One-inch outsole image flagship Sony micro-single mobile phone Xperia PRO-I evaluation

Sony's black card RX 100 series is highly praised by photographers for its professional control and small portability. Even under the influence of the rapid development of mobile phone camera sensors and algorithms, Sony Black Card still has an unshakable position. Recently, Sony has integrated its black card products with the Xperia series, and launched a brand-new image flagship Xperia Pro-I. While retaining the features of Xperia products, the concept of One SONY has been further developed to the extreme through the integration of hardware and technology in images.

The highlight of Xperia PRO-I, Sony China's flagship camera phone, is its 1 inch image sensor and phase detection autofocus function. In addition to achieving better shooting quality performance, it realizes eye autofocus and object tracking in video shooting. Then how is the performance of this product? Next, I will send you a detailed evaluation.

1 inch outsole sensor

The biggest upgrade of Xperia PRO-I should be the image capability. As the image flagship, Xperia PRO-I adopts a brand-new 1 inch Exmor RS stacked image sensor. This CMOS is based on the same image sensor of Sony Black Card RX 100 VII digital camera, with a unit pixel spacing of 2.4um, which has the characteristics of fast image transmission, high latitude and high resolution.

If you simply look at the parameters, Xperia PRO-I can definitely be called the flagship of the dream camera in the current smart phone category. However, in actual use, we found that this 1 inch sensor has a total pixel of 20 million, but in fact it can only output photos of 1 200,000 pixels, that is to say, Sony did not fully use the outsole of1inch, but actually the lens only covered the1/0.3-inch sensor. Considering the thickness of the fuselage and the position between the lens and the sensor, this method can better ensure the imaging quality of the edge of the picture when shooting than expanding the incident angle of light and forcibly occupying an inch of outsole.

In terms of lens used, Sony equipped this 24mm main camera with Zeiss Tiansai optical structure and T* coated optical glass lens. Compared with the resin lens currently used in mobile phones, the glass lens has better light transmission effect. The lens designed with Tiansai optical structure also provides the function of switching F2/F4 double apertures, so users can choose the appropriate aperture according to the ambient light to shoot.

The optical structure of Zeiss Tiansai is a design with simple structure and excellent imaging quality, which can only be seen in the camera lens. The biggest feature of the sky plug structure is that the imaging resolution in the center of the lens is high, but the resolution at the edge of the lens is obviously attenuated. In order to reduce the resolution attenuation of the central edge, Sony also used 1 aspheric ed lens in the lens group for correction, which not only improved the imaging quality of the lens edge, but also improved the lens distortion and dark angle problems.

From the actual photo proofs and video proofs, it can be seen that there is no obvious problem of resolution reduction when the center is corrected to the edge of the lens, and the lens distortion only appears slightly in some close-up pictures taken at close range, which will not affect the overall impression.

Of course, the outsole sensor combined with the maximum aperture of f2.0 can also take pictures in dark environment. Although there is no special night scene mode in the photographer's APP, it will automatically identify the dark environment through AI, and the exposure time can be appropriately extended by detection when taking pictures. Of course, users can also choose to shoot manually. If you want more details, you can also save the format as RAW in the settings for later modification.

Excellent fast focusing experience

Xperia PRO-I also has 3 15 phase detection autofocus points, which covers a wider range than the previous Xperia 1 series, and achieves about 90% focus coverage of the framing screen. Of course, in addition to excellent focusing function, Sony Xperia PRO-I also provides high-speed continuous shooting at 20 frames per second, AE/AF detection at 60 times per second, anti-distortion shutter, optical image stabilization of sensor displacement, multi-frame noise reduction, 12-bit RAW photos, high dynamic range and other functions. These functions can be turned on in the main photographer App. Whether taking photos or videos, users can simply get accurate and fast autofocus performance support.

The camera of Xperia PRO-I is by far the most advanced imaging and autofocus system in the whole Xperia series. Users who enter the Master Photographer APP can feel that its operation process, control interface and performance are basically the same as Sony's latest Alpha series Quan Huafu micro-camera, so friends who are familiar with Sony cameras can get started directly with zero threshold.

During this real shooting experience, Sony Xperia PRO-I still performed very well in focusing, with high object recognition accuracy, real-time tracking success rate and focusing accuracy.

For example, when shooting a person, the shooting distance is within 10 meter, and Xperia PRO-I can accurately identify the face or eyes of the person at all angles (only the human body or head is recognized when shooting in the back and long distance), and the focus can be accurately tracked in real time in AF-C focusing mode. Even if the focus object temporarily leaves the viewing screen, when it returns to the viewing screen again, it can quickly identify the focus and keep the focus.

In video shooting, when the 3.5mm standard audio interface is correctly connected with the external directional microphone (including headphones), the system of Video Master and movie master App will automatically switch the audio reception option to "external" (it cannot be turned on and off manually) and force the external directional microphone to capture video.

