Xiaomi mi mix 3 front camera review

Conclusion

The last couple of years have been exciting for mobile photography, as manufacturers have developed multiple sensors and lenses for their rear cameras, and combined that hardware with advanced signal processing to maximize imaging possibilities. Xiaomi is one of the first to apply this approach to the front camera, and the benefits are clear, with the Mi MIX 3 delivering excellent results for flash and bokeh, thanks to the built-in selfie light and depth-sensing second sensor. Other attributes such as face exposure, color, and detail are also impressive, and thanks to generally good skin tone rendering, the Mi MIX 3 ranks high in our database of front camera image quality. There are things it can improve, of course, most notably the fact that both focus and depth of field are too limited. Denoising and dynamic range could be better as well, but given its many pluses, along with good results when shooting video, it’s clear that the Xiaomi Mi MIX 3 is a solid choice for the selfie enthusiast.


Photo Pros

  • Excellent bokeh with precise depth estimation
  • Well-controlled noise indoors and in low light
  • Nice texture-versus-noise compromise
  • Good flash exposures

Video Pros

  • Low noise in all lighting conditions
  • Nice color rendering when white balance is accurate
  • Well-preserved detail at 30cm distances
  • Effective stabilization system

Video scores explained

The Xiaomi Mi MIX 3 front camera achieves an improved score of 85 points for video, making it a good device for selfie videographers. We calculate the overall video score using the following video sub-scores: Exposure (62), Color (83), Focus (61), Texture (70), Noise (79), Artifacts (87), and Stabilization (76).

Shooting video, the Mi MIX 3 exposes targets accurately in all lighting conditions, achieving good brightness on faces except in extreme low-light environments of 5 and 1 lux. Dynamic range in videos is again limited, however, and although faces are often accurately exposed, expect to see some highlight clipping on faces and overexposed backgrounds when capturing images in tricky high-contrast conditions. We also observed some exposure instabilities during our tests with moving faces, in which the Mi MIX 3’s exposure adaptation doesn’t quite keep the subject well-exposed (see the end of the sample clip below).


Color rendering is also decent in all lighting conditions, and white balance is particularly good under indoor and outdoor lighting conditions, with a few color casts creeping in low-light videos. The same applies to color uniformity, which is good indoors and outdoors, but slight differences in color between the center and edges of the frame start to become noticeable in low-light videos.

As with stills, the fixed-focus lens ensures good sharpness on faces at close range, so it’s best to fill the frame and shoot your video calls at around 30cm. Doing so ensures that facial details are nicely preserved, but again, that limited depth of field means that backgrounds or faces that are beyond the optimal 30-55cm distance range are noticeably out of focus.


Stabilization on Mi MIX 3 video is pretty efficient—the system works well at stabilizing your footage, but some movement is still visible, as you can see in the sample clip below.

Xiaomi Mi MIX 3 camera review (originally published Oct 25, 2018)

Announced today, the Xiaomi Mi MIX 3 is the Chinese manufacturer’s latest high-end smartphone. The device is powered by Qualcomm’s top-end Snapdragon 845 chipset, and features camera hardware that is identical to some previous models, such as the Mi 8 or Mi MIX 2S, both of which were launched earlier this year.

The rear camera comes with a main 12Mp wide-angle camera, featuring a 1/2.55″ image sensor, an f/1.8-aperture lens and optical image stabilization. The secondary tele-camera is not optically stabilized and offers a roughly 2x zoom factor and a slightly slower f/2.4 aperture. A dual-LED flash unit helps light your subjects in dim conditions. Read our full report to find out how the Mi MIX 3 performed in our testing.


Key camera specifications:

  • Dual camera with wide-angle main and secondary telephoto lenses
  • OIS on the main camera
  • Phase detection autofocus
  • Qualcomm Snapdragon 845 chipset

Conclusion

Packing the same camera hardware as the Mi 8, Xiaomi’s latest smartphone has managed an improvement in its photography capabilities with modifications to its software and image processing algorithms. For still photos, it’s up there with some of the best devices we’ve tested, with good color, dynamic range, texture, and flash performance. Video performance is very similar to the Mi 8’s, although improved stabilization gives the Mi MIX 3 an advantage when shooting low-light movies. In short, the new Xiaomi is an excellent all-rounder.

Pros

  • Fast, accurate, and repeatable autofocus
  • Accurate white balance with bright, vivid colors
  • Wide dynamic range in outdoor and indoor shots
  • Excellent flash performance

Cons

  • High level of noise in high-contrast scenes
  • Inconsistent bokeh in Portrait Mode
  • Color banding visible in some indoor scenes

Cons

  • Visible noise in low light
  • Autofocus errors with scene changes
  • Exposure steps visible during convergence
