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) movie-shooting.
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.
Fast continuous shooting with AF/AE at up to 11fps
Never miss a moment of the action thanks to fast internal processing and high-capacity buffer memory. Fire off shots at up to 11fps with after-view or 8fps 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.
Silent continuous shooting at up to 8fps
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 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.
Newly adopted AI-based subject recognition technology processes a vast amount of data to detect and track even rapidly moving subjects.
Accurate eye recognition
Enhanced Real-time Eye AF 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 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 in mid-shoot.
Real-time Tracking 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.
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 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.
Creative movie production
From full-pixel readout without pixel binning enabling high-resolution 4K movie recording to HDR (HLG) and S-Log/S-Gamut options and Slow & Quick Motion recording, the α6400 is loaded with advanced capabilities to support your movie-making creativity.
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 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 adaptor (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) can be recorded in the camera, without post-processing on a PC. Alternatively, 120fps high-speed shooting 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.
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, and when you're setting up the function menu you can view the structure of the actual function screen.
