The Sony Alpha a7R III is an industry-benchmark, high-resolution full-frame mirrorless camera engineered to merge medium-format-rivaling resolving power with high-speed burst capture and cinema-grade 4K motion capabilities. Built around a back-illuminated 42.4-megapixel Exmor R BSI CMOS sensor devoid of an optical low-pass filter, the a7R III utilizes gapless on-chip lenses and anti-reflective coatings paired with Sony’s BIONZ X processing engine and high-speed front-end LSI. This architecture yields exceptional fine detail, rich 14-bit RAW output, and a broad 15-stop dynamic range at lower ISOs, operating across a native sensitivity range of ISO 100 to 32000 (expandable to ISO 50-102400). Despite its heavy pixel count, the camera executes full-resolution continuous bursts up to 10 frames per second with continuous AF/AE tracking across both its mechanical low-vibration shutter and silent electronic shutter modes, sustaining buffers up to 76 consecutive frames.

For tracking dynamic action and studio portraits, the upgraded Fast Hybrid AF system utilizes 399 focal-plane phase-detection points covering approximately 68% of the image area alongside 425 contrast-detection areas, providing reliable focus acquisition down to -3 EV and responsive Eye AF in both continuous and single-shot modes. In motion capture, the camera records internal UHD 4K (3840 x 2160) video up to 30p using either the full sensor width or Super 35 format with 5K oversampling and full pixel readout without pixel binning. Advanced video profiles include S-Log3 with 14 stops of latitude, S-Log2, and Hybrid Log-Gamma (HLG) for instant HDR delivery, alongside Full HD 1080p high-frame-rate capture up to 120 fps for 5x slow motion. Stabilized by a 5.5-stop 5-axis SteadyShot INSIDE mechanism that enables ultra-high-resolution 169.6MP Pixel Shift Multi Shooting, and supported by a Quad-VGA OLED Tru-Finder, tilting touchscreen LCD, dual SD card slots, and an extended-capacity NP-FZ100 battery system, the a7R III delivers versatile professional capability.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: COMPLETE CAMERA BODY OUTFIT. Supplied with the Sony Alpha a7R III mirrorless camera body, genuine Sony NP-FZ100 rechargeable lithium-ion battery, body cap, and hot shoe cover. (Sony E-mount lenses, SD memory cards, external battery wall chargers, and interface cables sold separately unless pictured).

Exterior & Chassis Status: GOOD CONDITION. The magnesium-alloy chassis, textured rubberized handgrip, rear thumb rest, top dials, and interface port doors show normal signs of regular field use, including light-to-moderate surface scuffs, shallow finish rub marks, and minor edge wear along the baseplate corners and prism housing. All engraved dial indices, button labels, and Sony Alpha badging remain intact, clean, and fully legible.

Sensor & Chamber Status: EXCELLENT CONDITION. The 42.4MP full-frame Exmor R BSI CMOS sensor glass is pristine, clean, and completely free of scratches, scuffs, cleaning marks, or sensor stains. The reinforced six-screw stainless steel E-mount bayonet and gold-plated electronic contacts are clean and tight with no mounting play or contact wear.

Viewfinder & Display Status: GOOD CONDITION. The 3.69m-dot Quad-VGA OLED Tru-Finder electronic viewfinder is bright, clear, and free of optical blemishes or dead pixels. The rear 3.0-inch 1.44m-dot tilting LCD monitor exhibits light cosmetic surface scuffs consistent with standard handling that do not impede image playback, live view framing, or touch-focus operations; the dual-hinge tilt mechanism articulates smoothly with firm factory resistance.

Mechanical & Electronic Status: FULLY FUNCTIONAL. The low-vibration focal-plane mechanical shutter releases cleanly across all speeds up to 1/8000s and 10 fps; 399-point Fast Hybrid AF and Eye AF lock swiftly and track accurately; UHD 4K and Full HD 120p video write reliably to both memory card slots; the 5-axis SteadyShot INSIDE mechanism operates silently; Pixel Shift Multi Shooting functions properly; dual SD card slots (including UHS-II Slot 1), USB-C, micro-USB, micro-HDMI, PC sync, and 3.5mm audio ports make solid, error-free connections; Wi-Fi and Bluetooth pair without issue.
