Sony Alpha a6400 Mirrorless Camera Body
High-Speed APS-C Content Creation Workhorse Well Used
The Sony a6400 is a sleek, highly capable APS-C format mirrorless camera designed to meet the rigorous demands of everyday vloggers, travel photographers, and multimedia content creators. Powered by a 24.2MP Exmor CMOS sensor and the advanced BIONZ X processing engine, this camera delivers exceptionally clean, low-noise imagery with a native sensitivity reaching ISO 32000. It is widely celebrated for its elite 4D FOCUS system, featuring real-time AI subject tracking and Eye AF that locks onto targets in a mere 0.02 seconds. Complete with an internal, oversampled UHD 4K movie mode and a 180° tilting touchscreen LCD, the a6400 packs professional-grade tracking and cinema tools into a compact, highly portable chassis. Please note: This specific unit is well used and exhibits heavy exterior scuffing.
Key Features & Engineering
24.2MP Exmor CMOS Sensor & BIONZ X Processor: Features an optimized copper-wired sensor architecture paired with a front-end LSI to maximize light-gathering efficiency and read-out speeds. Supports a broad sensitivity range (expandable up to ISO 102400) and produces detailed 14-bit RAW output.
11 fps Continuous Still Shooting: Captures fast-moving action sequences at up to 11 fps with full-time autofocus and auto-exposure tracking, or up to 8 fps when utilizing the silent electronic shutter mode.
Oversampled UHD 4K Video: Records internal UHD 4K video up to 30 fps using a 6K oversampled region of the sensor with full pixel readout and no pixel binning. This processing workflow drastically reduces moiré and aliasing, saving files in the 100Mbps XAVC S codec.
Pro Cinema Profiles (S-Log & HLG): Outfitted with advanced color grading profiles including S-Log2, S-Log3 (yielding an effective 14-stop dynamic range), and instant HDR-compliant Hybrid Log-Gamma (HLG) curves mapped to the BT.2020 wide color gamut.
Creative S&Q and Interval Tools: Features a Slow & Quick (S&Q) video engine for capturing Full HD footage at frame rates ranging from 1 to 120 fps for dramatic motion manipulation. Includes an integrated interval timer for shooting up to 9,999 sequential frames for time-lapse creation.
Class-Leading 4D FOCUS System
0.02-Second Hybrid AF Matrix: Combines 425 phase-detection points and 425 contrast-detection zones covering nearly the entire sensor plane to provide instantaneous, precise focus lock.
Real-Time AI Tracking & Eye AF: Utilizes deep-learning algorithms to identify and track human and animal subjects in real time. Real-time Eye AF operates continuously across both still photography and video tracking modes.
Touchscreen Focus & Touchpad Control: The rear display acts as a customizable tracking touchpad, enabling shooters to drag focus coordinates seamlessly across the plane without taking their eye off the electronic viewfinder.
Body Design & Layout
180° Tilting Touchscreen LCD: Features a 3.0″ 921.6k-dot rear LCD screen that flips up a full 180° for effortless vlogging and self-tape composition. Built with White Magic RGBW technology for enhanced viewing visibility in bright daylight.
XGA OLED Tru-Finder EVF: Equipped with a high-resolution 2.36m-dot OLED electronic viewfinder for crisp, eye-level framing and reliable composition evaluation.
Wired & Wireless Studio I/O: Features an integrated 3.5mm microphone terminal for professional external audio capture. Built-in Wi-Fi, NFC, and Bluetooth allow for instant file transferring, remote smartphone shutter control, and automated GPS location data tagging.
Item Condition & Notes
Cosmetic Condition: Well used. The exterior camera body shows heavy, prominent scuffing, finish wear, and rubbing along the corners, base plate, and high-contact grip areas from extensive field use. These blemishes are strictly cosmetic.
Mechanical & Electronic State: Fully functional. Despite its heavily worn cosmetic appearance, the camera operates perfectly. The image sensor is pristine, the shutter mechanism fires crisply, the inputs/outputs maintain secure connections, and the EVF and rear touchscreen operate flawlessly.
