Product Information
Full details
The Ulanzi ST-27 is a professional-grade, all-metal smartphone tripod adapter designed for content creators who need maximum stability and expansion options for mobile vlogging or live streaming. It is ideal for users who frequently switch between portrait and landscape orientations and require additional mounting points for lights and microphones. One caveat to note is that while the heavy-duty metal construction provides excellent durability, it is slightly heavier than basic plastic mounts, making it best suited for stationary tripod or gimbal setups rather than ultra-lightweight handheld travel.

Does it fit an iPhone 13 Pro Max with a thick case?

Is the mount made of plastic or metal?
The ST-27 is crafted from high-quality aluminum metal for maximum durability.
How many accessories can I attach at once?
You can use up to three cold shoe mounts (back and sides) and three 1/4" screw holes simultaneously.
Does it come with a tripod?
No, the ST-27 is a smartphone adapter mount; a tripod must be purchased separately.

Troubleshooting
Phone feels loose in the clamp
Ensure the clamping knob is fully tightened and that the silicone pads are free of dust or oils.
Cannot attach to my tripod
Verify if your tripod uses the Arca-Swiss standard; if not, use the 1/4" threaded hole at the bottom of the adapter to attach it normally.
Difficult to rotate the mount
Check if the rotation lock screw is over-tightened; loosen it slightly to allow for smooth 360-degree movement.
