24.2MP and incredible image quality
The a6400’s APS-C image sensor with approximately 24.2 effective megapixels uses copper wiring and a highly effective circuit process, resulting in efficient light collection that achieves a wide sensitivity range (Expandable ISO 100 – 102400) and excellent low noise performance even at high ISO. The design significantly increases readout speed, enabling functionality including 11fps continuous shooting3, 4K recording2 with full pixel readout without pixel binning and Full HD 120fps high-speed shooting. A front-end LSI supports the image processing of the new-generation BIONZ X image processing engine. Advances in image processing algorithms have further improved the superb image clarity, texture reproduction and image quality.
World’s fastest autofocus1 with 4D FOCUS
The α6400’s unrivaled 4D FOCUS™ system boasts the world’s fastest autofocus (AF) acquisition time1 that can lock focus on even the fastest moving subject in as little as 0.02 seconds1. It also boasts an incredible 425 phase detection and 425 contrast detection AF points that are densely positioned over 84% of the image area, effectively tracking subjects as they move across the frame. Moreover, the α6400 takes full advantage of its enhanced fast hybrid AF for movies in both HD and 4K2. With the optimized new-generation subject motion prediction algorithm from the α9. Both AF detection accuracy and tracking performance have been boosted.
Advanced Real-time Eye-AF
Advanced “Real-time Eye AF” employs artificial intelligence to detect and process eye data in real time, resulting in improved accuracy, speed and tracking performance of Eye AF. With a half press of the shutter button, the camera can automatically detect the eyes of the subject and activate Eye AF in all autofocus modes and when in either AF-C or AF-A mode, eye capture is continuously maintained. Additionally, 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 is assignable to a custom function as well.
“Real-time Tracking” utilizes a special object recognition algorithm that processes color, subject distance (depth), brightness (pattern) as spatial information, plus AI information including face and eye location, ensuring that all subjects can be captured with extreme accuracy and precision. This can be activated by a simple half press of the shutter button, or can be assigned to a custom function as well.
Up to 11fps3 at 24.2MP with AE/AF tracking
The α6400 has been designed to allow for high resolution, continuous shooting at high frame rates. It features a front-end LSI that works with the image sensor, BIONZ X image processing engine and a newly designed shutter mechanism with ‘braking feature’ to enable continuous shooting at impressive speeds up to 11fps3 with continuous autofocus and auto-exposure tracking at full 24.2MP resolution while utilizing the mechanical shutter, and up to 8 fps3 with full AF/AE tracking while silent shooting. The α6400 can also shoot continuously for up to 116 JPEG and 46 compressed RAW frames4, thanks to a large buffer. These shots can be viewed immediately after shooting, even when in high-speed continuous shooting mode.
4K movie2 w/ 2.4x oversampling4, full pixel readout, no pixel binning
The α6400 offers internal 4K (QFHD: 3840 x 2160) recording2 in Super 35mm format with full pixel readout and no pixel binning at 2.4x oversampling4 (6K equivalent) for the ultimate 4K footage with exceptional detail and depth. Additional professional video features include; HDR (HLG), S-Gamut3/S-Log3and 3, plus Gamma Display Assist, the ability to record Full HD at 120 fps for up to 5x slow motion HD video7, both a mic jack and XLR compatibility via the MI shoe, enhanced Zebra functionality, focus peaking, picture profile settings, as well as Time Code / User Bit, clean HDMI output and much more.
Effective use of the focal plane phase-detection system makes focusing during movie shooting fast and stable. The upgraded Fast Hybrid AF technology keeps your subject in constant smooth focus no matter the scene. This advanced AF plus touch focus functionality on the 180-degree titlable LCD make it an ideal camera choice for many vloggers and video creators that are regularly creating and uploading content online. Touching the subject that you wish to focus on the screen initiates accurate and smooth continuous focus tracking, while analyzing color, brightness pattern, distance (depth) and face information. AF drive speed and AF Tracking Sensitivity are also adjustable to support creative movie making.
180-degree fully tiltable LCD touch screen for self-recording
The fully tiltable (180-degree), 3” (3.0-type) LCD flip screen with 921k-dots of high-resolution allows for simple and effective selfie-style shooting for both still image and video capture. Utilizing this capability, vloggers will be able to check and monitor composition throughout their entire creative process. The LCD screen is also equipped with touch functionality, with options for Touch Pad, Touch Focus, Touch Shutter and new Touch Tracking which quickly activates “Real-time Tracking” through the touch screen.
A wide variety of touch screen operations
The LCD offers a wide variety of touch operations enabling intuitive shooting and fast focus operation. The Touch Focus function allows the desired focus point to be specified instantaneously by touching the subject on the monitor. Touch Shutter function instantaneously focuses on the subject touched on the monitor and releases the shutter, so that the desired subject can be captured with one touch. The touchpad function allows smooth focus position adjustment while using the viewfinder. Sliding a finger across the monitor moves the focus area position and can be moved smoothly while looking through the viewfinder. Touch Tracking function, works by touching the subject that you wish to focus on the screen and then half-pressing the shutter button activates Real-time Tracking. When shooting movies, touching the subject initiates tracking that maintains focus on the subject.
