Is the camera performance of vivo X70 Pro+ really that strong? Evaluation of Lijiang Real Shooting Experience

In September last year, vivo released a brand-new flagship mobile phone X70 Pro+, which gained a lot of reputation after listing. For those of us who have used the previous generation X60, it is also itchy. A month ago, we got a new mobile phone, but the weather in Chongqing didn't clear up for a long time. We also flew to Yunnan for vivo X70 Pro+, and took many photos and videos during our trip to Lijiang and Shangri-La. Let's see if the image performance of this phone is really affordable.

This time, we used the most popular "wild" blue among the three colors in vivo X70 Pro+ series. The blue skin of the whole face not only echoes the small blue mark on the lens module, but also is more anti-slip and easier to hold than the glass and plastic materials used by most mobile phones at present.

Then there is the rear lens module that we value most. Previously X60 series unique cloud step was upgraded to a wide ceramic cloud window on X70 Pro+. The larger cloud window balances the visual proportion of the camera module, and the combination of ceramics, leather and metal is very sexy.

The anti-shake pan/tilt, which was proposed from X50, has also been preserved. After X60 optimization, you can see the working state of the miniature pan/tilt on X70 Pro+, and you can calibrate it manually in the background. It seems that the miniature pan/tilt may be the iconic design of vivo X series in the future.

Although the miniature pan/tilt is only equipped with a wide-angle main camera, other rear lenses have OIS optical image stabilization function. The specific parameters are as follows:

1 50 megapixel GN 1 main camera,11.3 inch CMOS, supporting dual-core focusing, equivalent focal length of about 24mm, aperture F 1.57, and supporting OIS optical image stabilization.

2. The main camera of 48-megapixel ultra-wide-angle micro-pan/tilt, 1/2 inch CMOS, the equivalent focal length is about 14mm, and the aperture is F2.2, which supports micro-pan/tilt stabilization.

3.120,000-person main camera, which is equivalent to a focal length of about 50mm and an aperture of F 1.6, and supports dual optical zoom OIS optical image stabilization.

4, 8 million pixel periscope ultra telephoto, aperture F3.4, 5 times optical zoom, up to 60 times digital zoom, support OIS optical image stabilization.

Because of physical limitations, even if the mobile phone manufacturers roll up the image function again, the CMOS of mobile phones will not continue to increase as in previous years. It can be predicted that in the next competition of manufacturers' image, mobile phone algorithms will definitely occupy a larger proportion. Therefore, this time, in addition to continuing the cooperation between the previous generation and Zeiss, vivo X70 Pro+ has also added a professional video chip V 1 which can provide functions such as frame insertion and dynamic frame rate in normal use.

In terms of image, the chip v 1 can run MEMC denoising and frame insertion with low power consumption, and cooperate with the original noise reduction function of the main chip ISP to realize secondary lighting and secondary noise reduction. Simply put, it can be shot more purely and quickly in the case of insufficient light, and it is more convenient to realize the functions of "super moon" and "night portrait".

In the theoretical test, the resolution, high-quality image and tolerance of this mobile phone are mainly tested and analyzed. Unless otherwise specified, the test is completed by default with a 50 megapixel main camera. The following is the camera module information provided by official website.

00 1 resolution test

In the resolution test, we use four rear cameras to shoot the resolution target, intercept the image quality of the center and corner, and then zoom in to see the specific image quality performance of different lenses.

All four lenses are constant aperture lenses. After passing the resolution test, we can see:

002 high sensitivity test

When you open professional mode in the camera application, you can manually adjust the exposure. The sensitivity range of vivo X70 Pro+ is ISO50~ISO3200. Taking the whole ISO as a level, the details and dark parts are cut off to see that the image quality changes with the increase of sensitivity.

As can be seen from the screenshot, when vivo X70 Pro+ is below ISO400, the details and dark parts of the picture can present a relatively pure picture.

When using ISO800, local smear will appear in the dark; By ISO 1600, many details have been missing from the flower details of the picture, but the black part of the dark part does not appear in the common color noise on other mobile phones. It can be seen that V 1 chip has a good noise suppression effect. When using vivo X70 Pro+, we suggest that the sensitivity should be controlled below ISO800 as far as possible to obtain the best picture quality.

003 tolerance test

When using vivo X70 Pro+, you can set the "professional" mode to shoot materials in jpg and Raw formats at the same time, so our test also tested the tolerance of jpg and Raw formats respectively.

We set the shutter and ISO automatic in professional mode, and only adjust the exposure compensation of the camera. The exposure compensation range of the camera is between -3EV and +3EV.

From the restored jpg format and Raw format, it can be found that the photo tolerance range of vivo X70 Pro+jpg format is between -3EV file and +2EV file in jpg format;

After using the Raw format, the photo tolerance is obviously increased, and all the details can be pulled back after 3 files of overexposure. Therefore, when taking some photos with large light ratio, it is best to keep the Raw format file at the same time for later pull-back.

