Stable, fast, versatile, and compact, the Alpha a6400 from Sony is an APS-C-format mirrorless camera that adopts many of the features normally reserved for their full-frame lineup. This includes an autofocus acquisition of 0.02 seconds, Real-time Eye AF and Real-time Tracking capabilities, high-speed shooting up to 11 fps and silent shooting up to 8 fps, both with AF/AE tracking, an upgraded BIONZ X image processing engine, a fully tiltable 180ø LCD touchscreen, UHD 4K movie recording with full pixel readout and no pixel binning, internal recording for time-lapse videos, and more.
The a6400 is well-suited for both photo and video creators, ranging from professionals to vloggers. Revolving around a 24.2MP Exmor CMOS sensor and BIONZ X image processor, clean image quality is provided with a wide expandable sensitivity range of ISO 100 to 102,400, along with accelerated readout speeds for internal 4K30 and Full HD 1080p120 video recording with full pixel readout. The processor further benefits videographers with the inclusion of an S&Q (Slow&Quick) Motion setting that permits capturing Full HD video at a variety of frame rates ranging from 1-120 fps, plus HLG (Hybrid Log-Gamma), which supports HDR workflows, and both S-Log2 and S-Log3 for color grading flexibility. Stills shooters also benefit from the processing speed, which enables continuous shooting at 11 fps for up to 116 JPEGs or 46 raw images in a burst, as well as 14-bit raw file output. The sensor and processor combination also avails wide-coverage 425-point phase-detection and 425-point contrast-detection systems for quick and precise focusing performance. This focusing system also enables Real-time Eye AF, which delivers improved accuracy, speed, and tracking performance of Eye AF, so the eyes of your subject are automatically detected. Furthermore, Real-time Tracking uses AI-based object recognition and processes color, subject distance (depth), and pattern (brightness) as spatial information to ensure that all subjects can be captured with accuracy. Increasingly versatile and fully featured in both photo and video realms, the a6400 is a fast and precise imaging tool for multimedia capture.
Complementing the imaging assets, the a6400 sports a robust magnesium-alloy body and anti-dust functionality that protects the optical filter. The compact profile incorporates a high-resolution XGA Tru-Finder 2.36m-dot OLED electronic viewfinder for bright, clear, eye-level viewing, and this EVF features a 120 fps viewing mode for smooth tracking of fast-moving subjects. A rear 3.0" 921.6k-dot touchscreen TFT LCD monitor is also available and tilts 180ø up and 74ø down to benefit shooting from high and low working angles. The touchscreen design also allows for intuitive touch-to-focus control. Additionally, for wireless remote control over the camera, or for just sharing imagery online, built-in Wi-Fi with NFC permits linking with a mobile device for intuitive wireless control.
Capture Decisive Moments
The autofocus system on the a6400 inherits many technologies from Sony's line-up of full-frame cameras, including the a9, a7R III, and a7 III models. The a6400 features 425 phase-detection AF points and 425 contrast-detection AF points that are placed densely over the entire image area, covering approximately 84% of the image area. This high-speed, high-performance tracking AF system is paired with a BIONZ X image processing engine that together allow the camera to acquire focus in as little as 0.02 seconds and maintain subject lock effectively, ensuring even the fastest
