Vivo X50 Pro evaluation: unexpectedly leading an era.

On June 1 day, the flagship X50 series mobile phone of vivo professional image was officially released. Among them, X50 Pro is equipped with ultra-sensitive micro-pan/tilt function for the first time, which breaks through the optical anti-shake and solid seal of traditional mobile phones, promotes the concept of lossless anti-shake of fuselage, challenges the physical limit and opens a new era of anti-shake of mobile phones.

So, what is the technical principle behind the ultra-sensitive miniature PTZ lens of vivo X50 Pro? Can this phone really help us record more beautiful nights?

Perfect image brought by miniature pan/tilt.

At present, the supplier of mobile phone CMOS sensor is either Sony or Samsung, and the imaging effect is more AI algorithm when the same sensor is matched. However, even the advanced AI algorithm needs to be based on the premise of stable shooting, especially in the process of super night scene and video recording, slight jitter will lead to weak picture content.

Super anti-shake function has become a battleground for military strategists.

In order to improve the anti-shake performance, the most popular technologies in mobile phone circle are EIS electronic anti-shake and OIS optical anti-shake. Among them, EIS mainly relies on calculation, using acceleration sensor and gyro module to detect the amplitude of mobile phone jitter to dynamically adjust the overall ISO, shutter and imaging algorithm for fuzzy correction.

The basic principle of OIS optical anti-shake function is to hang the lens. The system will convert the real-time jitter information monitored by gyroscope and acceleration sensor into electrical signal and electromagnetic force, and use a circle of magnets around the lens to give the lens a displacement with the same offset but opposite direction, thus offsetting the image offset caused by hand jitter.

EIS and OIS rely on "calculation" and "movement". Obviously, OIS who works harder is better. However, OIS optical anti-shake suspension lens is still not perfect. For example, its freedom of movement is limited in the XY plane, and the anti-shake angle is only about plus or minus 1, so it can only achieve a small range of translation movement. Therefore, OIS has little pressure to deal with small vibration, but it is difficult to compensate for large hand jitter. In addition, OIS floating lens and internal CMOS sometimes have different motion amplitudes, which leads to the loss of the picture.

The biggest feature of vivo X50 Pro is the introduction of a brand-new concept of "micro-pan-tilt super-sensitive lens".

Micro-pan/tilt technology is essentially similar to OIS optical image stabilization, but OIS optical image stabilization only realizes the suspension of the lens, while micro-pan/tilt technology suspends the whole camera module, thus changing the dimension of image stabilization.

According to the data given by vivo, the micro-pan/tilt lens module consists of a limiting mechanism, a double-ball suspension, a lens, a voice coil motor, a double S-shaped FPC cable, a T-shaped FPC, a magnetomotive frame and a protective cover. The miniature PTZ lens module can be miniaturized by stacking the magneto-dynamic frames with special-shaped structures, and finally it can be placed in the lightweight X50 Pro.

Compared with the traditional OIS optical anti-shake technology, micro-pan/tilt has an inherent structural advantage-lossless anti-shake effect. Technically, there is no relative displacement in the miniature pan-tilt module during anti-shake movement, but 100% module can realize anti-shake correction in multiple directions, and its rotation angle is as high as plus or minus 3, which is three times that of traditional OIS optical anti-shake. The motion amplitude of the whole camera module and CMOS sensor is uniform enough to offset the influence of earthquake vibration on the stability of the shooting picture.

It is worth mentioning that vivo has also customized a brand-new IMX598 sensor for X50 Pro's micro-pan/tilt lens, and it is equipped with a large aperture of f/ 1.6, and its photosensitive performance is better than the mainstream f/ 1.8. In addition, the stronger anti-shake ability of the micro-pan/tilt structure allows the camera APP to get a longer exposure time when taking pictures. X50 Pro can also trigger the extreme night algorithm in low light environment, and use the AI denoising algorithm in the RAW domain to take clear and less noisy photos. According to the data provided by vivo laboratory, the anti-shake ability of micro-pan/tilt in dark light is 12.5 times that of non-optical anti-shake, which is twice that of ordinary optical anti-shake in dark light.

In addition to the miniature pan/tilt camera, vivo X50 Pro is also equipped with an 8 megapixel wide-angle macro lens (supporting 120 ultra-wide angle and 2.5cm ultra-macro),1300,000 pixel portrait lens (50mm focal length, equivalent to 2 times optical zoom) and an 8 megapixel periscope telephoto lens (equivalent to 5X optical zoom), which can support up to 60 times digital zoom and zoom.

Rich shooting function

Motion tracking and anti-shake auxiliary settings, the former can ensure that the subject is always in focus, and the latter can display a checkpoint in the viewfinder to visually display the tilt angle of the mobile phone.

Super anti-shake will lose some edge images. If you want to record more content, you can choose super wide-angle video.

