Periscope system on P30 Pro

Huawei placed a telephoto lens horizontally in the housing, thus providing more space for the lens system to achieve a longer focal length. All this is achieved by a prism that reflects the light beam 90 degrees. Therefore, Huawei and Leica continue to point the way for the entire smartphone industry in camera shooting. P30 Pro is the world's first smart phone with 5x optical zoom and long focal length 125mm. In order to install so many lenses in such a thin smartphone case, Huawei used a periscope system used by submarines. It can be expected that this technology will become a textbook for mobile phone camera shooting.

The zoom shooting quality is amazing.

The focal length range of P30 Pro is 16 to 125mm, which opens up new possibilities for smartphone photography. Standing in the same position, you can not only shoot big scenes, but also zoom in on distant details.

This can be illustrated by comparing with iPhone XS Max: Apple doesn't have a super wide angle, and the picture taken is not as wide as Huawei's.

IPhone XS Max can't zoom the distant details so close through 2x optical zoom.

Oppo, a mobile phone manufacturer in China, demonstrated a similar system at the Mobile World Congress in 20 17, but it was never mass-produced. This is not surprising, because the orderly layout of so many lenses and the instability that increases in proportion to the focal length are extreme challenges faced by engineers, and the required processing technology and technology must be particularly precise.

Huawei and Leica did it: P30 Pro is the first smart phone with a focal length of 125mm, which is nearly five times the standard focal length of 27mm. The result is naturally extraordinary. So far, I haven't heard of any smartphone that can achieve zoom quality comparable to P30 Pro. Other top mobile phones, such as iPhone or Samsung Galaxy S 10+, must be digitally enlarged to achieve similar zoom magnification, but this will inevitably lead to a sharp decline in image clarity. On the contrary, P30 Pro can take great photos-of course, under certain conditions: the light needs to be captured for a longer time, so the sensitivity of the sensor cannot be particularly strong (aperture F3.4), which means that the illumination must be good. At dusk or in a dimly lit room, 5x zoom is impossible.

The fourth camera of P30 Pro

The periscope zoom system is equipped with a 20-megapixel super wide-angle lens (16 mm focal length) and a 40-megapixel wide-angle lens. This structure has appeared on Mate 20 Pro launched in June, 20 18. But P30 Pro added a fourth sensor, the so-called TOF (Time of Flight/) camera, to measure the distance in the room. This is not only to improve the quality of portrait on fuzzy background, but also to significantly improve the accuracy of AR (Augmented Reality Technology) application. An example of this is Huawei's application "AI Measure": you can accurately measure the distance between furniture and other objects just by holding your smartphone-to the millimeter. We took a lot of samples with P30 Pro, but unfortunately we didn't find any improvement in portrait quality-because Huawei only announced (but hasn't implemented) the corresponding software update.

Upgraded super wide-angle lens

Compared with Mate 20 Pro, the ultra-wide-angle shooting quality of P30 and Pro is improved: there are fewer lens halos, and the distortion and detail loss in the edge area of the image are less obvious. Especially in low light conditions, the image quality of standard focal length photography has also improved.

Improved night shooting mode

Last year, the night shooting mode, which caused a sensation when P20 went on the market, was improved again on P30, so it can capture more details in the dark than most other smartphones. This not only benefits from the improved algorithm, but also benefits from the new image sensor. Its built-in Bayer filter has defined the processing method of color information for decades, but it was further improved by Huawei: Huawei opened a very large bucket to absorb light, and replaced the green in the classic red, green and blue matrix with yellow, because the spectrum of yellow is larger, which eventually increased the light captured by the sensor. "In order to achieve this goal, we must redesign the camera module, which is an extremely complicated and laborious project," explained Henkelmann, head of Huawei's European smartphone development. There is no doubt that Huawei's efforts are worthwhile, because it has designated the direction of camera development for the entire smartphone industry.

Even in the dark environment, P30 can shoot clear and colorful images with outstanding quality. Competitors such as Apple and Samsung may have to admire the leading edge of P30 Night Shooting.

Camera summary

The test results give a clear conclusion: the combination of image quality, adjustment depth and focal length range makes P30 Pro a smart phone with the best camera, which other competitors can't catch up with and still need to catch up closely. People who don't want to compromise on the camera, I'm afraid they can only "not take P30 Pro".

Although Huawei P30 is not ahead of its competitors like Pro, it is still among the best. Lack of TOF ranging lens, not 5 times zoom of horizontal structure, but 3 times optical zoom (80 mm focal length) is enough for daily use, and the image quality has reached the top level. In other words, you spend 750 euros to get a camera, which can not only shoot high-quality images like the iPhone XS, but also shoot in a larger focal length range (17-80mm), with wide angle and 3x zoom.

However, Huawei's excellent camera system has a disadvantage: whether it is P30 or P30 Pro, its camera unit protrudes nearly 2 mm from the chassis, and Huawei does not put the lens in the middle position on the back (such as Mate 20), but in the upper left corner, so the mobile phone will tilt on the desktop. The three cameras of Samsung S 10 model are well matched with the chassis and can lie on the desktop smoothly. In order to adjust the inclination, P30 needs a mobile phone case (not included) to help.

