Stable, fast, versatile, and compact, the Alpha a6400 from Sony is an APS-C-format mirrorless camera that adopts many of the features normally reserved for their full-frame lineup. This includes an autofocus acquisition of 0.02 seconds, Real-time Eye AF and Real-time Tracking capabilities, high-speed shooting up to 11 fps and silent shooting up to 8 fps, both with AF/AE tracking, an upgraded BIONZ X image processing engine, an LCD touchscreen that tilts 180° up and 74° down, UHD 4K movie recording with full pixel readout and no pixel binning, internal recording for time-lapse videos, and more.

The a6400 is well-suited for both photo and video creators, ranging from professionals to vloggers. Revolving around a 24.2MP Exmor CMOS sensor and BIONZ X image processor, clean image quality is provided with a wide expandable sensitivity range of ISO 100 to 102400, along with accelerated readout speeds for internal 4K24 and Full HD 1080p120 video recording with full pixel readout. The processor further benefits videographers with the inclusion of an S&Q (Slow & Quick) Motion setting that permits capturing Full HD video at a variety of frame rates ranging from 1-120 fps, plus HLG (Hybrid Log-Gamma), which supports HDR workflows, and both S-Log2 and S-Log3 for color grading flexibility. Stills shooters also benefit from the processing speed, which enables continuous shooting at 11 fps for up to 116 JPEGs, 46 raw images, or 44 raw and JPEG frames in a burst, as well as 14-bit raw file output. The sensor and processor combination also avail 4D FOCUS, with a wide-coverage 425-point phase-detection system that covers around 84% of the image area, and a 425-point contrast-detection system, both of which provide quick and precise focusing performance. This focusing system also enables Real-time Eye AF, which delivers improved accuracy, speed, and tracking performance of Eye AF, so the eyes of your subject are automatically detected. Furthermore, Real-time Tracking uses AI-based object recognition and processes color, subject distance (depth), and pattern (brightness) as spatial information to ensure that all subjects can be captured with accuracy. Increasingly versatile and fully featured in both photo and video realms, the a6400 is a fast and precise imaging tool for multimedia capture.

Complementing the imaging assets, the a6400 sports a robust magnesium-alloy body with sealed buttons and dials to help keep out dust and moisture, plus anti-dust functionality that protects the optical filter. The compact profile incorporates a high-resolution XGA Tru-Finder 2.36m-dot OLED electronic viewfinder for bright, clear, eye-level viewing, and this EVF features a 120 fps viewing mode for smooth tracking of fast-moving subjects. A rear 3.0" 921.6k-dot touchscreen TFT LCD monitor is also available and tilts 180° up and 74° down to benefit shooting from high and low working angles. The touchscreen design also allows for intuitive touch-to-focus control. Additionally, for wireless remote control over the camera, or for just sharing imagery online, built-in Wi-Fi with NFC permits linking with a mobile device for intuitive wireless control.

Unparalleled AF performance is the key to beautiful shots
Fast and accurate autofocus lets you capture fleeting moments in stunning detail, thanks to a combination of innovative technologies. A total of 425 phase-detection AF points work in conjunction with contrast-detection AF to achieve a remarkable 0.02 sec.¹¹ speed, while High-density AF Tracking Technology follows even erratically moving subjects.



More accurate autofocus in dim Lightning
Highly accurate autofocus is now possible even in dark settings, thanks to advances in the AF algorithm. With this model, the lower limit on the AF detection brightness range has been reduced to EV-2 when in AF-S mode.

AF in Focus Magnifier for finer focus adjustment
When extra-accurate autofocus is called for, such as when you're taking macro shots, you can display a magnified view of the general area you want to focus on, then finely adjust the exact point of focus in the viewfinder or on the LCD screen.

Enhanced Real-time Eye AF Supports Portrait shooting
Real-time Eye AF detects and autofocuses on the eyes of your subjects when you half-press the shutter. Either the left eye, the right eye, or auto can be specified, and when AF-C is set it maintains a stable focus even when part of the face is hidden, the face is backlit or the subject is facing downwards.

Easier manuel focus with improved peaking function
The camera's peaking function colour-highlights the most sharply focused section of the entire image area when you're using manual focus. Now blue has been added to the display's other peaking colours (red, yellow and white) to improve the visibility of the focus peak areas when you're doing the delicate focusing required for macro or portrait shooting.

Real Time Tracking holds the focus on tracked Subjects
When you're tracking a fast-moving subject, the camera's improved automatic subject motion tracker uses a newly developed subject recognition algorithm that draws on colour, pattern (brightness), subject distance (depth) and face/eye information to recognise, and hold onto, your subject.

Extraordinary image quality,low noise and wider ISO range
Maximum standard ISO sensitivity has been increased to ISO 32000 (expanded to ISO 102400 for stills), while improved imaging algorithms, detail reproduction technology and area-division noise reduction result in more realistic textures, better detail in shadow regions, and more lifelike colours, including human skin tones and natural plant colours.   

An Innovative image-processing system
The camera's APS-C size, 24.2-megapixel Exmor^TM CMOS sensor provides a wide sensitivity range and excellent low-noise performance. In conjunction with the new-generation BIONZ X^TM image processing engine, it delivers beautiful, high-resolution images with superb image clarity and texture reproduction.

High speed continues shooting with AF/AE tracking
Capture all the action with continuous shooting at up to 11fps (with after view), or 8fps (with silent shutter) and 8fps (for live view). Display lag has been minimised, and up to 116 JPEG (Standard) images can be shot, with group display available. Camera operability and access to various features while writing data have also been greatly improved.

