A new breakthrough in image experience Sony Xperia 1 IV evaluation

In the past few years, the camera function of smart phones has developed very rapidly. With the application of a series of advanced technologies such as pixels, image sensors, autofocus and imaging algorithms, the competition of mobile phone images has also entered a white-hot stage. In such a big environment, there is still a manufacturer named Sony who still insists on his own ideas and has made a "alternative" camera flagship with a breakthrough selling point-Xperia1IV.

As the flagship of Sony's new generation of mobile phone technology, Xperia 1 IV inherits many cutting-edge technologies in different fields such as Sony micro-single, TV and audio, and continues to empower products with the concept of One SONY, bringing a better comprehensive experience to video creators, music lovers, film lovers and gamers. Among them, the high-speed three-camera system is equipped with the world's first 85- 125mm mobile optical zoom lens, and with faster focusing and continuous shooting, the shooting experience based on Sony mobile phone's pursuit of "speed" is brought to the extreme.

The imaging capability of the first optical zoom lens is upgraded again.

Sony Xperia 1 IV contains many new functions and improvements, and the camera has been greatly upgraded on the basis of the previous generation. It is equipped with a telephoto lens that can realize continuous optical zoom, and all three lenses have realized 4K 120PS HDR video recording.

The Xperia 1 IV is equipped with three rear cameras, and each camera is upgraded with the Sony Exmor RS image sensor. The main camera is equipped with 24 mm equivalent focal length lens, aperture F 1.7 and optical anti-shake FlawlessEye? Technology, 1/2.5 inch sensor, super wide angle 16mm focal length, F2.2 aperture. Finally, the world's first 85- 125mm optical zoom lens, with variable aperture F2.3-2.8, 1/3.5 inches, adopts optical anti-shake FlawlessEye? Technology, zoom adopts periscope design to provide real optical zoom within its range.

Based on the previous generation of Xperia 1 III, the three-shot four-focal-segment imaging system extends the focal length of optical zoom to 125mm, which can still maintain high resolution and accurate focusing speed when switching focal lengths, and make the composition more flexible when shooting.

Functionally, Xperia 1 IV provides real-time eye autofocus and real-time tracking for still photos and video shooting. Through the 3D iToF sensor on the back, the distance of the object can be detected faster and tracked quickly. In addition to faster focusing, Xperia 1 IV can shoot full-resolution images at a speed of up to 20 frames per second and use 60 AF/AE times per second on all three rear cameras. Each lens is painted with Zeiss T*, which can generate clear images and minimize the influence of light reflection on the lens.

When shooting, Sony combines artificial intelligence technology with automatic white balance system to improve color accuracy and rendering effect. In the actual shot proofs, we can see very restored proofs, and strive to present the colors and details as much as possible. Different from the common post-retouching proofs of mobile phones, Sony rarely brings some rich color retouching. Although it is not so gorgeous in appearance, it also provides more space for later modification. If it is saved in RAW format during shooting, it can further adjust the photos to the style you want.

In terms of video shooting, each lens of Sony Xperia 1 IV can record native 4K video at a speed of up to 120 frames per second. Thanks to the excellent ISP of Qualcomm Snapdragon Mobile Platform and Sony's technical accumulation in imaging, each lens sensor can realize multi-frame HDR, that is, combine continuous frames with different brightness levels to produce a wider dynamic range video. The video is saved in HDR format, using wide color gamut and HLG coding. This means that the video will have a wide dynamic range output when viewed on the mobile phone itself or on the HDR display.

Another important new function of Xperia 1 IV is live broadcast through the Videography Pro application. This function undoubtedly provides a very convenient solution for the rapid development of short video and live broadcast demand. When in use, the video stream can be transmitted to the video platform or other services through the mobile phone without connecting other accessories or devices. If the user has a Sony Alpha camera compatible with Xperia 1 IV, it can be directly connected to the mobile phone and used as a 4K display and live broadcast device. Through simple matching connection, a more advanced live broadcast effect can be achieved.

(4K 120 frames of video material can be cut and played slowly at will, and there is more room for later editing and modification. )

appearance design

In the past several generations of product updates, the design of Xperia 1 series mobile phones has also maintained a distinctive style. This time, Sony Xperia 1 IV has also made many adjustments and modifications to its appearance, and its more square design style also has many shadows of the previous Z series.

In terms of appearance, Xperia 1 IV is completely different from most mobile phones on the market in design, and continues Sony's unique screen with a ratio of 2 1:9. Slim body proportion makes it easier to hold. Compared with 2.5D curved surface, Xperia 1 IV is flat, tough and simple, and returns to the flat design style of previous Z series. Although the tough style is a bit awkward, the narrow body size and the weight of only about 185g still keep the overall feel in a more comfortable range.

