Expressive UHD 4K Video Capture
The FX3A's 12.1MP Exmor R BSI CMOS sensor (10.2MP effective in video mode) is paired with a BIONZ XR processor to achieve UHD 4K video capture with internal 10-bit 4:2:2 sampling or 16-bit raw output. The sensor's BSI design heightens clarity and sensitivity, with an expandable ISO 80-409,600 range and a greater-than-15-stop dynamic range for working in mixed lighting conditions. Benefiting color and tonal control, the S-Cinetone mode can be used for matching to VENICE, FX9, or FX6 sources, and there is also S-Log3/2 gamut support and 10-bit HLG for simple HDR productions. The sensor and processor also work together to greatly reduce rolling shutter, and the sensor's design incorporates a Fast Hybrid AF system for intelligent and quick focusing performance and subject tracking.
4K Full-Frame CMOS Exmor R Sensor
A 12.1MP Exmor R sensor and BIONZ XR processor offer the FX3A true cinematic expression with 10.2MP effective video and 12.1MP still capture. The full-frame sensor provides shallow depth of field looks, impressive bokeh, and reduced rolling shutter artifacts. A base sensitivity of 80-102,400 expands to a lofty 409,600 for impressive low-light capture, and 15+ stops of dynamic range reproduce the nuances of both spectacular exteriors and carefully lit interior scenes with plenty of allowance for color grading.
S-Cinetone Color
Beautiful skin tone reproduction and a softer-toned look that complements your VENICE, FX9, or FX6 footage are created using the FX3A's default S-Cinetone color setting. S-Log-3, S-Gamut3, S-Gamut3.Cine, and 10-bit 4:2:2 support help maintain rich gradation and color matching with the range of Sony Cinema Line cameras, while HLG HDR provides the option of direct HLG playback without the need for grading.
Video Recording
Capture sharp, detailed images at rates up to 4K 120p with up to 5x slow motion at 24p output. Recording options include the ability to output DCI 4K+ in 16-bit raw over HDMI to compatible recorders while simultaneously recording XAVC 4K and proxies in-camera. Internal 4K recording options include 4:2:2 10-bit color with All-Intra and Long GOP codecs.

Ergonomic Form for Solo Operation
The FX3A's cage-free design enables you to mount ¼"-20 compatible accessories directly on the camera or the detachable handle, saving you the weight and setup/breakdown time of a camera cage. The clustered record button, focus and menu controls, and six assignable buttons all help to enable single-handed control, leaving your left hand free for balancing or controlling your lens.
Tilting Touchscreen LCD
The fold-out 3" touchscreen LCD has a crisp 2.35MP resolution and can be variously angled for optimal viewing.
