Sony a9 Mirrorless Camera with Battery Grip

Sony Alpha a9 Mirrorless Digital Camera (Body Only)
High-Speed Flagship Action & Sports Camera – Good Condition with Upgraded Battery Grip
The Sony Alpha a9 is a groundbreaking, sports-centric full-frame mirrorless camera engineered from the ground up for high-speed action, journalism, and wildlife professionals. It features a revolutionary 24.2MP Exmor RS stacked CMOS sensor—the first of its kind for full-frame—paired with a high-torque BIONZ X processing engine. This hardware fusion eliminates the standard physical limits of mirrorless capture, delivering an incredible blackout-free 20 fps continuous shooting speed, 60 AF/AE tracking calculations per second, and a silent electronic shutter speed up to 1/32,000s.

Bolstered by a dense 693-point phase-detection hybrid AF network and 5-axis sensor-shift hardware stabilization, the a9 captures transient moments with flawless precision. Please note: This camera body is in good, fully operational condition. It has been upgraded with a Neewer multi-battery vertical grip, but is missing its original small body battery door and hot shoe cover plate.

Key Features & Technical Engineering
24.2MP Full-Frame Stacked CMOS Sensor: The groundbreaking Exmor RS stacked architecture features an integrated high-speed signal processing circuit and memory, delivering blazing readout speeds. Its back-illuminated (BSI) design minimizes noise, expanding sensitivity to an extended ISO 204,800 while preserving rich 14-bit uncompressed RAW data.

Continuous 20 fps Blackout-Free Capture: Captures high-speed action at a blistering 20 fps for up to 362 consecutive JPEGs or 241 RAW frames. The electronic viewfinder offers completely blackout-free monitoring, ensuring you never lose sight of an erratic subject mid-burst.

Hyper-Fast AF/AE Calibrations: The automated tracking system computes autofocus and auto-exposure corrections up to 60 times per second, maintaining continuous subject acquisition even during high-speed directional changes.

693-Point Phase-Detection AF Array: Covers an expansive 93% of the image frame with 693 phase-detection and 25 contrast-detection points, operating reliably down to -3 EV. Features advanced High-density Tracking AF, real-time Eye AF, and Expand Flexible Spot tracking logic.

5-Axis SteadyShot INSIDE Stabilization: Provides up to 5 stops of physical image stabilization correction for pitch, yaw, roll, and vertical/horizontal shift. This sensor-shift technology actively stabilizes any attached optic, including legacy adapted lenses.

Oversampled UHD 4K Video: Records internal UHD 4K video at up to 30 fps using full-pixel readout with 2.4x oversampling for crisp detail with minimal moiré. Also records high-speed Full HD 1080p footage at up to 120 fps for fluid 4x and 5x slow-motion playback via the XAVC S format.

Professional Body Design & Connectivity
High-Refresh Quad-VGA EVF: Features a bright 3.68m-dot OLED electronic viewfinder with 0.78x magnification, treated with a premium ZEISS T* anti-reflective coating. Operates at a smooth 120 fps refresh rate to minimize display lag.

Tilting Touchscreen LCD: Outfitted with a 3.0″ 1.44m-dot tilting rear touchscreen panel that tilts upward and downward for dynamic low- or high-angle framing, featuring Touch Focus capabilities.

Dual Media Slots & Physical Dials: Includes dual SD card slots (Slot 2 supports high-speed UHS-II media) for flexible partitioning or overflow saving. The top deck incorporates stacked physical drive mode and focus mode dials for immediate tactical changes in the field.

Wired LAN & Studio Connectivity: Built with an integrated RJ45 Ethernet LAN terminal for high-speed wired FTP studio transfers, alongside a dedicated PC Sync port for studio strobe integration, Wi-Fi, Bluetooth, and one-touch NFC smartphone pairing.

Item Condition & Packaging Diagnostic Notes
Operational Status: Good overall condition. The internal stacked sensor is pristine, the electronic shutter performs flawlessly, and the hybrid tracking array locks on target reliably.

Physical & Cosmetic Discrepancies: The camera chassis shows standard cosmetic wear from professional field handling.

No Battery Door: The original detachable camera body battery door flap is missing. Note: This is standard practice when a battery grip is permanently installed, as the grip’s power stem slots directly into the empty compartment.

No Shoe Cover: The small plastic hot shoe protector cover plate is missing from the top deck.

Included Upgrades & Accessories:

Neewer Brand Battery Vertical Grip: Comes pre-installed, offering secondary portrait orientation controls and extended battery capacity slots.

High-comfort rubber viewfinder eyecup.

Compatible front body cap. (Batteries and charger are sold separately unless specified).
