a6400 E-mount camera with APS-C Sensor
Lightweight, compact and sturdily built, the a6400 is loaded with impressive capabilities and features. With super-fast AF and highly precise subject tracking, it's ideal for capturing fast-moving action, while its wide sensitivity range and stunning image quality make it suitable for just about any photographic opportunity you may encounter, whether you're shooting stills or movies.
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 sec1 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-22 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 color-highlights the most sharply focused section of the entire image area when you're using manual focus. Blue has now been added to the display's other peaking colors (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 color, pattern (brightness), subject distance (depth) and face/eye information to recognize, 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 minimized, and up to 116 JPEG (Standard) images5 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-megapixel7 ExmorTM CMOS sensor provides a wide sensitivity range and excellent low-noise performance. In conjunction with the new-generation BIONZ XTM 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 colors, including human skin tones and natural plant colors.
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 35 mm format, 4K movie recording with full pixel readout and no pixel binning allows oversampling with approx. 2.4x9 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. 100 Mbps) XAVC S8 format, a consumer-friendly version of a format for professional use, plus HLG support result in better-looking movies.
S-Gamut/S-Log shooting
S-Log shooting gives you flexibility to make more expressive movies by performing color grading in post-production. The S-Log3 and S-Log2 gamma curves feature a wide dynamic range (up to 1300%) that can help minimize 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 100 Mbps in Full HD can be used to create high-image-quality slow-motion movies in post-production.
Sophisticated features for easier movie-making
The a6400 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 adapter 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 Edge desktop applications. A simple variable-speed preview function allows you to see an image on the camera of how the finished movie will look.
180 Degree -tiltable LCD screen with versatile touch functions
The high-resolution 921k-dot LCD has a 3.0-type screen and tilts up a full 180 Degree 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 provides high visibility, fine details even in dark areas, accurate colors 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.
