Sony APS-C format micro-single A6400
The autofocus system of Sony A6400 inherits many technologies of Sony Quan Huafu micro-cameras A9, A7RM3 and A7M3. A6400 has 425 phase detection autofocus points and 425 contrast detection autofocus points, covering about 84% of the visible area. The combination of the camera's high-speed and high-performance tracking autofocus system and a new generation of BIONZ X image processor enables the camera to achieve a fast focusing ability of up to 0.02 seconds, effectively and continuously lock the shooting object, and even the high-speed moving object can easily realize real-time tracking shooting.

In terms of focusing performance, A6400 has also been upgraded for some functions of previous models, supporting real-time eye movement AF. As an upgraded version of Sony's eye autofocus technology, this function uses artificial intelligence to detect and process eye information data in real time, which improves the accuracy of eye autofocus and further improves the focusing speed and tracking performance. In addition, the "real-time tracking" function has been added. By using special object recognition algorithm, color, distance (depth of field) and pattern (brightness) are regarded as spatial information, and artificial intelligence information including face and eyes can be used to track objects more accurately. When shooting, just press the shutter half to activate this function, or you can set a custom button to start it.

The A6400 is also excellent in video, supporting video recording with 4K (QHD: 3840x2 160) resolution. In addition, A6400 is Sony's first APS-C format micro-sheet that supports HLG (mixed logarithmic gamma) image profile. A6400 also supports real-time HDR workflow and 4K HDR(HLG) video recording, which can play more realistic 4K HDR images on Sony TV compatible with HDR(HLG). In addition, S-Log2 and S-Log3 can improve tolerance and color space, and support gamma auxiliary display, enhanced zebra crossing function and proxy recording.

Sony A6400 adopts APS-C CMOS sensor, about 24.2 million effective pixels, a new generation of BIONZ X image processor, supports ISO 100-ISO 32000, and can be extended to ISO 102400 in still photo mode. At the same time, A6400 also supports 4K video recording function, 4K HDR(HLG) video recording and S-Log2 and S-Log3.
Sony A6400 pop-up flash
Sony A6400 has a built-in small pop-up flash, which can still help you when you need to illuminate the subject indoors or in a backlight environment.
Sony A6400 electronic viewfinder
A6400 has a 2.36 million pixel XGA organic light-emitting diode true viewfinder with higher contrast and resolution. Can provide perceptual picture details and high-quality color presentation in low light environment.
Sony A6400 display screen
A6300 is equipped with a 3.0-inch LCD screen with about 920,000 pixels, which can be flipped at 180 degrees. This is Sony's first micro-display with 180 degree flip display. The LCD screen can be tilted up by about 180 degrees and down by about 74 degrees, making it easy to take selfies whether it's still shooting or dynamic video shooting. At the same time, the LCD screen also supports the touch function. In the Function of Touch Operation menu, you can select Touch Shutter, Touch Focus and the new Touch Tracking function, and you can quickly activate Real-time Tracking through the touch screen.

Sony A6400 fuselage interface
The external interface on the right side of A6400 fuselage includes Micro USB interface, charging indicator light, Micro HDMI interface and external microphone jack. At the same time, the Micro USB interface supports the charging function, which is convenient for users to charge the camera at any time and prolong the service life.
Sony A6400 memory card slot
As for the memory card, A6400 not only supports the common SD memory card /SDHC memory card /SDXC(UHS-I) memory card, but also supports Sony's own memory stick.
Sony A6400 battery
The A6400 still uses NP-FW50 1080mAh lithium battery as power supply. The endurance is slightly higher than that of A6300, and it can shoot about 4 10 at most.
Continuous shooting test
Sony A6400 continuous shooting has excellent speed. When using the mechanical shutter and the silent shutter, you can capture 1 1 sheet and 8 sheets per second respectively. Through the 4D focusing system, you can quickly, smoothly and accurately capture the moments of high-speed moving objects, and solidify the wonderful in high-quality pictures. With the help of the new BIONZ X image processor, the autofocus speed is about 0.02s s. ..
1 1 sheet/second continuous shooting presentation.
As an important part of continuous shooting, A6400 has the strongest autofocus system in Sony APS-C frame. The hybrid autofocus system consisting of 425 phase detection focuses and 425 contrast detection focuses can cover about 84% of the framing range, and can easily and accurately capture the objects entering the framing screen. At the same time, continuous shooting can start AF-C mode, real-time eye autofocus or real-time tracking, which greatly expands your shooting options.

In terms of the number of continuous shooting, A6400 can meet the standard of continuous shooting 1 16 JPEG or 46 compressed RAW photos at a time, which greatly improves the success rate of shooting wonderful moments.
4K video
In terms of video shooting, Sony A6400 is powerful. In addition to internal recording of 4K video, it also supports 4K HDR(HLG) video recording, S-Log2 and S-Log3, supports gamma auxiliary display, and enhances zebra crossing function and proxy recording. It can be said that A6400 is theNo. 1 number of Sony APS-C format micro camera in video shooting.
Oversampled 4K video
In shooting, A6400 oversamples a large amount of source information at a speed of about 2.4 times that of 4K resolution pixels by reading all pixels without pixel merging, so as to generate high-quality 4K video with excellent details and depth. At the same time, through the upgraded high-speed hybrid autofocus technology, the camera can focus quickly and stably during shooting. No matter what the scene is, you can always stay in focus even if the shooting targets overlap and stagger in front.
Built-in interval shooting function can generate delayed video.
In addition, the A6400 also has a built-in interval shooting function. The shooting interval can be set between 1 and 60 seconds, and the total shooting times can be selected between 1 and 9999. During interval shooting, the AE tracking sensitivity can be adjusted to "high", "medium" or "low", thus reducing the exposure variation during the shooting interval. After that, the latest versions of Imaging Edge Intelligent Image Application Center (version 1.40) and PlayMemories Home Desktop Application can generate delayed videos. At the same time, A6400 also supports auto-tracking focusing mode, recording full HD video at 120fps 100 Mbps, which can be edited into 4 times or 5 times slow-motion video files later.
Sensitivity test
Sony A6400 adopts APS-C CMOS sensor, and its effective pixel is about 24.2. It is a new generation BIONZ X image processor. The original sensitivity can be extended from ISO 100-32000 to ISO 102400. Let's look at the actual sensitivity performance.

Sony A6400 sensitivity test bench
As can be seen from the test pictures, Sony A6400 can keep a relatively clean picture within the scope of ISO 3200, and the details are basically intact. In terms of noise, obvious noise visible to human eyes appeared from ISO 6400 until ISO 12800 began to increase noise, details began to be lost, and the sense of smear gradually increased. Therefore, in practical application, we can use any sensitivity below IS0 3200 with peace of mind.

Edit abstract
As the first APS-C format micro-sheet released by Sony in recent two years, A6400 is not a new flagship, but its overall function is better than the flagship. Except that it does not support 5-axis anti-shake, most of its functions and performance exceed the flagship A6500 in APS-C format. Moreover, you can easily find that many new functions of A6400 are designed to meet and facilitate daily shooting of Vlog by VLOG, and its video shooting performance can be said to be the most powerful among APS-C format micro cameras at present. A6400 supports all the video shooting functions you can think of, such as oversampling 4K shooting, HLG, S-Log2, S-Log3, interval shooting, slow-motion video and proxy recording. In addition to video shooting, A6400 also has excellent static shooting ability and image quality with the new generation of BIONZ X image processor. Therefore, this is a home micro-camera that is very suitable for both useless video and still shooting.
