Sony Alpha a6400 Mirrorless Camera

Unleash your creative potential with high-level performance and advanced features such as AI-powered Real-time Eye AF; new, high-precision Real-time Tracking; high-speed continuous shooting and 4K HDR (HLG)[2][3] movie-shooting.

Despite its compact size and light weight, the Sony Alpha α6400 delivers speedy performance and a range of features you'd expect from a full-frame model. Whether you're taking still shots or movies, creative compositions or everyday selfie shots, you'll enjoy beautiful images that you'll want to share, on the go.

Lightning-fast AF

Reliable AF for great action shots

The camera's innovative AF quickly and reliably detects the position of the subject and then tracks the subject's motion, keeping it in sharp focus. 

• 425 phase-detection AF points: Densely distributed focus points blanket around 84% of the image area, aiding subject capture. 
• 0.02 sec[4] AF speed: The camera's Fast Hybrid AF system combines the best of phase-detection AF and contrast-detection AF. 
• Persistent tracking ability: When subjects are in motion, AF points densely positioned around the subject is activated for accurate tracking.

Fast continuous shooting with AF/AE at up to 11fps[5]

Never miss a moment of the action thanks to fast internal processing and a high-capacity buffer memory. Fire off shots at up to 11fps[5] with after-view or 8fps5 for live-view, with minimal display lag, and take up to around 116 shots in JPEG (Standard) or 46 shots in compressed RAW format in one continuous burst.[6]

Silent continuous shooting at up to 8fps[7]

When your shoot calls for absolute quiet, such as when you're photographing a live performance, silent shooting with no shutter noise allows shooting at up to 8fps[7] with AF/AE tracking, even in AF-C mode, with Real-time Eye AF or with Real-time Tracking, expanding your range of shooting options.

Real-time Eye AF, Real-time Tracking

Smart subject-tracking

Newly adopted AI-based subject recognition technology processes a vast amount of data to detect and track even rapidly moving subjects.

Sophisticated eye recognition and tracking

• Accurate eye recognition: Enhanced Real-time Eye AF[8] reliably recognises human faces and focuses precisely on a person's eyes. There's no need for special settings – just press the shutter button.
• Persistent eye tracking: When AF-C is set, Real-time Eye AF[8] maintains a stable focus on a moving subject even when part of the face is hidden, the face is backlit, or the subject is facing downwards. 
• Choose your subject's left eye or right eye: Now you can choose Left Eye, Right Eye, or Auto from the menu in advance, leaving you free to pay more attention to composition. These selections can be assigned to custom buttons, allowing you to quickly toggle between choices while mid-shoot. 

Persistent tracking for subjects on the move

• Real-time Tracking[9] reliably maintains focus: For sporting events and other situations where your subjects are moving quickly, keeping them in constant focus can make all the difference between catching an important, dramatic moment or missing it.
• A new subject-recognition algorithm holds onto moving subjects: A newly developed subject recognition algorithm processes spatial information based on colour, subject distance (depth), pattern (brightness), and face and eye information at high speed in real time.
• Seamless transitions from body to face and eye tracking: When shooting a distant person in motion, the tracking system captures the whole body, and the focus area will seamlessly change between the face and the eyes according to the condition of the subject. 
• Simply touch and track: Once Touch Tracking is set in the menu, select your subject simply by touching the monitor. For either stills or movies, the camera will begin to auto-track the subject.

Incredible image quality

Enjoy beautiful, remarkably detailed images

Thanks to the large sensor and the latest image-processing engine, you can shoot whatever you encounter in your everyday life, with beautifully crisp and clear images and natural colours, even in low-light settings.

• A 24.2 megapixel[10] sensor plus enhanced image processing engine: The APS-C sensor features copper wiring and enhanced circuit processing that aid in boosting light collection efficiency. In conjunction with the image processing engine, this helps achieve superior image resolution and more natural depiction of textures.
• Cleaner images even in dim light: Improved noise suppression has led to cleaner image quality, even in dark scenes where high-sensitivity shooting is required. The native ISO sensitivity has increased to a maximum ISO 32000 (with expanded ISO sensitivity at a maximum ISO 102400 for stills). Noise reduction is particularly effective in the frequently used medium-to-high sensitivity range.
• Natural-looking images that match what you see: Image-processing algorithms inherited from full-frame cameras have led the way to more lifelike colour reproduction. Human skin tones look more natural, and reproduction of plant colours has also been improved.

