High-speed, high-precision, high-tracking AF that instantly captures and holds the subject. The high-density 425-point full-area phase-detection AF sensor inherits the motion prediction algorithm of full-frame cameras, and features the world's fastest response time of 0.02 seconds*. High-density AF tracking technology delivers high AF accuracy and moving subject tracking performance. Even moving subjects with complex movements that are difficult to capture can be tracked more quickly and accurately. *: As of the press release in January 2019, according to Sony research. For digital SLR cameras with APS-C sensors. Compliant with CIPA guidelines, internal measurement method. Pre-AF off, when using the viewfinder. With E 18-135mm F3.5-5.6 OSS attached.
Real-time Eye AF with improved detection accuracy and speed. The Bionz X's high image processing capabilities and technology developed for full-frame cameras significantly improve eye detection accuracy, speed, and tracking compared to the α6300's Eye AF. Maintaining focus on the eye is now easy and reliable, even when shooting moving portraits. Stable AF tracking of the eye allows for smooth shooting.
[Fast] Fast Hybrid AF: World's Fastest* AF Speed ​​of 0.02 Seconds The Fast Hybrid AF system combines phase-detection AF, which boasts excellent speed and tracking, with high-precision contrast-detection AF. Furthermore, the new-generation BIONZ X, optimized for the α6400, achieves the world's fastest AF speed of 0.02 seconds*. Even fast-moving subjects can be captured instantly. *: Based on Sony research as of the press release in January 2019. For digital SLR cameras with an APS-C sensor. Compliant with CIPA guidelines, internal measurement method, with pre-AF off and viewfinder in use. When using the E 18-135mm F3.5-5.6 OSS lens attached: Touchpad function allows you to adjust the focus while looking through the viewfinder. The touchpad function allows you to move the focus frame by tracing the monitor like a touchpad. The focus position changes according to the amount of finger movement on the monitor, allowing you to smoothly adjust the focus while looking through the viewfinder. Equipped with an approximately 24.2-megapixel APS-C Exmor CMOS sensor and an advanced image processing system, the camera features an APS-C-sized approximately 24.2-megapixel CMOS sensor. High light-gathering efficiency achieved through copper wiring and a highly efficient circuit process delivers a wide sensitivity range and excellent low-noise performance even at high sensitivity. Furthermore, the faster readout speed enables features such as 4K video recording with full pixel readout without pixel binning and Full HD 120fps shooting. Furthermore, the camera is equipped with the new-generation BIONZ X image processing engine and a front-end LSI that supports BIONZ X image processing. Optimized image processing algorithms further improve resolution and texture depiction. Dramatically increased light-gathering efficiency, resulting in even higher sensitivity and lower noise. The adoption of copper wiring and circuit process miniaturization allows for high-light-gathering process technology to minimize pixel wiring layers, while the wide photodiode design expands the light-receiving area of ​​the photodiode that captures light. This dramatically increases light-gathering efficiency and significantly improves the signal-to-noise ratio per pixel, resulting in higher sensitivity and lower noise for superior image quality. High-sensitivity shooting performance with a maximum ISO of 102400. Maximizing the performance of the APS-C image sensor, the camera achieves a standard ISO sensitivity of 100-32000 and an extended ISO sensitivity of up to 102400*. It delivers both high resolution and low noise across a wide sensitivity range. A high-speed shutter allows for reduced camera shake even in low-light situations, enabling you to capture images that capture atmosphere without using a flash. *High-sensitivity shooting performance with a maximum ISO of 102400. Extended maximum ISO sensitivity for still photography. Maximum ISO of 32000 for video. Silent shooting with AF/AE tracking. Silent continuous shooting at up to 8 frames per second is now possible, even during high-speed continuous shooting. Capture quiet scenes without worrying about the shutter sound, so you'll never miss a decisive moment. It can also be used in conjunction with AF-C, Real-time Eye AF, and Real-time Tracking. Supports a 1:1 aspect ratio for easy social media posting. In addition to 3:2 and 16:9 aspect ratios, you can now also select the 1:1 aspect ratio commonly used on social media. Posting is hassle-free, eliminating the need for post-capture. 180-degree tilting LCD monitor for easy selfies. The tilting LCD monitor can be adjusted up to approximately 90 degrees upward and down to approximately 74 degrees downward. You can comfortably shoot from a variety of positions and angles, whether you're shooting high or low to match the eye level of a child or animal. It can also be rotated 180 degrees, making it easy to take selfies while checking the composition. Furthermore, you can adjust the focus, operate the shutter, and automatically track the subject simply by touching the LCD monitor, further increasing the flexibility of the position and angle.