4K movie recording in high-bit-rate XAVC S Format
Super 35mm format, 4K movie recording with full pixel readout and no pixel binning allows oversampling with approx. 2.4x as much information as is required for 4K (QFHD: 3840 x 2160), adding up to the equivalent of 6K and giving these images more realistic depth. High-bit-rate (max. 100Mbps) XAVC Sformat, a consumer-friendly version of a format for professional use, plus HLG support result in better-looking movies.

Newly added !:! aspect ratio for easier social-media shots
In addition to 3:2 and 16:9 aspect (width-to-height) ratios, the 1:1 aspect ratio used by social media platforms is now offered as an option. This eliminates the need for cumbersome hand-trimming of images after shooting in preparation for posting on social media.

14-bit RAW output with rich tonal gradiation
When you're shooting in RAW format, the 14-bit digital signals that are converted from analog in the image sensor are passed to the front-end LSI and BIONZ X, where they undergo 16-bit processing before converting back to 14-bit RAW image output. This leads to smoother, more natural tonal gradation in these images.  [1] Image Sensor  [2] The latest high-speed front-end LSI  [3] 16-bit Image processing.

Slow and Quick motion, and high-speed 120fps recording
Slow motion (up to 5x) and quick motion (up to 60x) can be recorded in camera in high-quality Full HD, and no PC-based post-processing is required to view your slow-motion and quick-motion footage. Additionally, high bit-rate recordings of up to 100Mbps in Full HD can be used to create high-image-quality slow-motion movies in post-production.

Steady, precise AF tracking for better movies
Fast Hybrid AF brings high speed, accuracy and tracking performance to meet the stringent autofocus demands of 4K movies. AF tracking sensitivity can be adjusted for either stable focus or responsive refocusing, depending on the nature of the scene, and Touch Tracking lets you initiate tracking of a moving subject simply by touching the LCD screen.

S-Gamut/S-Log shooting
S-Log shooting gives you flexibility to make more expressive movies by performing colour grading in post-production. The S-Log3 and S-Log2 gamma curves feature a wide dynamic range (up to 1300%) that can help minimise blown highlights and blocked shadows. The S-Log3 gamma setting also provides an impressive 14-stop latitude.

Interval shooting for the creation of time-lapse movies
Continuous shooting with a set interval between 1 and 60 seconds is now available within the camera, and the resulting still images can be edited into a time-lapse movie on a PC using the Viewer application from the Imaging Edge^TM desktop applications. A simple variable-speed preview function allows you to see an image, on the camera, of how the finished movie will look.

Sophisticated features for easier movie-making
The α6400 facilitates the workflow of professional videographers with a wide range of functions, including clean HDMI output, time code / user bits (TC/UB), rec. control, marker display/setting, zebra function, Slow & Quick Motion, simultaneous proxy movie recording, extraction and separate storage of a still from a movie, Gamma Display Assist function, and in-monitor display of current ISO value when shooting with ISO Auto, among others.

Support for professional-quality mic and audio input
External microphones can be attached via the microphone jack, and there is also an option for line input via XLR connectors using the camera's separately available XLR adaptor kit, which enables connection with various high-end microphones for professional-level audio.

Custom functions for greater operability
The camera's eight keys and controls can be custom-assigned to any of 89 shooting and replay functions, and frequently used functions can also be assigned to the control dial and control wheel with My Dial. My Menu allows flexible assignment of 30 menu items, and the custom settings screen helps keep track of everything. Help displays are available on the menu screen via a single button.

180º-tiltable LCD screen with versatile touch functions
The high-resolution 921k-dot LCD has a 3.0-type screen and tilts upward a full 180° for easy framing of self-portraits and vlogs. The LCD's intuitive touch operations include Touch Pad (smoothly move the focus point), Touch Focus (set the focus point), Touch Shutter (release the shutter), and Touch Tracking (activate Real-Time AF).

Smooth display on the OLED viewfinder
The high-contrast, high-resolution XGA OLED Tru-Finder^TM provides high visibility, fine details even in dark areas, accurate colours and smooth displays at either 60fps or 120fps, with the framerate selectable for smoother viewing. Standard and High quality settings are available for both the viewfinder and the LCD monitor.

More versatile flash functions
When shooting with compatible wireless flash units, rear-curtain sync and slow sync can now be selected, increasing your creative options for lighting.

User-interface improvements for efficient setting control
A new feature displays frequently used ISO ranges on the ISO setting screen, and another displays frequently used focus-area types on the AF area-setting screen. And when using Flexible Spot mode you can now cycle the AF area up, down, right and left – useful when shooting sporting scenes where the subject moves frequently within the AF area.

Greater control over white balance settings
If set in advance, auto white balance can now be locked or unlocked at any time, for more consistent colour tones when there are multiple light sources. Custom setting of white balance has been simplified, and you can now select an AWB priority setting when shooting with incandescent lighting – either warmer Atmosphere Priority, or White Priority for purer whites.

Easier ratings and protection from deletion
Still images can be given a rating or protected from deletion, and both functions can be accessed via pre-assigned custom keys.

One Touch remote, One-touch sharing, Location Information Link
The One-touch remote feature turns your mobile device into a viewfinder and remote control, while One-touch sharing allows photos and videos to be transferred to your device for social media sharing. The camera can also acquire location data via Bluetooth®. (These mobile device features are available via Sony's Imaging Edge Mobile app.)

Sturdy,durable construction for robust operation
The camera's low-vibration shutter mechanism is designed and tested to withstand around 200,000 shutter cycles, and the body, top cover and front cover use a light but highly rigid magnesium alloy. Major buttons and dials are sealed, and casing components have an interlocked double-layer structure to resist dust and moisture.
