Sony Alpha a6400 Mirrorless Digital Camera Body
APS-C Hybrid Workhorse – 24.2MP Exmor CMOS Sensor, BIONZ X Processor, 0.02s 4D FOCUS System & 180° Tilting Touchscreen

The Sony Alpha a6400 is a sleek, highly versatile APS-C-format mirrorless camera body designed for content creators, vloggers, and photographers seeking rapid performance and advanced hybrid video capabilities. Powered by a 24.2MP Exmor CMOS sensor paired with the BIONZ X image processor and front-end LSI, the a6400 delivers sharp image rendering, low-noise performance from ISO 100 to 32,000 (expandable to ISO 102,400), and continuous burst shooting up to 11 fps with full AF/AE tracking.

Equipped with Sony’s advanced 4D FOCUS system, the camera features 425 phase-detection and 425 contrast-detection AF points covering nearly the entire sensor to acquire focus in as little as 0.02 seconds. Real-time Eye AF and Real-time Tracking ensure critical focus accuracy on moving human and animal subjects across both stills and video workflows. For filmmakers, the a6400 records oversampled 4K UHD video (from a 6K capture area) using the XAVC S codec with full pixel readout, featuring S-Log2, S-Log3, and HLG (Hybrid Log-Gamma) profiles alongside Full HD high-speed recording up to 120 fps. Housed in a durable chassis, it features a 180° upward-tilting 3.0-inch touchscreen LCD for selfie framing, a 2.36m-dot OLED electronic viewfinder, a 3.5mm external microphone port, and built-in Wi-Fi/Bluetooth connectivity.
