Hands-On First Impressions of Xiaomi Mijia Mi Sphere 360 Camera: a Theta hunter?

I just received my order of the Xiaomi Mijia Mi Sphere 360 Camera from GearBest!  Here are my first impressions.

Part 2 of my first impressions (with unboxing, sample 360 video, and image stabilization preview) is here.
Here is a comparison / review of the Xiaomi versus the 2017 Gear 360.  It also has a guide for the viewing and exporting from the Xiaomi.

A few weeks ago, Xiaomi Mijia announced the Mi Sphere camera, a fully spherical 360 camera.  Here are the key specifications:
– two 190-degree lenses, fully spherical field of view
– f/2.0 aperture
– photo resolution: 7K (6912 x 3456)
– video resolution: 3.5K (3456 x 1728 @ 30fps)
– IP67 water resistance
– 6-axis image stabilization
– removable Micro SD memory
– compatible with iOS and Android

The box was surprisingly small.  It included:
– the Mi Camera
– a sleek carrying pouch (seems made from a water resistant material, but with a fabric interior lining)
– a mini tripod / handle
– micro USB cable
– instructions and warranty card.

The Mi Sphere feels sleek and very well made.  The edges of the Mi Sphere are metal, which not only contributes to a solid feel but I believe also helps dissipate heat.  The matte black finish reminded me a lot of the Ricoh Theta, but with a unique credit card-like shape.

The Mi Sphere Camera is very slim.  It seems slightly slimmer than the body of the Ricoh Theta, although the distance between the lenses is almost the same.

The buttons on the Mi Sphere feel very good and have a positive feel, not at all mushy.  The controls are elegant and intuitive.  There’s a power button that also doubles as a mode switching button, a wireless button, and a shutter button.  There are hidden LED indicator lights that are invisible when they are not lit (another similarity with the Theta S).  My only complaint is that there doesn’t seem to be a self-timer mode without the app.

One difference from the Theta is that the Mi Sphere has a removable Micro SD card.  There’s a Micro USB port but no micro HDMI port.
There is a standard 1/4-20 tripod insert at the bottom, made of metal.  The included mini tripod has a similar design to the tripod that came with the original Samsung Gear 360.  It’s made of metal, is spring loaded, and has rubber tips for friction.
One thing that is a little unusual is that the manual included in the package is all in Chinese.  I am hoping that when it is eventually sold in the US, that there will be an English manual for it.
The Mi Sphere has an app for both iOS and Android, which you can find by scanning a QR code in the manual.  The iOS app is here.  The Android app is here.  Both apps were in English on my phones.  The iOS and Android apps look identical.
Connecting the camera to the app was relatively simple, and there’s a graphical tutorial in the app.  You just turn on the Wi-Fi on the camera, connect to it with your phone, then tap on the camera icon on the app to connect.  One comment is that my phone was warning me that internet access isn’t available with this wi-fi “network.”

The interface is simple.  At the bottom, there’s a gallery button, shutter button, a toggle between photo and video.  Above that, you’ll see self-timer (for photo mode) or a short video mode and time-lapse mode (for video).

On the upper right corner are the settings.  Yes it has manual exposure, shutter priority, and ISO priority!  Moreover, the shutter speed can be as slow as 32 seconds — enough for night sky photos!  ISO is as low as 50, which can let us use long exposure shots in brighter conditions!

One unusual option is “recording cycle.”  I don’t know exactly what it is, but it seems to be the image stabilization.


I took a few test shots. Here is a sample photo:

Here are my observations:
+ Sharpness is very good, with plenty of detail, although part of the sharpness could be because the photos seem sharpened by the internal JPG processing.
+ Unlike the Theta, the lens appears to be sharp edge to edge (the Theta softens toward the stitch line).
+ exposure is spot-on
+ Colors appear natural, with accurate hues.
+ very good contrast level, yet shadows do not appear too dark. Very nice balance of highlights and shadows in my opinion.
+ excellent flare resistance
+/o The stitching looks pretty good although it’s not perfect, and there is a little bit of smearing and doubling at the stitch line.
o dynamic range appears similar to the Theta, with some noise / grain in the shadows.  Not sure yet re highlight detail but so far I haven’t seen anything impressive.
– It has chromatic aberration like the Ricoh Theta.
– vertical correction seems to be inaccurate.

