Sony FX3a camera: Sony’s FX3a refines an already strong cinema camera with targeted upgrades and video-centric features that serve today’s creators. It keeps the same full-frame 12.1 MP Exmor R sensor, BIONZ XR processor, and real-time Eye AF from the original FX3, while adding a higher-resolution LCD, USB-C power delivery, enhanced HDR profiles, 16-bit RAW HDMI output, and a detachable XLR handle for pro audio. Priced around $3,900, it sits between Sony’s FX30 and FX6, offering filmmakers a compact, ready-to-shoot package that balances image quality, workflow flexibility, and durable design.

Price of the Sony FX3a camera
Sony lists the FX3a body at $3,899.99, and major retailers match that street price. Sony’s online store offers 0 % financing over 24 months, making high-end capture more accessible.
Operating System of the Sony FX3a camera
The FX3a relies solely on its firmware and Sony’s menu interface—there is no general-purpose operating system. Firmware updates install via Sony’s desktop updater, ensuring the camera stays current without adding unnecessary complexity.
Battery of the Sony FX3a camera
Power comes from the NP-FZ100 battery, rated for over 150 minutes of continuous 4K/60 fps recording. A recent internal redesign removes NFC and IR circuitry to make room for USB-C power-delivery support, so you can run the camera off compatible USB-C PD power banks for extended shoots.
Display of the Sony FX3a camera
Sony upgraded the rear LCD to 2.36 million dots, up from 1.44 million on the FX3, for sharper focus peaking and clip review. The 3.0″ side-flippable touch screen maintains its articulating design, letting you frame low-angle, high-angle, and rig-mounted shots with ease.
Design of the Sony FX3a camera
The FX3a preserves the FX3’s cage-free, handheld form factor at 129 × 77 × 84 mm and 715 g (with handle), built from magnesium alloy for strength without weight. Five ¼-20 UNC threads sit on three sides for direct accessory mounting, and the top handle attaches via the Multi Interface Shoe, offering two full-size XLR inputs and phantom-power support for pro audio.
New Cinematic Freedom & Video Features
Sony positions the FX3a as a tool for “passionate content creators,” blending reliable performance with streamlined operation in a portable package. Key video features include:
- 10-bit S-Log3 & S-Gamut3.Cine for smooth tonal gradations and easy color matching across Cinema Line cameras.
- HLG (Hybrid Log-Gamma) HDR profile enabling direct HDR playback on compatible displays without post-production.
- 16-bit RAW output via HDMI at 4264 × 2408 (16:9), exceeding DCI-4K resolution, while internally recording XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K plus proxy files.
- Attachable XLR handle with two full-size XLR connectors, offering clean audio input and stable grip for handheld or challenging-angle shooting.
How It Differs from Other Cinema Cameras
- Mount & Sensor: Uses Sony’s E-mount with a full-frame Exmor R sensor, unlike competitors that pair Super 35 or RF-mount sensors.
- Form Factor: Delivers a cage-free, ready-to-shoot chassis rather than a modular rig that requires external cages and brackets.
- Autofocus: Fast Hybrid AF with Real-time Eye AF offers point-and-shoot focus tracking, outpacing many cinema cameras that rely solely on manual focus pulls.
- Workflow Flexibility: Internal 10-bit 4:2:2 XAVC S-I recording plus 16-bit RAW over HDMI and proxy capture speeds up both shooting and editing.
- Price Tier: Occupies a mid-range price point—below full-size cinema bodies like the FX6 but above entry-level models such as the FX30, while retaining full-frame benefits.
