An innovative image-processing system
The camera's APS-C size, 24.2-megapixel ExmorCMOS sensor provides a wide sensitivity range and excellent low-noise performance. In conjunction with the new-generation BIONZ X image 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.
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. 2.4x19 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.
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 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.
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.
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.
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.
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.
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.
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.
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.