4K movies and pro-level features

Creative movie production

From full-pixel readout without pixel binning enabling high-resolution 4K movie recording to HDR (HLG)[3] and S-Log/S-Gamut[11] options and Slow & Quick Motion recording[12], the α6400 is loaded with advanced capabilities to support your movie-making creativity.

• High-resolution 4K recording: Super 35 mm format recording with 2.4x[13] oversampling results in 4K movies (QFHD: 3840 x 2160) with extraordinary image quality.
• Fast Hybrid AF for movies: Smooth, steady focus is in your control with high-performance AF tracking.
• S-Log[11] and HLG[3]: The camera provides a variety of options for picture profiles, including S-Log and HDR (HLG)[3]

Create time-lapse movies

Newly introduced interval shooting, which is continuous shooting with a pause of 1-60 seconds between still shots, can be carried out within the camera. This can then be used to create time-lapse movies[14] on a PC using the Viewer app from the Imaging EdgeTM desktop applications.

Vlog with useful features

If you're shooting vlogs, the 180-degree tiltable LCD monitor is useful for framing your own shots. For sound recording, in addition to the external microphone jack, there is also an optional XLR adapter (available separately) to facilitate the use of pro-level microphones to give you better audio quality.

Take advantage of various movie functions

Movies in slow motion (up to 5x) and quick motion (up to 60x)[12] can be recorded in the camera, without post-processing on a PC. Alternatively, 120fps high-speed shooting[2] of Full HD video can be used to create high-quality slow-motion footage in post-production. Proxy movie recording allows easier editing and previewing, and Photo Capture lets you extract stills from recorded movies.

Smart operability

A high-resolution LCD monitor with handy touch-screen functions

The 3.0-type, 180-degree tiltable LCD screen does more than just display the scene in front of you -- it gives you quick control over a number of the camera's functions, with a variety of intuitive touch operations.

• Touch Pad provides smooth focus-area selection: The Touch Pad function allows you to smoothly move the current focus position while you're looking through the viewfinder. Simply slide your finger across the monitor until you find the desired point you want to focus on.
• Touch Focus and Touch Shutter: When you want to shift the focus, even to the periphery of the frame, Touch Focus does it with a simple touch to the monitor. With Touch Shutter, you can set the focus and trip the shutter with a single touch.
• Touch Tracking turns on Real-time Tracking at any time: With the Touch Tracking function, you can simply touch the monitor to activate Real-time Tracking for either stills or movies. The camera will instantly lock onto the target subject and keep it in constant focus.

Set up your camera just the way you like

An array of customisation features, inherited from full-frame models, gives you greater flexibility and control over how your camera operates.

• Customised buttons put frequent operations at your fingertips: Each of the camera's eight keys and controls can be assigned to any of 89 functions and operations, with different operations depending on whether you're shooting still images or movies, or in replay mode. 
• My Menu and My Dial features put you in control: My Dial lets you assign frequently used functions to the control dial and control wheel for faster access when you're shooting. My Menu allows registration of up to 30 different menu items for quick access to menu items you use often.
• Visualised setup screen for customisation: On the custom settings screen, an illustration showing the camera's operable components shows you at a glance which button or switch you're assigning. When you're setting up the function menu, you can view the structure of the actual function screen. 
• Imaging Edge desktop applications[17]: Elevate your photography with the Imaging Edge desktop applications. Use “Remote” to control and monitor shooting live on your PC screen; “Viewer” to quickly preview, rate, and select photos from large image libraries; and “Edit” to develop RAW data into high-quality photos for delivery. Get the best from Sony RAW files, and manage your productions more efficiently.[18]
• Capture One for Sony[19]: Capture One Express (for Sony) is a free award-winning editing software that provides RAW development, easy management and powerful editing tools. Capture One Pro (for Sony) can be bought for even more editing tools and tethered shooting capability.
