24.2MP and incredible image qualityThe a6400s 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.Worlds fastest autofocus1 with 4D FOCUS™The a6400s unrivaled 4D FOCUS™ system boasts the worlds 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 a6400 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 a9. Both AF detection accuracy and tracking performance have been boosted.Advanced Real-time Eye-AFAdvanced "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 AF"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 trackingThe a6400 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 a6400 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 binningThe a6400 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.Fast Hybrid AF allows smooth focusing for movies 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 moviemaking.Interval recording for time-lapse videos Time-lapse movies document changes with the passing of time. The a6400 features built-in interval recording, for time-lapse movie creation, that can be set anywhere between 1 and 60 seconds, with a total number up of shots from 1 to 9999. AE tracking sensitivity can be adjusted to "High", "Mid" or "Low" during interval shooting, allowing for reduced changes in exposure over the shooting interval. The still images shot can then be edited into a time-lapse movie on a computer with the Viewer software from the Imaging Edge software suite5. A convenient variable-speed preview function is also provided to get an image, on the camera, of how the finished movie will look. Combining with silent shooting means that you need not worry about durability of the mechanical shutter. When interval shooting is carried out over a long period, the camera can use an optional mobile battery or the multi-battery adaptor kit NPA-MQZ1K to supply power (not provided), so shooting outdoors and/or for extended periods is worry-free.HDR video with LG (Hybrid Log-Gamma) HLG (Hybrid Log-Gamma) 6 picture profile that supports an instant HDR workflow. Recorded movies played back on an HDR (HLG) 6 compatible TV, without the need for color grading, will appear true-to-life, with no blocked shadows or blown highlights. The BT.2020 color space is supported, providing a wider color gamut. Four gamma settings are provided (HLG, HLG1, HLG2, HLG3). The HLG setting conforms to ITU-R BT.2100, while The HLG1, HLG2, and HLG3 gamma settings provide wider dynamic range. The balance of dynamic range and noise produced by each setting is different, allowing selection to best match the scene being recorded.S-Log shooting support7 The S-Log3 and S-Log2 Gamma7 curves feature wide dynamic range (up to 1300%) to minimize whiteout and blackout, and permit wider movie expression by performing color grading in post-production. The S-Log3 gamma setting further realizes a 14-stop latitude. The S-Gamut, S-Gamut3, and S-Gamut3.Cine color spaces are handled. A wide variety of professional end-uses such as cinema and broadcast are supported. Zebra functionChecking exposure is often difficult e