The fuselage is equipped with 4K HDR organic light emitting diode 120Hz screen, and the highest peak brightness is increased by about 50% compared with the previous one, which also greatly improves the perception of the screen that users criticize as not bright enough. The peak brightness of 1000nit can be clearly seen even in sunny outdoor environment.

6.5-inch organic light-emitting diode display screen with a resolution of 4K refresh rate 120Hz and an aspect ratio of 2 1:9. This slender movie scale screen provides a full-screen viewing experience with no black edges above and below. The peak brightness of 4K resolution of 1000nit is a better experience to enhance the delicate impression of the screen. In terms of entertainment, it is not only the ultra-high refresh of 120Hz, but also the touch sampling rate of 240Hz, which is very helpful for the game entertainment experience.

Thanks to the X 1 mobile engine technology of Sony's own TV, Xperia 1 IV continues to apply BRAVIA HDR repair technology to video content, which can improve the contrast of the whole video even when watching streaming media content. With the help of real-time HDR driving function, even in bright viewing environment, by analyzing the brightness and color of each frame, the details of bright and dark areas in the video are optimized, so as to present a scene close to reality.

In terms of audio, Xperia 1 IV adopts a brand-new speaker driving unit and a brand-new shell structure, which improves the volume and bass performance. The playback effect is more stereoscopic and the sound quality is better than the previous generation. Xperia 1 IV retains a 3.5mm headphone jack, which can directly play audio with external headphones, and at the same time improve the stereo sound effect to 360 live sound effect, and support Dolby ATMOS and Hi-Res high-resolution sound source playback of Dolby panoramic sound. Users can enjoy well-balanced stereo sound effects at any time through stereo speakers or headphones.

Further create localization function

Since Sony and Meizu reached a cooperation on 202 1 and 10, the upgrade of Xperia series mobile phones in localization experience has been recognized by the majority of users. The newly released Xperia 1 IV also provides a more complete system upgrade to better meet the localization needs of Xperia users.

This system upgrade, on the basis of keeping close to the native Android system, Sony further supplemented the localization experience of mobile phones. Xperia 1 IV is pre-installed with Flyme to adapt to Flyme's application store, email, weather and news information. It is also the first time that Flyme has joined the cooperation with negative screen, gallery, information, voice assistant and security center of Xperia 1 IV.

The biggest upgrade of Sony Xperia 1 IV system is the increase of negative screen information display, which provides a variety of quick entrances such as information search, scanning, payment code, express tracking, to-do items, repayment and payment. Embedded Flyme SMS APP can automatically classify notification SMS and personal SMS, and also automatically extract SMS verification, which is convenient for users to use in daily life. The security center allows Xperia users to filter spam messages and phone calls more easily and quickly, and can also provide remote location assistance when they can't find their mobile phones.

Although these localization upgrades have already been applied in domestic mobile phones, they can still be said to be a great progress for Sony. Xperia 1 IV system is based on the brand-new Android 12 native Android system, which provides a wealth of Flyme application adaptation blessing, which is more suitable for domestic users' usage habits and brings a leap in experience for daily use.

Flagship configuration battery capacity upgrade

Xperia 1 IV is equipped with Qualcomm Snapdragon 8 Gen 1 mobile platform, which is also the 8-series flagship platform launched by Qualcomm in the first half of this year. It can be said that it is the standard of Android flagship at present, and it supports both 5G and Wi-Fi 6, which provides performance guarantee for the use of the whole machine. In order to match the higher performance and power consumption of the whole machine, Sony has not upgraded the 5000 mAh large-capacity battery before Xperia 1 IV. If you charge quickly, you can charge about 50% of the electricity in 30 minutes. This battery supports overcharge protection, Qi wireless charging and reverse wireless charging.

abstract

Generally speaking, Sony Xperia 1 IV still maintains Sony's characteristics in image and design, and the variable optical zoom lens and full-lens 4K 120 frame video recording function are industry-leading. The screen, speakers, core performance and battery have all been upgraded to a certain extent, maintaining the performance of the flagship mobile phone and providing a better experience.

Even so, Sony Xperia 1 IV is quite different from the products in the mainstream mobile phone market in terms of design and function. While pursuing parameters and configuration, it always has its own insistence, such as its traditional 4K screen, more restored camera adjustment method, rectangular design of upper and lower foreheads, and 3.5mm headphone jack. And this persistence, let us see more new possibilities of mobile phone photography.
