Speedy Performance that Captures Decisive Moments

The impressive autofocus system on the new a6400 inherits many technologies from Sony's newest cameras including the a9, a7R III and a7 III models. The new camera features 425 phase-detection AF points and 425 contrast-detection AF points that are placed densely over the entire image area, covering approximately 84% of the image area. This high-speed, high-performance-tracking AF system is paired with a new-generation BIONZ X image processing engine that together allows the camera to acquire focus in as little as 0.02 secondsii and maintain subject lock extremely effectively, ensuring even the fastest moving subjects can be tracked and captured with ease.

The a6400 introduces an advanced ‘Real-time Eye AF', the latest version of Sony's acclaimed Eye AF technology. This exciting new capability employs artificial intelligence-based object recognition to detect and process eye data in real time, resulting in improved accuracy, speed and tracking performance of Eye AF. In all autofocus modes, the camera now automatically detects the eyes of the subject and activates Eye AF with a half press of the shutter button, and when in AF-C or AF-A mode, the preferred eye (left or right) of your subject can be selected as the focus point. Choices include Auto / Right Eye / Left Eye, and a Switch Right / Left Eye function can be assigned to a custom function as well. This exciting new technology completely frees the photographer to focus solely on composition with full trust that focus will be tack sharp on the subject's eye. Eye AF support for animals will be added in Summer 2019 via a system software update, ideal for wildlife photographers.

Also debuting on the a6400 is Sony's newly developed ‘Real-time Tracking'. This mode utilises Sony's latest algorithm including Artificial Intelligence based object recognition and processes colour, subject distance (depth), pattern (brightness) as spatial information to ensure that all subjects can be captured with excellent accuracy. Plus, when photographing or videoing humans or animals, face and eye position information is recognised by AI and the subjects' eyevii is monitored in real time with extremely high tracking precision. This can be activated by a simple half press of the shutter button[viii], or can be assigned to a custom function as well.

In terms of overall shooting speeds, the new camera can shoot at up to 11 fpsiv with full AF/AE tracking while utilising the mechanical shutter, and up to 8 fpsv with full AF/AE tracking while silent shooting. It can shoot at each of these speeds for up to 116 frames JPEG Standard / 46 frames RAW compressed, greatly increasing the chances of capturing the perfect moment.

All-around Advancements in Image Quality

Sony's new a6400 is equipped with a 24.2 MPiii APS-C sized image sensor that is paired with an upgraded BIONZ X processor to deliver incredible advancements in image quality and colour reproduction in all types of shooting conditions. Standard ISO ranges up to ISO 32000 for both still and movie and is expandable up to ISO 102400 for still images, with excellent noise reduction at medium and high sensitivities.

The camera also inherits many of the image processing algorithms from Sony's newest full-frame cameras, greatly suppressing noise while preserving resolution and improving texture depiction.

Advanced High-Resolution 4K Movie Recording with Fast Hybrid Autofocus

The versatile a6400 is an exceptional video camera, offering internal 4K (QFHD: 3840 x 2160) movie recording with full pixel readout and no pixel binning to collect about 2.4x the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with exceptional detail and depth. focusing during movie shooting is fast and stable thanks to upgraded Fast Hybrid AF technology, which keeps the subject in constant smooth focus no matter the scene, and even if an object crosses in front. This advanced AF plus touch focus functionality make it an ideal camera choice for many vloggers and video creators that are regularly creating and uploading content online.

For time-lapse movie creation, the new camera features built-in interval recording that can be set anywhere between 1 and 60 seconds, with a total number of shots from 1 to 9999. AE tracking sensitivity can be adjusted to “High", “Mid" or “Low" during interval shooting, allowing for reduced changes in exposure over the shooting interval.

Additionally, for the first time in a Sony APS-C mirrorless camera, the new model includes an HLG (Hybrid Log-Gamma) picture profile, which supports an Instant HDR workflow, allowing HDR (HLG) compatible TV's to playback beautiful, true-to-life 4K HDR imagery. Furthermore, both S-Log2 and S-Log3 are available for increased colour grading flexibility, as well as Zebra functionality, Gamma Display assist and proxy recording. The camera can also record Full HD at 120 fps at up to 100 Mbps, allowing footage to be reviewed and eventually edited into 4x or 5x slow-motion video files in Full HD resolution with AF tracking.

Upgraded Build to Maximise Versatility

Product features in detail

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. speed, while High-density AF Tracking Technology follows even erratically moving subjects.

More accurate autofocus in dim lighting

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.

Easier manual focus with an 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. Works seamlessly with compatible Sony lenses.

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.

High speed continuous 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.

An innovative image-processing system

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

Extraordinary image quality, low noise and a 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.    

Newly added 1:1 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 gradation

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

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 S format, a consumer-friendly version of a format for professional use, plus HLG support result in better-looking movies.

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. 

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. 

Sophisticated features for easier movie-making

The 6400 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 camera 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.

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 EdgeTMdesktop applications. A simple variable-speed preview function allows you to see an image, on the camera, of how the finished movie will look.

180°-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-FinderTM 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. 

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.

User-interface improvements for efficient settings 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.

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.

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.

Advances in remote camera control

When doing remote shooting using the Remote app from the Imaging Edge desktop applications, you can now use the overlay display to make precise adjustments to focus and composition while checking the live view on your PC screen.

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.)