In short, my initial impression is that the Mi Sphere 360 has some of the best-looking photos for a consumer 360 camera.  Combined with exposure controls that are as good as those of the Theta, this could be an excellent 360 photo camera.

For videos, I haven’t had the chance to upload them yet but on the phone, they look darn good.  I’ll post them in a while.

Photos and videos are not stitched in the camera.  However, when I review them on the app, I can view them stitched without having to wait.  It’s only when I download them from the camera to the app that I do have to wait a while because it seems to be stitching and downloading at the same time.

The app has a few sharing options.  Here are the sharing options for photos:

Here are the sharing options for videos:

It’s strange not to see YouTube as an option for sharing to video.  Oh well.

Anyway, like I said these are just my first impressions.  I’ll post some sample videos later.

Part 2 of my first impressions (with unboxing, sample 360 video, and image stabilization preview) is here.
Here is a comparison / review of the Xiaomi versus the 2017 Gear 360.  It also has a guide for the viewing and exporting from the Xiaomi.

If you have any questions, please leave them in the comments and I’ll do my best to answer.  And of course, I will include the Mi Sphere in my mega comparison (with at least 12 cameras).  The Mi Sphere is available from GearBest.

  • Hi Micheal, this seems the one for High Res. Point and Shoot 360 photo’s. (instead of the new Samsung Gear360 with all of it’s flaws within IOS). You haven’t mentioned HDR toning or imaging.
    Is it because it’s not available on the camera (or in the app)? Do you know what specs there are reguired if you want to work with a Mac? Thanks again for this nice review. A product I wasn’t expecting to be that exiting. Do you agree..? Grtz, Maxim – The Netherlands

    • Hi Maxim. I don’t see an HDR mode in the app.

      I don’t know of any desktop software for either PC or Mac.

      I agree – I wasn’t excited about this product when it was announced but now that I’ve shot with it, I’m impressed! They do need to improve the bugs in the app though!

      Best regards,

  • Hi Mic,
    Nice first look. The quality of the photos looks much better than the Theta on the small image above. What does it look when blown up?
    Another question, can this camera live stream?

    • Hi Garry. The embedded photo on roundme is full resolution. you can click on the upper right corner for the menu and look for the second option ‘fullscreen’.

      It appears it cannot live stream.

      Thanks and let me know if you have other qs…

      Best regards,

  • This looks great! Thanks for the review. Does it have an intervalometer? If not does it work with the Google Street View app? Also does it have Open Spherical Camera API?

    • Sorry i don’t see an intervalometer. There is a time lapse feature but you don’t get the individual shots. I doesn’t connect with the current version of the street view app. I don’t know if it has open spherical camera api (the fact that it doesn’t connect to GSV tells me that it probably doesn’t).

      Best regards,

  • so my question is

    nikon key mission 360 450 euro
    theta s 299 euro
    xiaomi mijia 249 euro

    i ‘ need a 360camera for picture nt for video
    i’m google trusted photographer and i work with nikon d7200 + sigma 8mm

  • I wish it had bracketed capture and ability to export the individual images for manual stitching and HDR processing.
    The blown highlights that plague every other such camera are here too.
    On the plus side, price and manual settings. Sharpening needs to be toned down, it’s too much.

    • Hi Adam. Sorry, I don’t know about whether you can add Python code to the Mi Sphere.

      Best regards,

  • Hi, how did you stitch videos above? Using “mi sphere” app? Or you dowloaded them via usb and used another software for stitching?
    Becouse when you want to share the video in Mi Sphere app, there is only option to share a link. How to upload 360 photo or video to facebook directly? :/ Thank You

  • Hello Michael

    Can you preset a timer (count down timer) on this camera? So i dont need to connect it to the phone app whenever i take a selfie or sth.

    thank you

    • Hi Ray. Right now there seems to be no in-camera way to use self-timer. It has about a 1 second delay from the time you press the shutter until the time you take a shot – that’s all… Otherwise, you’ll need the app to use the self-timer.

      Best regards,
