Rent NowThe Sony FX3 is a compact, lightweight full-frame cinema camera built for solo content creators, filmmakers, and mobile production teams who want Cinema Line image quality in a genuinely portable, cage-free body. It merges elements from Sony’s Cinema Line and Alpha camera series, positioning it as an ideal B-camera companion or a primary tool for travel filmmaking and run-and-gun production.
At the core of the FX3 is a 12.1MP full-frame back-illuminated Exmor R CMOS sensor (10.2MP effective for movies), paired with Sony’s BIONZ XR processor for fast, efficient image processing. The full-frame sensor’s larger light-gathering area, combined with a comparatively lower pixel count, results in larger individual pixels and strong low-light performance, backed by a standard ISO range of 80-102400 for both stills and movies, expandable up to ISO 409600. The camera delivers over 15 stops of dynamic range, well suited to challenging lighting scenarios from bright midday exteriors to dim interiors.
Video capability is central to the FX3’s design, with internal 4K recording at up to 120p and Full HD at up to 240p for high frame rate slow motion, all with 10-bit 4:2:2 color depth using All-Intra or Long-GOP compression across the XAVC HS, XAVC S, and XAVC S-I codec families. For more demanding post-production workflows, 16-bit RAW video can be output over HDMI to a compatible external recorder (such as an Atomos Ninja V), supporting formats like ProRes RAW and Blackmagic RAW, with RAW output resolution reaching 4264 x 2408, beyond DCI 4K. S-Cinetone color science delivers natural skin tones and a cinematic look that matches footage from Sony’s VENICE, FX9, and FX6 cameras, while S-Log3/S-Gamut3.Cine and HLG (Hybrid Log-Gamma) HDR profiles round out the camera’s grading flexibility.
Handling centers on a fast Hybrid Autofocus system carried over from Sony’s a7S III, along with a compact, “cage-free” body design that lets accessories mount directly to the camera without a separate rig, and audio input options including a 3.5mm mic jack, Sony’s Multi Interface (MI) digital shoe for cable-free microphone connection, and a detachable XLR top handle with two balanced XLR/TRS inputs supporting 4-channel 24-bit recording. The camera includes dual CFexpress Type A/SD card slots, dual-band 2.4/5GHz Wi-Fi, and USB-C power delivery for extended shooting sessions.
Build quality is notably compact and lightweight for a full-frame cinema camera, weighing approximately 1.576 lb (715g) with battery and memory cards and measuring just 5.11 x 3.33 x 3.06 inches, with a grip designed in collaboration with professional creators for extended handheld comfort. The FX3 uses Sony’s E-mount lens system, giving it access to Sony’s full range of native full-frame and APS-C E-mount lenses, along with third-party options.
