-end gimbal, but you’d be paying for features you might never use. The GM-G4-S focuses on what matters: making your footage look amazing, no matter how rough the ride.
