Sony Alpha a6400 Mirrorless Digital Camera Body
APS-C Format Hybrid Mirrorless – 24.2MP Exmor CMOS Sensor, BIONZ X Processor with Front-End LSI, 425-Point 4D FOCUS with Real-Time Eye AF & Tracking, UHD 4K Video with S-Log3/HLG, 180° Tilting Touchscreen LCD

The Sony Alpha a6400 is an advanced, lightweight APS-C format mirrorless camera engineered for content creators, vloggers, hybrid shooters, and action photographers. Powered by a 24.2-megapixel APS-C Exmor CMOS sensor with thin copper wiring and enhanced circuitry, paired with the BIONZ X image processor and front-end LSI, the a6400 delivers exceptional image clarity, low noise, and rich tonal rendering across a native sensitivity range of ISO 100 to 32,000 (expandable to ISO 102,400). The camera supports continuous burst shooting at up to 11 frames per second with full AF/AE tracking (or 8 fps with the silent electronic shutter) and outputs 14-bit RAW files for extensive post-production flexibility.

Engineered with Sony’s class-leading 4D FOCUS system, the a6400 features 425 focal-plane phase-detection points and 425 contrast-detection zones covering approximately 84% of the image area to achieve autofocus acquisition speeds as fast as 0.02 seconds. AI-driven Real-Time Tracking and Real-Time Eye AF (for humans and animals) provide continuous, reliable subject lock for both high-resolution stills and video. For filmmakers, the camera records oversampled UHD 4K video using the full sensor width with 6K readout (no pixel binning), Full HD at up to 120 fps for slow motion, advanced picture profiles including S-Log2, S-Log3, and HLG (Hybrid Log-Gamma), clean 4:2:2 uncompressed HDMI output, and built-in interval shooting for time-lapses. The compact magnesium-alloy chassis is equipped with a 2.36m-dot OLED EVF, a 3.0-inch 180-degree flip-up touchscreen LCD for front-facing monitoring, a 3.5mm external microphone input, and comprehensive wireless connectivity.

CONDITION DIAGNOSTICS & PHYSICAL NOTES
