Ulanzi ST-29 Phone & Tablet Tripod Mount

The Ulanzi ST-29 Tripod Mount for Smartphone and Tablet is a highly versatile, budget-friendly 2-in-1 clamping ecosystem engineered to bridge the gap between mobile phone and tablet production setups. Moving past standard phone-only clips, the ST-29 features an ultra-wide, multi-stage telescoping jaw that expands from 6.7 cm up to 22.5 cm (2.63 to 8.85 inches). This massive range allows it to secure a compact smartphone for quick on-the-go tracking shots or hold a massive 12.9″ iPad Pro for desktop live-streaming, video conferencing, or teleprompter monitoring.

Molded from high-impact ABS resin, the ST-29 balances a featherweight profile of just 64 grams with smart structural features. It includes dual universal 1/4″-20 threaded mounting options and a dedicated top-facing cold shoe slot to quickly build an external rig. It also features an open pass-through access cutout at the base of the frame, allowing you to run a USB-C or Lightning cable to your device for continuous, uninterrupted charging while streaming or shooting.

Ulanzi ST-29 Key Features & Product Overview

• Massive 2-in-1 Extension Range: Ditch separate mounts for your different devices. The heavy-duty telescoping mechanism extends wide enough to shift seamlessly from a small mobile phone to a full-sized tablet.
• Telescopic Push-Button Adjustment: Lock in your device securely with minimal effort. The mount utilizes a quick-release telescopic button interface that lets you slide the arm open smoothly and clamp it down precisely onto your hardware.
• Dual 1/4″-20 Thread Configuration: Mount your gear exactly how you need it. With universal threaded ports positioned on both the bottom and back of the casing, you can secure the bracket flush against a traditional tripod head, a selfie stick, or an overhead desktop armature.
• Top-Facing Cold Shoe Extension: Build a clean micro-production station. The top edge houses an integrated cold shoe track, letting you mount compact wireless microphone receivers or portable LED fill lights right above your screen.
• Anti-Slip Protective Grid Lining: Keep your expensive screens and edges safe from scuffs. The interior clamping jaws are layered with deep, protective silicone grooves, and the backplate features a high-density sponge pad to prevent your device from sliding around.

Ulanzi ST-29 Pros & Cons

Pros

• True Universal Versatility: It serves as a one-stop tool for hybrid workflows, instantly adapting to support an iPhone, an Android flagship, or an iPad Pro without needing separate gear.
• Featherweight Portability: Weighing only 64g and collapsing down to just 3.2 inches, it can easily slide into any pocket or tech pouch without adding bulk.
• Continuous Charging Slot: The clever base cut-out solves a common problem for live-streamers, keeping power cables neatly routed so your device doesn’t die mid-broadcast.
• Budget-Friendly Efficiency: Offers an affordable way to add professional tablet mounting capabilities to your rig without the premium price tag of all-metal cage setups.

Cons

• ABS Plastic Structural Body: While highly durable for day-to-day production, the lightweight ABS resin frame doesn’t offer the extreme, heavy-duty impact resistance of CNC aluminum mounts like the Ulanzi ST-10.
• Landscape-Only Tablet Framing: While smartphones can easily be flipped to vertical mode within the clamp, large tablets must be mounted horizontally (though your tripod head can be tilted 90° to compensate).

Ulanzi ST-29 Suitable Application Areas

• Zoom Conferences & Virtual Classrooms: Secure your tablet perfectly at eye level. Mount the ST-29 onto any compact tabletop tripod, insert your iPad, slide a wireless microphone receiver onto the top cold shoe, and run a charging line for a crystal-clear, day-long video call setup.
• On-Camera Teleprompter Monitoring: Use your tablet as an on-set teleprompter or external director’s monitor. Attach the bracket to a stand behind or beside your main mirrorless camera rig, allowing presenters to easily read scripts or review shots.
• Cooking, Crafting, & Overhead Streaming: Mount the adapter to an articulating arm using the rear 1/4″-20 threaded hole. Position your smartphone or tablet facing completely flat downward over a counter space to film hands-free tutorials or top-down crafting clips.

Ulanzi ST-29 Verdict

The Ulanzi ST-29 Tripod Mount for Smartphone and Tablet is a smart, hyper-portable, and incredibly cost-effective tool that brings great flexibility to content creators on the move. While high-impact outdoor filmmakers might prefer heavy all-metal clamps, the ST-29 shines in mobile vlogging, desktop streaming, and multi-device studio setups. By pairing a wide-stretching 2-in-1 telescoping jaw with dual mounting threads, a built-in cold shoe, and a continuous charging slot, Ulanzi offers an essential accessory for anyone looking to maximize their mobile or tablet production setup.
