Xiaomi Mi 12 Pro video review：The first IM707 sensor Android fastest camera speed
Although Xiaomi Mi 12 Pro does not continue to be equipped with the previous generation's super-large bottom main camera GN2，But the size of the first IMX 707 main camera is also not small.。 1/1.28The inch specification can be said to be second only to the GN2，The size of a single image element reaches 2.44 microns after the four-in-one image element。
also，Xiaomi Mi 12 Pro continues to strengthen the secondary camera，500010,000-megapixel ultra-wide-angle and 50-megapixel portrait lens，Both use Samsung JN1 sensor，Graphic element four-in-one equivalent graphic element 1.28μm，Can provide a clearer picture in good lighting，The quality of the two sub-cameras has been upgraded to a certain extent。
With the new Snapdragon 8's more powerful three-channel ISP，The experience of Xiaomi Mi 12 Pro in taking pictures has also been further enhanced。 This generation's photo speed is unparalleled，day or night，Even extremely dark scenes where other phones require 10-second long exposures，Xiaomi Mi 12 Pro's 50-megapixel triple camera can be achieved”out in seconds”。
also，There is also a focus tracking system based on CyberDog，Not only can the human eye、Follow-up photography of animal eyes，Can lock any object，Move freely to ensure that the focus is firmly locked，Make your video shooting and motion capture more comfortable。
No matter how the camera moves，can maintain focus，Great for snapping and video recording；Interested friends can also take a look at the evaluation of Sony mobile phone focus tracking。
next，Let's take a look at the photos of Xiaomi Mi 12 Pro directly from the proofs。
main camera auto mode：
imaging style，Mi 12 Pro is more natural，while improving the vividness，Imaging exposure is also controlled just right。 With its extremely fast camera speed，It's better to sweep the streets。
Horizontally compared to the previous generation，The winter sun at noon in the north is particularly dazzling，Directly lit areas and shadows are intertwined，It is easy to form a scene with a large light ratio，Even if this scene is a single-lens reflex，It is difficult to take a photo with the right light and shade without multiple exposures and post-compositing。However, the effect of the straight out of the phone is not bad，The overall look of the photo is almost the same as the naked eye。
However, the image quality of the GN2 main camera of the Xiaomi Mi 11 Pro does not have an obvious latitude advantage in this scene (but，This is also likely to be improved in later system upgrades) and，The imaging colors of the Mi 11 Pro are more vivid，The speed of taking pictures is also better。
In the field of mobile phone photography，It's not absolute to crush someone to death，algorithm，ISP performance，The lens will also seriously restrict the imaging effect.。
also，The clichéd issue of triple camera consistency。The Mi 12 Pro's full 50-megapixel triple-camera system，Consistent imaging style，Both the color and the light and shade are very similar，Almost cropped from the same photo，Only the focal length is different。
It is worth mentioning that，The 2x portrait telephoto lens on this generation of Mi 12 Pro。in poor lighting conditions，It does offer better sharpness than the main camera digital zoom。But if the light is good，The image in the main camera 50-megapixel mode will be clearer than the double portrait lens。
In this set of comparisons，5000The megapixel main camera is slightly better in terms of brightness and resolution。
After all, the main camera has double digital zoom at 50 million pixels，Either the 1.22µm unit cell size，or an effective resolution of 12.5 million pixels，Both are very close to the parameters of the double portrait lens.，So maybe a 2.5x or 3x telephoto lens would be a better choice。
Taking pictures at night，The Mi 12 Pro is just as good，All three rear cameras support night scene mode，and have excellent”second beat”speed。 At the same time, it also supports Ye Xiao 2.0 algorithm，Can better optimize the texture of lighting in low light，Make the picture more pure and beautiful。
In general，Although there is no super low GN2，But the IM707 is equally good。compared to the previous generation，The rear camera module of Mi 12 Pro is more balanced and perfect，in various scenarios，They all produce great photos in a consistent style，And has the imaging speed of seconds。
The only shortcoming may be that the 2x portrait overlaps with the main camera in some scenes in the focal length，It would be better if it could increase the focal length to 2.5 times or 3 times。
