The Sony Alpha a6400 Mirrorless Digital Camera Body 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, an LCD touchscreen that tilts 180° up and 74° down, 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 4K24 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, 46 raw images, or 44 raw and JPEG frames in a burst, as well as 14-bit raw file output. The sensor and processor combination also avails 4D FOCUS, with a wide-coverage 425-point phase-detection system that covers around 84% of the image area, and a 425-point contrast-detection system, both of which provide 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.
