Ride on the dust! Huawei P40 Pro supports 10x optical zoom: a breakthrough in mobile phone photography.

At noon, sweat dripped into the soil, but at lunch, there was baked sweet potato. This is the editor of Niu Zhan. He is hungry. I will tell you the news. The weather is good today. This is a good time to read the latest information and relax.

On the evening of March 26th, Huawei Mobile released its flagship Huawei P40 series in 2020 in the form of a global online conference.

In addition to P40/P40 Pro that consumers pay attention to, Huawei P40 Pro, a new member of Huawei P40 series, supports 10x optical zoom, which has attracted the attention of the whole industry.

Today, the industry is still dominated by 3x and 5x optical zoom. Huawei released 10x optical zoom for the first time, which can be said to lead mobile phone photography again.

As a technology product with small volume and high integration, it is very difficult to design the optical path supporting 10x optical zoom.

How is Huawei P40 Pro realized?

The official explanation is that through the super telephoto structure of the periscope with multiple reflections, the optical path is extended through five reflections, which increases the optical path by 178% compared with the telephoto of the previous generation periscope. This is also a new technology created by Huawei and applied for a patent.

There is no simple technology behind the seemingly simple text summary. Through the structure diagram, we can see the track change of the light path, which is much more complicated than the previous generation.

Another difficulty that needs to be overcome is the optical path distortion after repeated refraction, which requires accurate control of the mirror assembly plane in the module.

How difficult is it? In fact, the biggest difficulty is that there are no historical and technical cases to refer to. For the pioneers, everything needs to be explored by themselves.

According to Huawei's camera team, after continuous testing and optimization of various schemes, the final optical path refraction accuracy is controlled at about 30 nanometers.

For example, the data that users can perceive is about one thousandth of the diameter of human hair. It is conceivable that such technical difficulty, especially considering the problem of mass production.

10x optical zoom is more difficult than solving the optical path problem. The longer optical path makes the lens see farther, but focusing is another key factor to get a clear picture.

At present, the telephoto lens in mobile phones is generally slower than the main camera, especially when shooting moving objects, it is easy to lose focus. How does Huawei P40 Pro solve this problem? The answer is chute AF long-life motor.

In order not to interfere with the complicated optical path design, the motor of telephoto lens can only be designed behind the reflector.

Similar to the problems encountered in optical path design, after repeated verification without any reference scheme, the engineer finally chose the chute bearing mode, strong magnetic force and precise lever structure, which skillfully balanced the load of the front mirror.

At the same time, excellent lubricating materials are used, so that the motor can move the mirror with high stability and high precision, and realize the automatic focusing function.

It is reported that this motor system has passed millions of tests and extreme environmental tests and has a long enough service life. Huawei also applied for a patent for the unique focusing motor of the module.

Huawei has not announced the research and development cost of this 10x optical zoom scheme, but it is certainly not low.

However, the result of huge investment is to push mobile phone photography to a new height. Although 10x optical zoom has just appeared, the biggest breakthrough in mobile phone photography in 2020 has been scheduled. This breakthrough, like the appearance of super night scenes, will once again promote the rapid development of mobile photography in the whole industry.

If you are a photographer who likes to take photos with your mobile phone, you must pay attention to the domestic conference of Huawei P40 series on April 8, when the domestic price of Huawei P40 Pro will be officially announced.
