With the growth of smartphone sales brought by celebrity effect and advertising endorsement, Xiaomi finally cannot stand still. Hongmi Pro is Xiaomi's first smartphone with celebrity endorsement, and it also uses three celebrities to endorse it. Because of the additional cost of star endorsement, most smart phones will also reduce the material cost to increase profits, thereby reducing the cost performance of mobile phones. Although the Hongmi Pro is not so obvious, from the perspective of configuration, it does not have the "cost performance" of Xiaomi in the past.
The Hongmi Pro adopts dual rear cameras, one with 13 million pixels (IMX258) and one with 5 million pixels. However, its scheme is different from that of Huawei P9 and 360 Qiku mobile phones, which use black and white cameras and color cameras. In this comparative evaluation, we selected Xiaomi 4c, Xiaomi Max and Hongmi Pro, and the main test content is still the comprehensive ability of day and night imaging of Hongmi Pro.
Double lens
Imaging of samples taken with dual lenses under different electronic apertures
It can take pictures before focusing, and adjust the background virtualization range through the electronic aperture
This dual lens scheme of Hongmi Pro has appeared in the market for a long time. The dual lens can calculate the depth of field within a certain range. By adjusting the depth of field to simulate the large aperture background virtualization of the camera, you can also take photos first, then focus and adjust the aperture. Of course, the dual lens effect on the Red Rice Pro is the same as that of most dual lens mobile phones. The effect is poor, and the blurring cannot ensure the integrity of the edge of the object. At first, it is the kind of blurring on the PS. There is a feeling of low~low after the big aperture is blurred, let alone the SLR. This kind of random effect is not as good as using the ordinary mode honestly.

In the first set of scenes, the white balance performance of the three is different. Xiaomi Max is red, Xiaomi 4c is cold, and Hongmi Pro is relatively close to reality, but there are also deviations. In terms of analytical power, Xiaomi 4c has obvious advantages. In terms of font analysis of "Rongyue Restaurant" in the distance, Xiaomi Max and Hongmi Pro not only lack sharpness, but also lack of pixels.

In this group of scenes, the white balance of Xiaomi 4c has a problem again. The overall color temperature is cold, which is quite different from the color of the real scene.

Due to the sufficient light in the outdoor scene, the main competition in the daytime scene is resolution, followed by white balance. Although Xiaomi 4c has only 13 million pixels, due to its large focal length and small viewfinder range, it has obvious analytical advantages over Hongmi Pro even in the same scene. This analytical advantage has even exceeded Xiaomi Max with 16 million pixels. However, in terms of white balance, the white balance of Xiaomi 4c has shifted even in daytime. The outdoor daytime exposure control of the three is poor. In the case of intense sunlight, there will be obvious picture overexposure. The performance of Hongmi Pro is relatively ideal.

In this group of proofs, their anti glare ability to distant point light sources is relatively poor. All three have serious glare and light spots, the most serious ones are Hongmi Pro and Xiaomi Max, and the glare has affected the imaging of the whole proofs. Although Xiaomi 4c also showed glare and light spots, the degree is not as serious as the other two.

In the outdoor night scene, Xiaomi 4c is still the best, followed by Hongmi Pro. Xiaomi 4c is far better than Hongmi Pro and Xiaomi Max in anti glare ability. The performance of the Red Rice Pro is not very stable. The Red Rice Pro takes multiple shots in the same scene, and different sample images will appear. Sometimes it will increase the noise and enhance the analytical power, and sometimes it will reduce the noise and reduce the analytical power by smearing.

The red circle is the range where the left edge of Hongmi Pro is out of focus
In the process of taking photos, we accidentally found that the image quality of the left edge of the red rice Pro on hand would be out of focus, and the analytical power would decline seriously. Moreover, the reproduction rate of the red rice Pro on hand was 100%, which means that every sample would show such a problem. Since we have only one Hongmi Pro on hand, we are not sure whether this problem occurs in a large area. We need to contact Xiaomi Mobile Phone Company to determine.
summary
Both the Hongmi Pro and the Xiaomi 4c (our 4c is the IMX258) use the IMX258, but there are obvious differences in their imaging. The Xiaomi 4c with a price of 1099 yuan has better performance, while the Hongmi Pro with a price of 1499 yuan still has the same imaging level as the Hongmi series. Although the price has increased, the quality has basically remained unchanged.
