Comparison review: Xiaomi Mi Sphere 360 camera vs. 2017 Samsung Gear 360

All the attention right now is on the 2017 Samsung Gear 360, but there’s a less known 360 camera that may actually be better, for about the same price — the Xiaomi Mi Sphere 360 camera.  In this post, I compare photos and videos from the two cameras, as well as describe the workflow for the Xiaomi to help you decide if the Xiaomi is better for your needs.

Here is a video comparing the two cameras:

PHOTOS
Here are sample photos from the Xiaomi, including a comparison photo with the 2017 Gear 360.

Here are my observations:
1.  The Xiaomi has much more detail.  This is not surprising because the Xiaomi’s photo resolution is significantly higher (6912 x 3456) compared to the Gear 360 (5472 x 2736).
2.  In shadow areas, the Xiaomi has an even bigger advantage.  The Xiaomi retains detail in shadow areas, whereas the Gear 360 has much less detail in the shadows.  The Gear 360 also has much more noticeable chroma noise in shadows.
3.  The Xiaomi has almost edge to edge sharpness, losing sharpness only very close to the stitch line.  The 2017 Gear 360 is noticably less sharp over a wider area near the stitch line.
4.  Both have good stitching, although the Xiaomi is prone to slight doubling, while the Gear 360 is prone to slight smearing.
5.  Both have purple fringing, although it’s much more noticeable with the Xiaomi.

Overall, I would say the Xiaomi has noticeably better photo quality than the 2017 Gear 360.  Furthermore, the Xiaomi has manual exposure control.  You can also use ISO priority by specifying the ISO and then leaving the shutter speed on Auto, or vice-versa to use shutter priority.  Finally, the Xiaomi’s shutter speed is as slow as 32 seconds, which should be sufficient for night sky photos.

VIDEOS
Now let’s compare videos.  Nominally, the 2017 Gear 360 has higher video resolution (4096 x 2048 @ 24fps) versus the Xiaomi which has a video of 3456 x 1728 @ 30 fps. However, as you’ll see specifications are no substitute for a real-world comparison.  Here are sample videos as part of a playlist so you can switch between them using the playlist menu, or with the chapter search buttons:

Observations:
1. Surprisingly, even though the Gear 360 has a higher nominal resolution, the Xiaomi has at least the same level of detail as the 2017 Gear 360, and it might even seem slightly sharper.

 

2.  For shadow areas, the Xiaomi has far more detail than the Gear 360, again notwithstanding the Gear 360’s higher nominal resolution.

3. The stitching for video looks smoother for both cameras, although the Gear 360 has some warping whenever something crosses the stitch line near the camera.

VIEWING AND SHARING ON XIAOMI
Viewing and sharing photos on the Xiaomi is straightforward.  Photos are unstitched in the memory card, then stitched in the app.  There’s an app for both iOS and Android.  There seems to be no desktop software.  When you view the photos in the app, the app seems to stitch them at the same time and put the stitched copy in your phone’s gallery.

As I mentioned in the video, sharing videos on the Xiaomi is buggy.  There are two methods I’ve found.

Option 1 (I used this for iOS):
1. Open the video.
2. On the bottom, tap on the 3 dots.
3. Tap on the option with the arrow pointing up.  This will export the video to your camera roll.
If the video is not exporting, see option 2.
4. Insert 360 metadata with the YouTube metadata injector or with VRFix.
5. Upload to your preferred sharing site.

Option 2 (Android only.  I use this on Android because when I try Option 1 on my Samsung S8, it doesn’t seem to export and gets stuck at 0%.  So this is my workaround):
1. Open the video
2. Click on edit
3. Save the file
4. Go to your phone’s DCIM\MadV360 directory.
5. Insert 360 metadata with the YouTube metadata injector or with VRFix or with a video editor such as Collect 360 or V360.
6. Upload to your preferred sharing site.

Re gyro stabilization, here’s how to view it and share it:
1.  Download the video to your phone.
2.  Exit to the gallery and re-load the video.  Tap on the three dots and you’ll see a new option that looks like an atomic symbol.  Toggle it on.  The video will now be stabilized.
3.  To share the stabilized video, tap on the upper right corner.  Select “Moments”.  Enter a title and description. Share it.  You’ll find the video listed in your profile.
4.  To view the shared video with stabilization, tap on it, then tap on the three dots and you’ll see a new option that looks like an atomic symbol.  Toggle it on.  The video will now be stabilized.

I really hope Xiaomi fixes the app because it is quite buggy for videos, and it’s the only major weakness for this otherwise excellent 360 camera.  Xiaomi Mi Sphere is available from GearBest here, which would support 360 Rumors at no additional cost to you.  Thank you very much!

  • If you don’t need the live streaming, consider buying the 2016 Gear 360. eBay Germany is flooded with these cameras now because Samsung is bundling them with their popular phones and many people don’t seem to be interested.

    This means you can easily get a shrink wrapped Gear 360 for less than 100€.

  • Hello,

    Thanks for taking so much time to show the difference between both cameras. I’m tempted by the Xiaomi but video quality is still very poor compared to what you can get from a solo camera. I read that compression in YouTube has a negative effect on this but also the software you use for the stitching. I was wondering if you can access raw (= untouched, not stitched) video and photo files from the camera and if yes, do you see the same loss in quality?
