This is the English edition of a video from my Japanese YouTube channel, iestaLife. I test gadgets and camera gear at home in Japan, so product links go to Amazon Japan.
Quick take
I bought two cheap camera bars: a long UTEBIT bar that holds up to four devices, and a short two-device plate. The four-device bar is a simple way to mount action cameras side by side so they move with exactly the same shake, which makes stabilization and image-quality comparisons fair. The two-device plate let me put my camera and microphone on a single tripod. Both cost roughly 1,000 yen each at the time of recording.

What I tested
- UTEBIT camera shoe bracket, about 30 cm, up to four devices
- A short two-device camera plate (brand not visible)
- On the long bar: DJI Osmo Action 4, a 360-degree camera and an iPhone Pro Max
- On the short plate: a ball head with my main camera, plus a shotgun mic, on one tripod
What I found
Four-device bar for comparisons. With all cameras on one bar, they move together on the same bar as you walk, so differences in stabilization and image quality are easy to see. Hold the bar near the middle; holding one end makes each camera move differently.

Two catches. Holding the bar with both hands is steadier than normal one-handed walking, so footage may look a bit better than real-world use. And although it is rated for four devices, a wide phone like the iPhone Pro Max takes up space; with one on the bar, three devices was about the limit.
Two-device plate for a tidier tripod. In my recording room, the camera sat off-center and the mic was clamped to the sofa in an awkward spot. I put the short plate on the tripod with the camera and ball head on one end and the mic on the other. The plate felt sturdy with my setup. The background framing did not change as much as I hoped, but having the camera and mic on one tripod was handy.

Comparison
| Four-device bar | Two-device plate | |
|---|---|---|
| Capacity | Up to 4 | 2 |
| My use | Side-by-side action camera tests | Camera + mic on one tripod |
| Watch out for | Wide phones reduce it to about 3 devices | Framing may need some adjusting |
Who it’s for
- Anyone comparing action cameras or phones under the same conditions
- Anyone with one tripod who wants a camera plus a mic on it
- Not ideal if you want test footage that exactly matches casual one-handed walking
Watch the video
The video is in Japanese, but the setup is easy to follow. Useful moments: around 1:20 for the cameras on the long bar, and 3:50 for the camera-and-mic tripod setup.
Limitations
This is a short first-use video, not a long-term test. I did not measure load capacity; I only used my own camera setup. The short plate had no visible brand, so I cannot point to the exact listing.
