The birth of the telephoto lens satisfies people's desire to record further scenery. In the early years, professional SLR telephoto lenses were necessary to get pictures a few kilometers away, but for the average user, it not only required expensive equipment costs, but also had high requirements for shooting technology. But advances in technology can always go far beyond the imagination,A few years ago, who could have thought that today's smartphones could also achieve 10x optical zoom and 100x digital zoom, leaving a million meters of beauty in front of them?

In recent two years, with the rapid development of smart phone photography, each mobile phone manufacturer has different development directions, but it mainly solves two user pain points,One is to shoot more clearly, the other is to shoot farther. At

Since last year, the mainstream first-line mobile phone manufacturers have made frequent efforts in the camera zoom capability of mobile phones. From the early 3x and 5x zoom, they have developed to 10x, 50x, 60x and even the most powerful 100x zoom at present.Of course, there are also differences between zoom and zoom. From the perspective of zoom principle, it can be divided into optical zoom, hybrid zoom and digital zoom.

What is the difference between the three zoom modes? each of the three zoom modes has advantages and disadvantages.In short, optical zoom is a lossless zoom. Optical zoom relies on the movement of the telephoto lens and the refraction of light, so as to make the distant scene closer. Therefore, the picture is basically lossless and presents the best picture quality。 But the disadvantage is that the lens size will be limited by the space of the fuselage, and it can't be zoomed too high.

Digital zoom is also very common, it is from the way of software calculation, through the way of difference, clipping, etc., to increase the unit pixel area, so as to achieve the effect of distant picture magnification. This kind of zoom is simple and rough, the advantage is that it is easy to achieve high zoom, but the disadvantage is that the quality of the picture will be lost, a lot of screen details will be lost after magnification can not see clearly.

Hybrid zoom is a new zoom mode in the last two years. In short, it combines optical zoom with digital zoom, which is a fusion scheme . When the mobile phone takes pictures, once the shooting distance exceeds the physical zoom distance of the mobile phone lens, it will switch to the digital zoom, and the image is calculated by the algorithm, and the final image quality is between the optical zoom and the digital zoom.

From this point of view, optical zoom is the core that can really guarantee the quality of telephoto photography, plus the auxiliary of mixed zoom, digital zoom, is the best mobile phone zoom solution.

However, the physical characteristics of lens module (the longer the focus section, the longer the module) are inconsistent with the appearance ID design of mobile phone. The optical zoom of 10 x magnification means that the equivalent focal length is greater than 200 mm, the actual physical lens module has a focal length of about 28 mm, a very large volume。 According to the quantization standard, it is impossible to realize 10 times optical zoom according to the traditional lens structure. Therefore, improving the lens structure is the only way to achieve it.

Always the first in the photo field HuaweiP series of mobile phones first broken. Last HuaweiP30Pro ,Huawei first tried the periscope lens to achieve five-fold light change.

Simply put, the CMOS image sensor is placed vertically in the mobile phone, and is aligned with the lens along an optical axis parallel to the fuselage. Then, a mirror is used to reflect the light entering the camera to the lens and the image sensor, so as to create a longer equivalent focal length than the installation direction of the traditional camera (i.e. facing the outside on the surface of the mobile phone) 。

However, even through the reflector, it is still difficult to achieve 10x light change. When a beam of light enters the phone, how can the optical path be as long as possible? The total length of the optical path is positively related to the physical focal length, either the phone becomes thicker or the light turns. x optical zoom of 10 magnification means an equivalent focal length greater than 200 mm, a physical focal length of about 28 mm.. The total optical path length of the HuaweiP40Pro is 2.78 times that of the HuaweiP30Pro periscope lens. Modular length can not increase significantly, so optical architecture, only periscope reflection is not enough at one time, the optical path must be reflected multiple times.

To this end ,HuaweiP40Pro created a multi-reflective periscope super-long focus camera, which realized 5 optical path reflection, the optical path is 178% higher than the previous generation periscope long focus, so as to achieve 10 times optical zoom of equivalent 240 mm and 100 times digital zoom with higher multiple optical end.Along the direction of the main optical axis, the 10 times optical zoom camera module is divided into several parts, which are: reflection surface, optical lens component, light adjustment component, driving component, image sensor. In this way, it not only effectively eliminates the distance limitation and can see farther, but also effectively balances the difficulty of the thickness space design of the mobile phone body.

The realization of a 10-fold zoom lens also raises the question of how to achieve a smooth transition when zoom is used.HuaweiP40Pro also added a 3-fold optical zoom camera, two zoom cameras constitute the industry's first ultra-long-range binocular zoom system. The two cameras both performed their respective duties and worked togethe10x Optical Zoom Camera Equivalent 240 mm, Innovative

Furthermore, on the basis of the 10x optical zoom to ensure the quality of the mediumand-long-focus segment ,HuaweiP40Pro to achieve a further zoom distance ,20x hybrid zoom (three cameras achieve excellent 20x zoom effect in various environments through different combinations), and 100x ultra-longer digital zoom greatly expand the user's photo field of view.

100x zoom what concept? And it's equivalent to mm 2300 focal length, so

How tough is the HuaweiP40Pro's real shot? To feel it.

Five of the six zooming images show the charm of HuaweiP40Pro 100 times digital zoom, see clearly just a row of ordinary tall buildings, with zoom magnification, unexpectedly saw a small artificial lake between buildings, magnified to 100 times even found a man and a woman on the bridge.

And in another set of actual photos, looking at a beach, normal shooting can only vaguely see the beach tent. At the HuaweiP40Pro's telephoto end, you can see the details of the beach chair, and even see if there is anyone lying on it.

Except for implementationAlso, the photographer captured the amazing coincidence of the International Space Station moon through HuaweiP40Pro 100x zoom. Even more eye-popping is the ability to see the moon moving slowly and feel the earth's rotation through HuaweiP40Pro 100x zoom.

For ordinary users HuaweiP40Pro 10x optical zoom and 100x digital zoom allow you to experience the pleasure of telephoto photography without professional photography and without having to pay too much for it. Aside from professional photographers, images carrying heavy equipment may become less and less common as HuaweiP40Pro arrive.

And in terms of the significance of the development of mobile phone photography ,HuaweiP40Pro exploration of the mobile phone's extreme telephoto ability is undoubtedly a feat, put in the whole history of mobile phone photography, but also enough to draw a heavy stroke. Now, if you are interested in HuaweiP40Pro, this is the best time for you to start, the current online purchase can enjoy 24 installments free, from 5.74 yuan a day, you can enjoy HuaweiP40 series of 5 G mobile phones, the opportunity is rare, do not miss.