Stunning screen and fashionable design

Vivo X50 Pro uses a hyperbolic screen made of 6.56-inch AMOLED. Thanks to the new generation of luminescent materials, this screen has an ultra-high contrast ratio of 6 million: 1, a color saturation of 103% NTSC, a wide color gamut of DCI-P3, a local peak brightness of 1 300 nit, and also supports HDR 10+.

The screen of vivo X50 Pro also supports a refresh rate of 90Hz and a sampling rate of 180Hz. The former can make the screen display smoother, while the latter can make the operation easier. The combination of the two can give people a feeling of "not going after use".

In order to maximize the potential of this 90Hz screen in video playback, vivo cooperated with Tencent Video, iQiyi and Youku to create a high-frame ultra-clear video zone. In addition to providing users with 286 high-frame high-definition videos, we also repaired11classic movies with the above three companies to improve the clarity and fluency.

Vivo X50 Pro continues the extreme screen design of X30 series, but this time, the opening of the front camera is placed in the upper left corner of the screen, and the ultra-small aperture combined with the narrower screen frame, its screen ratio parameter reaches an ultra-high 92.6%, almost full screen.

The back cover of vivo X50 Pro still adopts 3D curved surface design, and the curved surfaces on both sides are just right, which makes it feel excellent when held. This product provides two fashionable colors of black mirror and liquid oxygen, and introduces a brand-new AG matte process, which brings a delicate and soft touch and presents a calm and hazy visual experience.

Compared with the common 5G mobile phones on the market, vivo X50 Pro also has an inherent advantage, that is, it is very light and thin. The thickness of 8.04MM and the weight of 1.8 1. g are relatively light in front of a group of competing products of about 200g, and even if MM users use them for a long time, they will not feel obvious drop.

Mainstream level performance

Vivo X50 Pro is equipped with Qualcomm Snapdragon 765G mobile platform, supports NSA+SA dual-mode 5G networking, and covers common 5G frequency bands such as N 1, N3, N4 1, N77, N78 and N79. The combination of intelligent network switching, dual WLAN network acceleration, data network acceleration, system intelligent power management and network power optimization functions makes vivo X50 Pro more power-saving while networking at high speed.

Vivo X50 Pro comes standard with 8GB LPDDR4X memory, and there are flash versions of 128GB or 256GB UFS2. 1. 400 yuan. Considering that this product does not support memory cards, and the Yuntai HD ultra-stable camera that vivo X50 Pro is best at is "big", I suggest you choose the high-end version of 8GB+256GB first. If you choose 128GB, you can use the cloud service of vivo members to save some photos and videos in the cloud, saving the storage space inside the mobile phone.

Snapdragon 765G is a high-end 5G SoC, which adopts 7nm EUV technology more advanced than Snapdragon 865, and integrates Qualcomm's second generation 5G baseband Snapdragon X52 and supporting RF system. Its CPU adopts a three-cluster architecture of 1+ 1+6, including 2.4GHz 1 very large core, 2.2GHz 1 performance core and 6-efficiency core of 1.8GHz. Meanwhile, Snapdragon 765 also integrates Adobe 620 GPU and Spectra 355 ISP.

Compared with the flagship 5G SoC such as Snapdragon 865, the performance of Snapdragon 765G is definitely not enough, but it is not a problem to run games such as the glory of the king and Peace Elite at a speed close to that of Quan Huafu, which is enough for most children's shoes.

Vivo X50 Pro comes standard with 43 15mAh battery, supports 33W flash charging technology, and can charge 57% power in 30 minutes. If you have higher requirements on performance and charging power, you can consider vivo X50 Pro+ equipped with Snapdragon 865 mobile platform, which also supports faster 44W flash charging and has more perfect comprehensive performance.

By the way, vivo X50 Pro and X50 Pro+ also integrated independent AK4377A and CS43 13 1 audio decoding chips respectively, and passed the Hi-Res certification. Both of them can achieve Hi-Fi performance in sound playback, leaving no regrets in audio-visual entertainment.

summary

Pursuing more perfect imaging capability is the current trend of high-end 5G mobile phones, such as relying on periscope telephoto lens to break through the field of vision, relying on more perfect anti-shake technology to achieve more professional hand-held photography, and must also achieve "people have me, people have me".

Vivo X50 Pro is such a "superior" new product. Just when other competing products are still in the era of EIS electronic anti-shake, OIS optical anti-shake or EIS+OIS hybrid anti-shake, this product has launched an innovative miniature pan/tilt super-sensitive lens, which has pushed the anti-shake ability of mobile phones to a new height and created a new concept of full-focus intelligent image. If you are not particularly demanding on performance, like to record the time around you at any time through your mobile phone, and are keen to capture the wonderful moments in the dark, vivo X50 Pro will never let you down.

Also released with X50 series are vivo TWS Neo true wireless headphones. Finally, let's enjoy a set of pictures of this product:
