Overview

The Sony a6400 is built around a 24.2-megapixel APS-C Exmor CMOS sensor paired with the BIONZ X image processor, a combination that delivers detailed stills and oversampled 4K video with natural color rendition. Its autofocus system is the camera's standout feature: 425 phase-detection points blanket nearly the entire sensor area, and Real-Time Eye AF tracks human and animal eyes with remarkable tenacity, acquiring focus in as little as 0.02 seconds. Continuous shooting at 11 frames per second with full AF/AE tracking makes the a6400 capable of handling sports, wildlife, and fast-paced event photography despite its compact form factor. The ISO range extends from 100 to 32,000 natively, expandable to 102,400, providing usable results in low-light conditions.

For video creators, the a6400 records UHD 4K internally with full pixel readout — no line skipping or pixel binning — resulting in detailed, clean footage. S-Log2, S-Log3, and HLG gamma profiles give editors the dynamic range headroom to color grade footage to a professional standard. The 180° tilting touchscreen is a practical addition for vloggers and solo shooters, offering touch-to-focus functionality and self-framing without an external monitor. Built-in Wi-Fi with NFC and Bluetooth enable wireless image transfer and remote camera control via a smartphone. This bundle includes a 64GB SDXC card, soft carrying case, flexible tripod, hand strap, memory card reader, lens cap keeper, and cleaning kit — essential accessories to start shooting right out of the box.
