Humanistic stack photography

Sony Xperia series mobile phones are famous for their unique 2 1: 9 scale screen and powerful and comprehensive audio-visual functions. The new generation of Xperia 1 III micro-single mobile phone has upgraded the processor, camera lens and display screen on the basis of Xperia 1 II. Sony positioned it as a "micro-single mobile phone", which shows its excellent photographic performance.

The following are its main upgrade highlights:

Xperia 1 III is 8.2mm thick and weighs only187 g. Compared with the previous generation, the weight and thickness are still well controlled on the basis of hardware upgrade.

Xperia 1 III adopts the classic 4K resolution organic light-emitting diode display, and the refresh rate is increased to 120Hz, which supports high dynamic range color expression. Whether watching photos or videos, it can bring users a more accurate and delicate visual experience.

The screen ratio design of 2 1: 9 has a good immersive experience in games, audio-visual entertainment. The ultra-wide screen can have a cinema-level effect, and it can also improve the convenience of holding and controlling the mobile phone with one hand. When you get used to this ratio, you will know how fragrant it is.

The Xperia 1 III cameras are arranged vertically, with Sony Logo in the middle of the fuselage, and the N word indicates that the machine is equipped with NFC near field communication function.

The lens arrangement order from top to bottom is 16mm super wide angle, 24mm standard lens, 3D iTOF lens and telephoto lens.

The upper left side of the fuselage is still a SIM card slot, which can be installed directly without a pin. Xperia 1 III is compatible with both SA and NSA 5G modes. But also supports dual card function.

There are volume keys, power fingerprint identification two-in-one keys, shortcut function keys and independent shutter keys on the right side of the fuselage.

In order to highlight the performance of the flagship audio-visual mobile phone, Xperia 1 III also reserved a 3.5mm standard earphone hole on the top of the fuselage to meet the users who need sound quality, and a speaker was built in the top.

At the bottom of the fuselage is a USB-C data interface, which can be used for charging and data transmission with the computer. Another speaker is built in the bottom, which can be combined with the speaker at the top to form advanced stereo sound effects. Its external sound quality is excellent and immersive. You can have a good listening experience even if you don't wear headphones, play games or watch movies.

The camera performance of Xperia 1 III has been significantly improved on the basis of the previous generation. Here I will experience it through real shooting.

Hardware introduction

It is equipped with super wide-angle, wide-angle and telephoto lenses, including four focal segments. Still familiar with Zeiss certified red T* coating blessing. But the sensor and lens are strengthened. 1. The main camera adopts11.7 inch stacked CMOS, and the maximum aperture is F 1.7. Whether it is detail preservation or noise control, large-size sensors have obvious imaging advantages. 16mm ultra-wide-angle lens is upgraded to 1/2.5-inch stacked sensor, and the wide-angle image quality is effectively guaranteed. Its telephoto lens is designed with PD periscope. Although it is a lens, it can achieve dual focal lengths of 70mm and105 mm. The hardware adopts 1/2.9-inch stacked sensor, which greatly improves the image quality of telephoto imaging.

Software introduction

Xperia 1 III not only has advanced photographic hardware, but also optimizes the software in all aspects. First of all, the system in Xperia 1 II comes with a camera App and a photographer App, which improves the operation efficiency. The camera in the system is converted into basic mode, which is very suitable for novices and ordinary people. The interface has a wealth of optional parameters, including lens focal length, flash, exposure, zoom, menu and so on.

When you click the shooting mode, you can switch between basic, automatic, P, S, M and other modes. The shooting UI will also switch to a style similar to professional micro-single.

Enter the menu main menu, and you can also change many more detailed options.

-Image quality-

Xperia 1 III has successfully achieved four-focal length shooting from 16mm ultra-wide angle to 105mm telephoto, which basically covers the most commonly used focal length range for daily shooting, highlighting the hardware advantages of "micro-single mobile phone".

