1. Foreword: Xiaomi 12S Ultra debuts with a 1-inch sensor for the first time Leica
known as the "Light of Android" Xiaomi 11 Ultra A year after its launch, rice fans did not see Xiaomi 12 Ultra, but directly welcomed it Xiaomi 12S Ultra.
According to XiaomiCEOLei Jun, the next breakthrough direction in mobile phone imaging technology is optical lenses. Xiaomi 12S Ultra also teamed up with Leica for the first time to create SUMMICRON in mobile phone lenses.
From Xiaomi 10 Ultra to today's Xiaomi 12S Ultra, it can be seen that Xiaomi has invested more and more in self-developed technology. The Ultra model has become Xiaomi's experimental field for new imaging technologies, vowing to establish an imaging flagship Benchmark.
Now, our Kuai Technology has received this Xiaomi 12S Ultra.
In recent years, the optical lenses used in flagship imaging mobile phones can be divided into three camps: Leica, Carl Zeiss, and Hasselblad. All major manufacturers have joined forces with them for in-depth training, each showing their unique abilities, and many mobile phones have become "camera".
Xiaomi 12S Ultra is equipped with a Leica professional optical lens, and for the first time brings a 1-inch outsole Sony IMX989 sensor. This is the first time that mobile phone sensors have exceeded the 1-inch level in many years, comparable to the card machines of the year.
At the same time, Xiaomi has also carried out in-depth cooperation with Leica and Sony to open up the entire link in software and hardware to provide users with an excellent photography experience.
With a good camera, the 6.73-inch Dolby Vision primary color screen is the icing on the cake. The AMOLED panel made of Samsung E5 uses LTPO technology, with a resolution of 3200×1200, 1~120Hz intelligent dynamic refresh, native 10bit color depth, and P3 color display, which can truly restore the true effect of the camera.
In addition to cameras and screens, Xiaomi Mi 12 Ultra also continues the feature of extreme stacking. Snapdragon 8+ processor, 6400Mbps LPDDR5 memory, and UFS 3.1 flash memory form a new generation of flagship three-piece set . The only regret is the 67W fast charge A little slower.

3. Image specifications: First IMX989 one-inch outsole sensor and Leica optics cooperate in depth
Xiaomi 12S Ultra equipped with Leica Summicro 1:1.9~4.1/13-120 ASPH. Lens system Leica professional optical lens, to put it simply, it is an optical lens + The combination of sensors and the in-depth integration of software and hardware can be called a "lens system".
The lens system of Xiaomi 12S Ultra covers the entire focal length range from 13mm to 120mm, bringing more possibilities for shooting.
- Lens analysis
One of the key points of Xiaomi 12S Ultra is the "imaging super flagship", which is equipped with Sony IMX989 sensor. This 1-inch sensor is also the largest ever on a mobile phone, bringing excellent noise control capabilities. The ultra-large dynamic range and photosensitivity have been improved by 67% compared to the Mi 12S. In terms of
specifications, the Quad-Bayer pixel array is known to the public as four pixels in one, and the fused pixels have reached an unprecedented 3.2μm.
plus a 48-megapixel 1/2-inch ultra-wide-angle lens and a periscope telephoto lens form a three-camera solution. Even the IMX586 sensor used on most mobile phones has given way to the secondary camera here.
Xiaomi Mi 12 Ultra’s 1-inch outsole Sony IMX989 sensor takes advantage of the fact that it is “big enough to crush people”. As we all know, the larger the sensor, the larger the photosensitive area, the better the photosensitive performance, and the better the imaging effect. The better.
Xiaomi CEO Lei Jun also said that this 1-inch model has not undergone any cutting and is the ceiling of current mobile phone imaging hardware.
Xiaomi 12S Ultra is also equipped with Leica professional optical lens, which makes the picture purer and has higher imaging latitude, which is invincible in affecting the experience.
Xiaomi 12S Ultra uses double-sided ultra-low anti-reflective coating on the entire lens, which can be applied edge-by-edge. A new type of cyclic olefin material is also added, with a reflectivity as low as 0.2% and a light transmittance as high as 93%, which can reduce glare and eliminate purple edges.
For users who often shoot, purple edges often appear on the edges of objects in various environments. The reason for this problem is related to the dispersion of in the camera lens, the signal processing algorithm inside the camera, etc. Even a SLR is difficult to avoid.
The Leica optical lens equipped with Xiaomi Mi 12S Ultra has additional cyclic olefin material, which makes it effective in absorbing ultraviolet light. This greatly reduces the probability of purple fringing and makes the picture purer.