004 deformation test

In the distortion test, we photographed the brick wall with four lenses and observed the distortion degree of the image. Judging from the shooting results, the distortion of the wide-angle main camera, the main camera and the portrait lens can be almost ignored, except for the slight pincushion distortion in the picture taken by the periscope telephoto lens. On the one hand, such a good distortion performance is the embodiment of lens quality, on the other hand, it is also related to the algorithm of built-in V 1 chip.

005 anti-shake test

At first glance, the video anti-shake system of vivo X70 Pro+ is more complicated. There are three modes: standard anti-shake, super anti-shake and horizon anti-shake. However, after entering the professional video interface, the anti-shake mode is simplified to on or off. The following is the opening effect of the anti-shake mode tested at 4K 60fps.

It can be seen that when the anti-shake mode is turned on, the slight tremor of the hand is filtered out a lot. For a lighter mobile phone, turning on the anti-shake mode helps us to achieve the effect of approximate stabilizer when shooting a small range of moving pictures.

Although vivo X70 Pro+ performs well in theoretical tests, it is the most important quality for consumers. Next, we will discuss the practical experience of vivo X70 Pro+ from two dimensions: photos and videos.

00 1 Zeiss

In addition to the blessing of Zeiss T* on the lens, vivo X70 Pro+ can also turn on the natural color of Zeiss inside the fuselage, making the straight color more realistic.

We also took the primary colors, Zeiss natural colors and Raw files of the same picture. From the comparison, we can see that the cold color of the primary color will give people a more gorgeous feeling, while the performance of Zeiss natural color for color is indeed more in line with the real color and the visual habits of human eyes.

In the umbrella figure below, the natural color of Zeiss is more obvious: while using the natural color of Zeiss, the algorithm will also protect the details of the dark part of the picture. It can be seen that after the dark part is forcibly promoted by using the Raw format, a purple color cast will occur in the dark part.

Therefore, when shooting in plateau areas, we usually use the natural color of Zeiss directly. While preserving the bright sky, the photos are highly saturated and full of flavor. It is really difficult for us to manually adjust the color science of Zeiss in the later stage.

002 original file

Although the natural color of Zeiss is very strong, in some environments with too large light ratio, the choice of bright and dark parts in the built-in algorithm may not be as we wish. At this time, the importance of RAW format files is shown. When there are obvious highlights in the picture, we will open the RAW format, which is convenient for modifying the light-dark relationship of the picture later.

At present, the mobile version of PS, LR and other software can directly open the RAW format. The main photo with 5000W pixels gives people an impression on a small screen, which is comparable to the high-precision picture taken by a professional camera. RAW format retains the original data of picture information to the greatest extent, giving a relatively large adjustment space. For those who are used to using professional hosts such as SLR and micro-single, the original picture generated by Zeiss natural color can also be used as a good color matching reference.

003 night scene

The shooting performance of vivo X70 Pro+ in dark environment has been greatly improved. Compared with the previous generation X60, X70 Pro+ uses the operation of the chip V 1, which has much faster processing time, better performance on the details of the night sky, and obvious noise reduction effect. There is no colorful noise in the dark, and the color of the sky is still pure.

At the same time, vivo X70 Pro+ has excellent control over ghost glare due to the improvement of Zeiss T* coating. Facing the direct light source, it will hardly produce obvious ghost effect, which can be said to be a sharp weapon for night shooting.

004 portrait mode

When portrait mode is turned on, the lens module will activate a portrait lens with a focal length of 654.38+0.2 million, and the focal length is about 50mm in Quan Huafu. In the stylization option of portrait mode, vivo X70 Pro+ still retains four Zeiss certified filters, namely Biotar, Sonnar, Planar and Distagon.

Among them, the literal translation of Biotar, that is, the legendary rotating blur, that is, the rotating focusing effect we often say, is more obvious in scenes with more background spots.

Sonner, that is, cream blur with large spots, is also one of the most popular filters in our daily life. This filter can make people more "soft" and reduce the unnaturalness of the algorithm for character edge and background segmentation.

Of course, the pixels of this lens are still not as good as the main shot, so we will also shoot directly with the film that comes with the camera. The retro halo effect will be randomly added to the photo, and with the rich effect of changing the shape of the background blur point, we can play a lot of tricks.

005 macro model

With the continuous development of vivo X series hardware, various special shooting angles can also be realized on X70 Pro+, such as "Super Macro Auto" which automatically turns on when approaching the subject.

In the photo mode, when you are close to an object, the super macro function will be automatically turned on, and then the 50-megapixel main camera will automatically switch to the 48-megapixel super wide-angle main camera. When shooting some detailed objects, the edges of the picture will be blurred appropriately, and the film will show the perspective of being in a "lilliputian country".

00 1 video shooting quality

Vivo X70 Pro+ can shoot 8k24/25/30 fps in professional mode; 4K 24/25/30/50/60fps video and 240fps slow-motion video of 1080p and 720p. I also shot a lot of 8K materials this time. When editing, 8K material can leave more space for our secondary composition.

