What is the performance of Xiaomi MIX2S, which has taken the most photos in history?

Artifacts (that is, optical defects) will affect the image quality, and Xiaomi Mi MIX 2S has been deducted for artifacts. The main reasons for the buckle are purple edge, reduced sharpness, glare, ringing effect and dark angle. Some photos also have ghosts that look like halos or camera shake.

There are obvious purple edge lines on the rails.

There are also obvious color quantization and color bars on the indoor walls.

Flash (87)

Xiaomi MIX 2S provides accurate and consistent exposure between consecutive frames, and the dark angle and color vignetting are also well controlled, so it has achieved very good results in the flash test. White balance is generally accurate, especially when the flash is mixed with extra lighting, but in the photos taken only with the flash, yellow is a bit obvious, but it is not offensive. Xiaomi's noise reduction effect is good, so in all photos taken with flash, the brightness and chroma noise levels are very low, but the subtle details are not well preserved, and photos taken with flash only will also have red-eye effect.

When Xiaomi MIX 2S only uses flash (0 lux) to take pictures, the exposure is a little under-exposed, with a slight yellow color cast, but the noise and dark corners are well controlled.

Xiaomi Mi MIX 2S is a little underexposed when taking pictures with flash (0 lux) only, with slight yellow color cast, but the noise and dark corners are well controlled.

Zoom (42)

The telephoto lens of Xiaomi MIX 2S's sub-camera can show excellent details and resolution under short and medium zoom, so it has achieved good results in the zoom test. It can get the best shooting effect outdoors or indoors, but it will obviously lose details in extremely low light. Although we took some rather blurred zoom photos, we think this is caused by the failure of autofocus of telephoto lens, which is a pity because it really affects the quality of many zoom photos. If Xiaomi can solve this problem, it can really provide one of the best zoom functions in the smartphone market.

The short-range and medium-range zoom resolutions of Xiaomi Mi MIX 2S are slightly ahead of those of Apple iPhone X. Under medium zoom, the texture is quite in place under good lighting conditions, but some of the finest details are lost, while under extremely low light (5 lux), the shooting effect of close zoom is acceptable. However, under medium zoom, the loss of detail becomes more obvious, especially in extremely low light; Under telephoto zoom, only images taken under very bright illumination (1000 lux) can be used. In low light, there are a little more perceptible noises in middle-distance and long-distance zoom photos; Under various conditions, long-distance zoom photos have a strong ringing effect.

Scattered scenes (50)

Xiaomi Mimi MIX 2S has a strong but natural depth of field effect, good subject isolation and beautiful highlights. The results can be repeated in continuous photos, and only a slight inconsistency in depth of field estimation can be seen; Although the gradation of fuzzy gradient is good and the transition from foreground to background is smooth, you can occasionally see the gradient mutation behind the main body.

Xiaomi MIX 2S has a strong depth of field effect, but it looks natural.

The isolation of objects in static portraits is usually accurate, but the movement of some objects may lead to obvious and serious occlusion errors, thus destroying the photo quality, especially when the estimation of the depth of field of Xiaomi MIX 2S is wrong, and the strong depth of field effect will make this situation more obvious. As you can see, in our contrast photos, some edges of the subject are blurred. Even if you look at the image in a small range, the mask errors around the arms and railings are obvious.

There are some depth of field estimation errors in the shooting mode of Xiaomi MIX 2S.

Although the contrast photos of Apple iPhone X are not perfect, the mistakes are even less obvious.

Video scoring instructions

The video of Xiaomi MIX 2S scored 88 points. Although the score is good, the performance is not as good as that of still images. We use the scores of each evaluation item under the video to calculate the overall score of the video, which can let us know the advantages and disadvantages of the mobile phone when shooting moving images. Video evaluation items include: exposure (77), color (8 1), autofocus (90), texture (45), noise (75), artifact (79) and optical image stabilization (85).

The main video advantage of Xiaomi MIX 2S lies in its excellent autofocus system. Its auto-focusing is fast and accurate, and it has good tracking ability. Its electronic (EIS) video anti-shake system is also quite effective, thus reducing the jitter and tremor that may interfere with the viewing experience. Noise is well controlled, especially in outdoor movies. Although the video of Xiaomi MIX 2S has achieved a good balance between strong noise reduction and detail preservation, it has lost very fine details under all lighting conditions. The performance of target exposure under very balanced illumination is acceptable, but there will be some irregular exposure phenomena and some obvious exposure transition traces when the illumination conditions change, and its dynamic range is a little small, just like its static image. In some videos, there are also strong differences in definition between different frames, especially when recording videos indoors, but the colors are bright and the white balance is generally accurate.

Conclusion: Static images are excellent.

Xiaomi MIX 2S is equipped with top photography functions such as telephoto, shooting simulation mode, phase detection autofocus, and the latest and most powerful Snapdragon 845 chipset, which is enough to excite smartphone photographers. Because it can consistently take high-quality photos under various lighting conditions, realize ultra-fast and accurate autofocus, and present bright colors, it has achieved 10 1 in the photo test, which is one of the best mobile phones in our tested equipment. Xiaomi Mimi MIX 2S also achieved a good balance between noise and texture. Although its outdoor pictures do not show excellent clarity, its performance is not bad, and the shooting result in low light is one of the smoothest devices we have ever seen. If you want to buy a smart phone for video recording, the video quality of Xiaomi Mi MIX 2S may be quite average, but for photographers who shoot still images, this Chinese Pearl is one of the best mobile phones.
