Sony a6400 Mirrorless Digital Camera Body
Compact APS-C Performance 24.2MP Exmor CMOS Sensor, BIONZ X Processor, 0.02s 4D FOCUS & 4K UHD Video
The Sony a6400 is a sleek, highly capable APS-C format mirrorless camera engineered for hybrid content creators, vloggers, and photographers. Powered by a 24.2MP Exmor CMOS sensor and the BIONZ X image processor with a front-end LSI, the a6400 produces high-resolution stills with low noise across a native ISO range of 100-32000 (expandable to ISO 102400). It supports fast continuous shooting up to 11 fps with full AF/AE tracking, alongside silent shooting up to 8 fps and 14-bit RAW output.
For video production, the a6400 records internal 6K-oversampled 4K UHD video using the full width of the sensor at up to 30 fps in 8-bit 4:2:2 XAVC S format. Advanced gamma profiles—including S-Log2, S-Log3 (offering up to 14 stops of dynamic range), and HLG (Hybrid Log-Gamma)—provide maximum color grading flexibility, complemented by uncompressed clean 4:2:2 4K HDMI output for external recorders. Slow & Quick (S&Q) Motion enables Full HD capture from 1 to 120 fps for dramatic slow-motion playback.
The camera’s flagship 4D FOCUS system utilizes 425 phase-detection and 425 contrast-detection AF points covering nearly the entire sensor to acquire focus in as fast as 0.02 seconds. Real-time Eye AF and Real-time Tracking leverage AI-based subject recognition for humans and animals across both still and video modes. Built into a durable magnesium-alloy body, it features a 2.36m-dot OLED electronic viewfinder, a 180° tilting 3.0-inch touchscreen LCD for front-facing vlogging, a 3.5mm external mic port, and wireless Wi-Fi, NFC, and Bluetooth connectivity.