Unlike Samsung and other companies, Huawei still insists on Liu Hai's design: there is a gap at the top of the screen for placing the front camera. The notch is water-drop shaped and very small, which has no disadvantage compared with the front camera directly embedded in the screen (such as Samsung S 10 or Glory View 20).

China brand also didn't compete for the highest resolution-unlike Samsung and LG using Quad HD display on their high-end mobile phones, P30 screen "only" provides the Full HD resolution of 2340x 1080 in 19.5:9 format, which is too small to be distinguished from Quad HD by naked eyes.

The display quality measured in the laboratory is excellent, and the 6.5-inch screen contrast ratio of P30 Pro is 1: 9999 (

P30' s 6. 1 inch OLED display has a contrast ratio of 1: 9999 (

Huawei's Kirin 980 processor has a neural core for machine learning and is the most advanced of its kind. 8 GB working memory RAM(P30 reduced to 6 GB), and the performance of the two new machines is unparalleled. Huawei interface EMUI 9. 1 Nothing new except updating icons.

The fingerprint sensor is directly integrated under the display screen, which not only saves space, but also has a more airtight structure. At present, fingerprint identification can be divided into the following two technologies: optical scanning of skin by optical sensor; Send high-frequency sound pulses to the finger direction for ultrasonic scanning. Ultrasonic scanning is considered safer because it creates a three-dimensional image of the fingertip and is also suitable for wet hands. Samsung's latest flagship Galaxy S 10 uses ultrasonic scanning, while Huawei chooses optical scanning. In daily use, the fingerprint of S 10 is unlocked a little faster than P30.

Of course, you can also unlock P30 by sweeping your face. However, the face recognition of P30(Pro) is not as safe as Mate 20 Pro of iPhone and Huawei, because the front camera only detects two-dimensional face images. Therefore, when the light is bad or the angle is unfavorable, it is often impossible to recognize the face. If you value safety, you can not activate facial scanning. Of course, a combination of face and fingerprint can also be used.

P30' s optical system layout, back glass and anodized aluminum frame all come from its previous generation products, but its feel and workmanship are more delicate. The frame design is excellent: the long side adopts ergonomic circular design; The short sides of the top and bottom are ground flat, so the mobile phone can stand upright. In direct contrast, P30 Pro with curved screen looks more modern than P30. Although the latter has a 6. 1 inch display screen, it is still very compact because the display screen is close to the frame.

On P30, Huawei gave up the IP68 waterproof and dustproof certification and replaced it with a lower IP52 level. We think this is a mistake, because within the price range required by users, users' mobile phones should be waterproof for a short time after falling into the water. Fortunately, P30 Pro did it.

For audiophiles, P-series mono speakers and relatively low voltage output (which makes high-quality wired headphones fail to play their potential) are not the first choice. In addition, Huawei omitted the traditional speaker on P30 Pro, and let the screen glass vibrate instead. When the ear is in direct contact with the display glass, the sound transmission effect is the best-this is called body sound transmission. But the call volume measured in the laboratory is relatively low, which proves that this is not a good idea.

The attached earplugs can't be firmly fixed in the cochlea, so you will soon want to change a better pair of headphones, which is no problem for P30 with headphone jack, but Pro doesn't have headphone jack, so the types of headphones you can choose are limited.

On the contrary, the sound of P30 is top-notch, reaching the usual high level in the industry, especially the effective suppression of background noise (one of Huawei's strengths). This dwarfs your Pro, losing to P30 by a considerable 3 points in comprehensive score, thus falling behind 4 places in the ranking.

Usually, the sending and receiving ability of the same mobile phone is different in different network environments, which can be displayed by the directional map measured in the laboratory showing the sending and receiving of signals in all directions of the smart phone. Red areas far from the center point indicate strong signals, yellow areas indicate medium signals, and green and blue areas indicate weak signals. Therefore, the redder and rounder the pattern, the stronger and more uniform the signal sent and received by the mobile phone.

In terms of wireless signal transmission and reception, Huawei is as blameless as ever.

10 hour, 13 minutes (P30) or1hour 3 minutes (P30 Pro) is enough to make you spend a long day easily. Compared with P30 Pro equipped with 40W fast charge, it can charge 70% in 30 minutes. The P30 comes standard with a 22W charger, but this is not a real short board. Testers deeply regret that P30 lacks wireless charging standard Qi possessed by Pro, so it cannot be used as a mobile power station to charge other mobile phones and accessories like Pro. Of course, the excellent overall impression will not be dim.

Huawei's new P-series models once again get what they want: photographers can't do without P30 Pro, which is a compact and multifunctional product with no blameless weakness, and the price of 750 euros is really favorable. But the technical level of high-end smartphones is so high that even small mistakes will be punished. P30 Pro lost 3 points for giving up the talking speaker. Coupled with Huawei's long-term weakness in sound quality, P30 Pro failed to make the list, only ranked sixth, four places behind P30Pro!
