Zhiyun Smooth 4 vs DJI Osmo Mobile 2: Best Smartphone Gimbal 2018

content: Ultimate Gimbal Showdown: Smooth 4 vs Osmo Mobile 2

Searching for the best smartphone stabilizer in 2018? After extensive hands-on testing with both the Zhiyun Smooth 4 and DJI Osmo Mobile 2, we've identified critical differences that impact real-world filmmaking. These similarly priced gimbals ($139 vs $129) deliver professional stabilization previously found only in high-end gear, but their approaches diverge significantly where it matters most.

Core takeaway: Both units eliminate shaky footage equally well across iPhone and Android devices. You won't distinguish stabilization quality in final footage. The decisive factors lie in control schemes, build quality, and specialized features that match different creator workflows.

Build Quality and Physical Design

The Smooth 4 feels notably more premium despite both using plastic construction. At 547g versus Osmo's 485g, the extra weight contributes to a sturdier feel without becoming cumbersome. Zhiyun includes a detachable mini tripod - a practical addition for tabletop shots that DJI omits.

Both accommodate phones from compact models to iPhone 8 Plus/Nokia 8 sizes. Battery life favors DJI slightly (15 hours vs Zhiyun's 12), though both exceed typical shooting sessions. Crucially, the Smooth 4 introduces a sleep mode - fold the arm to pause operation without full shutdown. This feature proves invaluable during on-location filming breaks when every second counts.

Control Systems and Shooting Modes

Here's where these gimbals reveal fundamentally different philosophies:

Zhiyun Smooth 4

Dedicated trigger system: Back-mounted trigger enables tilt-lock functionality. Press to tilt; release to lock position instantly
Physical mode buttons: Direct access to pan-follow, lock, and portrait modes
Focus/zoom wheel: First-in-class mechanical wheel (though practical value is debated)
No joystick: Relies entirely on button-based control

DJI Osmo Mobile 2

Front joystick: Allows manual camera positioning
Minimalist buttons: Single mode/power button with record trigger
No tilt lock: Limited to full lock or full pan-follow modes
Missing rear trigger: Omits a key control from the original Osmo Mobile

Our testing revealed the Smooth 4's trigger-based tilt control fundamentally changes shot flexibility. You can maintain pan movement while locking vertical tilt - impossible on the Osmo Mobile 2. This proves essential when filming subjects moving across uneven terrain.

App Experience and Smart Features

Both require proprietary apps to unlock advanced functions like timelapse and object tracking. Unfortunately, both apps demonstrated instability during testing:

DJI Mimo: Requires account creation but delivers superior object tracking. Once locked, it reliably follows subjects across complex environments
Zhiyun Play: Promised Android improvements are pending. Face tracking consistently failed during our tests, with the camera frequently losing subjects
Critical recommendation: For non-specialty shooting, use FiLMiC Pro instead. You'll maintain stabilization while gaining professional manual controls without app crashes

The zoom/focus wheel on Smooth 4 presents a solution searching for a problem. Smartphone lenses lack optical zoom capability, making digital zoom undesirable for quality-focused creators. Focus pulling similarly lacks practical application due to smartphones' deep depth of field.

Verdict: Which Gimbal Wins?

Choose Zhiyun Smooth 4 if:

You prioritize tactile control and shooting flexibility
Need tilt-lock capability for dynamic shots
Value physical buttons over touchscreen dependence
Appreciate premium build and included tripod

Choose DJI Osmo Mobile 2 if:

Object tracking is non-negotiable for your workflow
Prefer joystick camera positioning
Require maximum battery longevity

Final assessment: For most creators, the Smooth 4's superior control scheme and build quality justify the $10 premium. Its tilt-lock trigger and mode buttons provide tangible advantages during active shooting. While DJI's object tracking excels, that single advantage doesn't outweigh the Smooth 4's ergonomic benefits for general use.