To sum up, Xperia PRO-I has maintained the excellent focusing performance of Sony mobile phones before, and the outsole lens has a good degree of restoration for the pictures taken. However, the algorithm of shooting in the default mode needs to be improved, and sometimes the details in the picture are lost because of too much HDR decoration. If you are a photographer or a user who often uses a Sony micro-camera, it is recommended to shoot in manual mode. By adjusting various parameters in the photographer's APP interface, Xperia PRO-I will become a more professional camera, thus achieving better shooting results.

Specifications and performance

Like many flagship smartphone products in 202 1, Sony Xperia PRO-I is also equipped with Qualcomm Snapdragon 888 mobile platform, which adopts unique three-cluster CPU architecture design and 5nm advanced technology. In the CPU part, the latest Kryo 680 architecture is applied, and a new Cortex-X 1 super core is added, with a main frequency of 2.84GHz, which improves the CPU performance of Qualcomm Snapdragon 888 by 25%. GPU architecture is Adreno 660, which improves the graphics rendering performance by 35%, allowing players to run smoothly in complex scenes of large games.

Sony has also introduced a large number of display and audio technologies into mobile games. In addition to increasing the screen refresh rate to 120Hz, Sony also introduced motion blur elimination technology up to 240Hz, which makes the dynamic game picture on the screen clearer when running compatible games. Sony even optimized the charging scene during the game. When it detects that the heat is too high, it will automatically stop charging the battery and only use the external power supply to power the mobile phone system.

In terms of system, Xperia PRO-I still adopts the cooperation scheme of native Android and third-party applications, which is very simple as a whole. app store, weather and other software directly cooperate with Meizu to transplant these applications to flyme system, but it still needs authorization every time the app is installed. Although localization has made great progress, there is still a long way to go to provide a more comfortable experience for Sony mobile phones.

Brush the screen height of 4K mobile phone.

The screen ratio of Xperia PRO-I is 2 1: 9, which is the same as the previous Xperia 1 series. The screen resolution of OLED is 3840 x 1644, which is equivalent to 643 pixels per inch, and it has the display effect of 10bit HDR. At the same time, this screen still supports the addition of 120Hz refresh rate. 4K 120Hz also makes Gensonnie the first high refresh rate screen in the industry.

The specification of this screen is undoubtedly the highest in the flagship of smart phones at present, which can provide better picture performance for users shooting 4K videos and watching HD movies. Coupled with the support of front dual speakers and Dolby panoramic sound, the full-screen picture of 2 1: 9 makes the viewing experience even better. Screen color provides main mode and video image enhancement. When watching movies, the mobile phone will automatically turn on, and the screen can also meet the different needs of professional creation and entertainment for screen color. However, this screen is slightly lacking in maximum brightness performance, and the problem of insufficient brightness is still slightly regrettable for an organic light-emitting diode screen.

Sony is committed to providing users with the perfect mobile phone screen to watch video content, and has not adopted the popular hole-digging design to increase the screen ratio. A more symmetrical border makes it better to watch the video horizontally. In the actual experience, the screen ratio of 2 1: 9 also brings more interesting gameplay to the use of mobile phones. The multi-window mode of 2 1: 9 has corresponding options directly on the home page. Default collocation or manual adjustment, multi-task start faster. At the same time, the side-by-side feeling function also allows us to find commonly used apps and settings more quickly, making it easier to hold and use with one hand.

Experience in process, design and control

Xperia PRO-I retains many features of Sony products in appearance and design, and its body workmanship is also quite fine, maintaining the excellent quality of Sony products.

The frame of Xperia PRO-I is made of metal, and its shape is still square, which is very different from the mainstream full-screen design of digging holes. The unique metal frame structure is different from the previous Xperia 1 series. The frame and corner of the fuselage are chamfered and rounded, and there are diamond-shaped teeth, which increases the grip feeling and provides stable grip feedback when taking pictures horizontally.

The hypotenuse texture of the frame visually reduces the thickness of the whole machine. On this frame, Xperia PRO-I has also added many buttons, jacks and openings, including common power switches, volume increase and decrease buttons, cardless mobile phone/memory card slots, USB-C(USB3.2 Gen 2 standard) interfaces, and 3.5mm headphone jacks and lanyards that are not common now. All buttons, jack openings and borders have waterproof and dustproof seal design.

It is worth mentioning that the 3.5mm standard audio interface of Xperia PRO-I adopts the "4-pole" jack standard, which can be connected to headphones or headsets for daily use, and can also be connected to an external directional microphone that also adopts the 4-pole jack standard, providing better audio acquisition for video recording.

In terms of buttons, Sony still retains the physical shutter button and adds a button for video recording. After long press, you can open the photographer's and video master's apps respectively, and the call-out operation is simple and fast.