First of all, let's take a look at the real shooting angles of four focal lengths:

16mm super wide angle (actual focal length 2.67mm)

24mm wide angle (actual focal length is 5. 1 1mm)

70mm telephoto (actual focal length is 10.22mm)

105mm telephoto (actual focal length is 14.50mm)

The following figure shows the actual image quality with different focal lengths:

From the actual shooting point of view, the overall imaging performance of Xperia 1 III with four focal lengths is very good. Among them, 16mm and 24mm have the best wide-angle performance. The telephoto part is extended to 105mm, which makes the mobile phone have stronger telephoto shooting ability, and it is easier to take photos of landscapes, humanities and other themes.

-Shooting shooting function-

Xperia 1 III is also equipped with zoom function, which can adjust the effect of background blur and simulate the shallow depth of field when shooting with a large aperture lens.

-Focusing performance-

Xperia 1 II is amazing for its excellent multi-point tracking and focusing, but the latest Xperia 1 III has no surprising further focusing enhancement. The focusing technology of Sony's flagship micro-camera α 1 is completely borrowed, and the real-time tracking function is added. In addition, Sony's unique human/animal eye focus will make Xperia 1 III perform better when shooting people, animals or moving targets at high speed.

Just like operating a miniature camera, Xperia 1 III can capture moving objects very accurately and reduce focusing error by using 3D iToF sensor and multi-phase focusing point on the fuselage. The following is a real-time tracking demonstration video:

Eye recognition focusing has always been the "killer" of Sony micro-single, and now this unique stunt has also been transplanted to mobile phones. When the face/eye AF on the fuselage is turned on, the camera will automatically recognize the people or animals in the picture and cover the face with a white border. When the shutter is half pressed to focus, it will turn into a small green box to lock the eyes. I have to say that this operation makes Xperia 1 III have a strong sense of photography, which is very interesting.

Xperia 1 III also has a good performance in video shooting, and the use of three-shot four-focal-length lenses can express richer picture language. The machine itself supports recording in HDR video format up to 4k 120p, simulates the movie master App of professional movie machine Cinealta V, and can shoot short films comparable to professional equipment. This software also allows users to adjust professional parameters such as resolution, code stream, focus, ISO and white balance, so that ordinary people can get addicted to movies.

When shooting video, the mobile phone also supports dual anti-shake blessing of OIS optics and EIS electronics. The stability of hand-held shooting is greatly improved, and ordinary people can easily record Vlog short films without additional stabilizers.

Please look at the picture comparison when the switch is anti-shake:

After turning on anti-shake, the up-and-down jitter of the picture caused by walking is obviously weakened, and it is no problem to shoot while walking.

Under video recording, the mobile phone can also start eye recognition and tracking focusing functions, making it easier to shoot interesting short films of daily life.

Video sample

First of all, the score on the latest version of Ann Bunny testing software is 769747. As the latest top-level processor in Snapdragon, this performance is good, about 200,000 higher than the previous generation processor.

According to Geekbench, another test software, Xperia 1 III also performs well in both single-core performance and multi-core performance.

Running score proves that the performance of Xperia 1 III is obviously improved compared with the old model. When playing the mainstream the glory of the king game, the author turns on the high frame rate mode and chooses the highest picture quality for testing. It can be seen that the frame rate of the game screen can be maintained at around 59FPS, and the whole game is very smooth without any jams.

I also ran another popular game-Shen Yuan, in which the picture quality was adjusted to super high and the frame rate was set to 60fps. Although this adjustment will increase the power consumption and heat generation of the mobile phone, the overall fluency of the game has not decreased significantly, because Sony hardware has designed heat-dissipating graphite sheets on both sides of the motherboard, coupled with the operation of the energy-saving and excellent performance app, which actively intercepts potential unnecessary power consumption in the background. Please enjoy the demonstration recorded with the screen recording function of the mobile phone:
