The flagship version of vivo NEX has successfully hit the 4000 yuan mark. Even though the price is higher than most domestic flagship ships, it can still win a good bid. The flagship series of vivo always stops changing from time to time. After the Xplay6, the NEX flagship version of the optical anti shake IMX363 is brought. This time, we found the same brand of vivo X21 for comparison.

The main camera hardware of Xiaomi MIX 2S and NEX flagship is almost the same, both of which are optical anti shake IMX363. Although it is surpassed by IMX600 series and IMX377/378/380 series, the 1/2.55 "sensor is the limit of most optical anti shake modules. The two series of sensors above are both 1/1.73" and 1/2.3 "in size, and few can carry optical anti shake.
For daily use, optical anti shake can greatly reduce the chance of hand shaking the film, which is a camera configuration very suitable for public use. Therefore, compared with the IMX377 series, the author actually supports the "optical anti shake 363" scheme. Although the unit pixel is from 1.55 μ M shrinks to 1.4 μ m. But with anti shake and dual core focusing, the exchange is still worth it. Unless it is up to the crazy size of IMX600, this scheme is still stable.
Here is an interesting detail. Xiaomi 8/MIX 2S and vivo NEX are similar in wide angle, but in terms of physical focus, the flagship version of NEX is larger.
Investigation items and scales
The core of mobile phone photographing is the photographing experience and imaging effect. The main factors that affect the experience are: Smoothness of shooting and film consistency , whether the viewfinder box has problems such as delay/shadow dragging/frame dropping/noise full screen; speed , including focusing speed, shutter response, and imaging speed; Film rate , the probability of destroying the film by shaking hands; Intelligence, Whether the scene with large light difference and weak light can be recognized, and HDR and night view mode can be automatically triggered.
The imaging effects mainly include:
White balance and photometry : In many scenes such as sunlight/light/weak light and extremely weak light, whether the white balance (picture color and wind direction) and brightness can be close to the naked eye;
Tolerance: That is, the ability to show the details of the light and dark at the same time. For mobile phones, this is basically equivalent to the HDR effect, including the size of the processing force, whether the processing is natural and harmonious, whether there is ghost after synthesis, white balance deviation and the decline of discrimination;
Discrimination: Roughness can be understood as clarity, and the sharpness, detail and naturalness of the picture must be taken into account at the same time;
The remaining assessment contents include noise control, color saturation, lens quality (including edge degradation control, anti glare, fog control, wide-angle and pillow distortion control, etc.) and many other contents.
There are objective standards for good photography, but the high saturation, high contrast and filtering of mobile phone imaging in recent years indicate that the mainstream has begun to develop in a pleasing direction. Even the iPhone began to deviate from the official restoration route, and various Leica and AI filters appeared, which added the color of "aesthetic metaphysics" to camera photography.
However, in the face of the same set of comparison proofs/the same objective fact, people with different evaluation systems, preferences and ideas will inevitably have different, or even opposite, views. For different users, the proportion of different projects is completely different: the Maoist Party, which likes to zoom in and scan, will definitely put discrimination first, and the proportion is very high; If it is mainly used for sunning in the circle of friends, it should pay more attention to tolerance, white balance, saturation and other items; The final effect is just as good as everyone likes it. Just focus on what you care about.
Special instructions, wide angle and virtualization
It should be noted that since vivo started with X21, photos and screenshots are output in P3 standard. NEX did not accidentally continue this practice. Both machines are full automatic HDR. The focus is always at the center.

The wide angle/field of view of vivo X21 and vivo NEX are very close, both of which are large wide angle types.
Dummy sample comparison
Whether the virtualization effect is natural is directly related to the precision of matting algorithm and the intensity of virtualization. If the camera itself is a long focus and large aperture, the effect of optical virtualization will be superimposed, which will be more advantageous. The virtualization effect of X21 and NEX flagship is similar, which is more than enough to deal with the circle of friends, but the experience is very different. The virtualization response and imaging speed of NEX flagship are significantly faster.

The metering and white balance of the two machines are somewhat different, and NEX is closer to the naked eye. After the HDR is triggered, the difference between the appearance of the two machines is smaller, and the NEX with higher local tolerance is obviously dominant in the dark details. In addition, the two vivo mobile phones have obvious sharpening, and the white edge of the object edge zooms obviously after zooming in. This can improve the clarity of the first impression, but also make the picture hard.

After the light starts to deteriorate, even if the ISO is close, the noise control, detail performance and contrast performance of NEX are beginning to diverge from X21.

Large light difference weak light scene with complex point light source. The performance of the flagship version of NEX is incredible. In this scene, only P20 Pro has had similar performance. The edge of the object is clear and sharp, the contrast is high, and noise can hardly be seen. If there is not a sample of a normal mobile phone beside it, I think there is something wrong.

Even if the shutter is opened for 1/4 second, NEX's film rate is still high. Even if the light is weak, the 12 million pixel discrimination is not much worse than when the light is good.

There is no anti shake. The X21 with the slowest shutter speed of 1/14 seconds kneels down here. The NEX flagship uses the optical anti shake IMX363, and has pushed the equivalent shutter for 1/4 second, which is the opening and closing of the red fruit. This is a scene where the naked eye can hardly see the light. The exposure of X21 is only slightly lower than that seen by the naked eye, while NEX is obviously "overexposed". These are the details of the scene that cannot be seen by the naked eye.
summary
vivo X21 : What makes the author most profound is the shutter response and imaging speed. This year The shutter is made like a machine gun There are not many mobile phones. Even though the algorithm is good, it is hard to fight with NEX when the light is weak due to hardware limitations. The weak light scene is underexposed, noise control, and dark details are all normal 。 Without the "small bottom" of optical anti shake, it is impossible to break the "dimensional wall" of hardware configuration, but it has exceeded expectations to do so.
NEX Ultimate : The camera experience and imaging style before triggering HDR are similar to similar sensors Xiaomi MI X2S, but the metering and white balance should be more accurate. After triggering HDR and night scene multi frame synthesis, the picture style is very similar to vivo X21, but the tolerance has been significantly improved. Vivo's HDR (officially called "backlight") is a typical flattering style, which will significantly improve the overall brightness of the picture, and the white balance will be warmer and yellower (X21 is green).
In the daytime and under strong light, the discrimination power cannot be separated from X21. Although they all have obvious sharpening marks (after zooming in, the edges of objects will see obvious white edges), and the contrast is slightly higher The painting force is too heavy, and some picture details are erased 。
But the extremely weak light scene has become the home of NEX flagship without warning. Although the photographing experience under extremely weak light is average, and the shutter response is slow, the viewfinder is very stable, and there are few Android phones with such film rate when the "equivalent shutter" is pressed to 1/4 second.
The extreme low light performance of the flagship NEX is "strong" in one word, and "open" in two words, 99% of the weak light night scenes of mobile phones on the market will be rubbed on the ground by it. The noise reduction coating of the flagship NEX is very clean, with complete discrimination, and better contrast and highlight suppression. The last mobile phone to achieve this level of weak light imaging is called P20 Pro.