Compared with other mobile phones, the video compression rate of vivo X70 Pro+ is higher, with 4K video at about 63Mbps and 8K video at about 1 10Mbps. Judging from the final rendering effect, vivo X70 Pro+ achieves a high compression ratio while preserving the image quality and clarity as much as possible. When shooting 4K or 8K video for a long time, you don't have to worry that the memory will be filled up quickly. When editing with post-software on mobile phones or computers, the requirements for equipment hardware can also be reduced.

002 anti-shake performance

The anti-shake performance of vivo X70 Pro+ has been clearly demonstrated in theoretical tests. Good anti-shake performance allows us to get a relatively stable and usable picture with as few stable devices as possible.

When traveling, we often use vivo X70 Pro+ to shoot the scenery outside the window. Because the ultra-wide-angle lens supports micro-pan/tilt image stabilization, and the other three are OIS optical image stabilization, we can take a very stable picture by hand even when driving on bumpy roads, which is also a big black technology developed by vivo X series so far.

Walking normally with your hands, just using the selfie stick, you can see that the vibration of the picture is offset a lot by going straight out of the picture without anti-shake. Although there is still Z-axis jitter, it is not serious.

003 professional mode

Under the professional video mode resolution of 4K 30fps, we can manually turn on the log mode, and the log mode of vivo is easier to restore. Using Alexa default logc2 rec.709 that comes with PR to restore Lut will not be too disobedient. Fine-tuning can restore highlights and shadows of the shooting scene.

In addition, video shooting in professional mode, like photo shooting, can freely adjust ISO, shutter speed and other parameters to achieve manual focusing, waveform viewing and other functions. For friends who have experience in using micro-cameras, SLR and other hosts, I suggest trying professional mode to shoot videos more, which can unlock more shooting fun.

004 smooth scaling

In camera mode, vivo X70 Pro+ I * * has four zoom anchor points, which are 0.6 times (super wide angle), 1 times, 2 times and 5 times, and the zoom is 60 times.

The four anchor points are also switching different shots, which is common in most multi-lens camera modules. However, in the process of continuous zoom shooting, many pictures will feel obvious frustration due to lens switching (especially in the process of switching from super wide-angle lens to wide-angle main camera), but vivo X70 Pro+ can firmly lock the center of the picture during zoom shooting, which makes us feel quite amazing.

005 intelligent delay

Time-lapse photography is the mode that we shoot most with vivo X70 Pro+, not for anything else, just because it is very convenient to generate 4K time-lapse video directly in the machine, and shooting time-lapse with super wide-angle main camera lens is also very suitable for all kinds of scenery we encounter along the way.

With the help of the lightweight skylark tripod, you can also shoot cool motion delays in the car. Erection anytime and anywhere-this is also one of the advantages of mobile phones. Because it is automatically generated in the machine, it will not cause repeated accumulation of materials. For a lazy person like me, it saves space and time to shoot at any time with my mobile phone when I go out.

It can be seen that the video shooting of X70 Pro+ is very comprehensive, and almost every function is designed for the later use of the material. From anti-shake to smooth zoom performance, it can be seen that vivo has absorbed many user opinions of previous generations of products.

Of course, we also found some problems in the use process, and the user interaction needs to be optimized for the video system. For example, there are two recording interfaces in the camera: video recording and professional video recording. The 8K video mode of professional video recording will show that anti-shake can be turned on, but in the 8K video mode of video recording, it will be found that anti-shake cannot be turned on.

Or when we start shooting in "video recording" mode, adjusting any one of the frame rate, resolution and anti-shake mode may cause changes in the other two, resulting in a large number of mixed videos with different resolutions when we look at the material later. Fortunately, this is not a hardware problem, but the system is updated and the prompt of the current shooting specification is added in the shooting interface.

Does the image of vivo X70 Pro+ perform well?

There is no doubt about the answer. In still photography, the natural color of Zeiss and the blessing of four lenses meet most of our shooting needs functionally. In terms of dynamic video, the anti-shake mode suitable for various occasions and the blessing of 8K video greatly increase the availability of our shooting materials.

In the process of using it, we are often amazed by its direct color and rich functions. If there is any deficiency, it may be that the integration of image functions needs to be strengthened. Although this is also a common problem in the domestic mobile phone camp at present, we also believe that vivo X series will definitely bring us a more different mobile phone image experience in the future.

Advantages:

1, the direct output color of Zeiss is excellent, and most drawings can be directly output.

2. All four lenses contain OIS optical image stabilization.

3. The shooting modes are diverse enough to cope with a variety of complex environments.

4, 50 million high-pixel image quality is excellent, and lens stacking is better than products of the same price.

5. Thanks to the chip of V 1, the noise reduction effect is good when shooting night scenes.

Disadvantages:

1. Need to integrate the functions in video mode to improve the experience.
