The FX3 features a 10.2MP Full-frame Backside-illuminated (BSI) Exmor R CMOS sensor that delivers sensitivity, speed and superior movie quality. The sensor features a color filter array that boosts color reproduction accuracy while delivering up to 15+ stops of dynamic range3 and drastically reduced noise for ultra-sharp and clean images with a fast readout speed that reduces rolling shutter. In addition, the Exmor R sensor features Sony's acclaimed fast hybrid autofocus with 627 phase detection AF points and 89% coverage. The high sensitivity also allows it to autofocus in light as low as EV-6.

In response to a growing need for more expressive depth, the FX3, along with FX9 and FX6 Cinema Line cameras, allows users to easily create a cinematic look without post-production using S-Cinetone picture profile. Inspired by the color science used in Sony's flagship VENICE camera, S-Cinetone delivers natural mid-tones, plus soft colors and gorgeous highlights that are essential to cinematic expression. S-Cinetone is the default for Picture Profile 11 (PP11) on the FX3.

An easily manageable compact body that doesn't get in the way translates directly into increased workflow efficiency and shooting freedom for creators involved in video production. The FX3 is designed to eliminate the need for a camera cage, including six standard ¼"-20 UNC threaded mounting points to easily and securely attach compatible accessories such as external monitors, recorders, wireless microphones, or other add-ons. In addition, the supplied top handle with XLR interface securely attaches to the body via the Multi Interface Shoe without any special tools and provides three additional thread holes. Since no cage is required, the system size and weight is reduced making transporting easier and setup time quicker. The FX3 has everything a single operator needs for video production in a versatile, easy-to-use compact and lightweight package that can be expanded to meet growing needs.

The FX3 features the same BIONZ XR system architecture as the FX6, with high processing performance from image capture through all signal processing stages. User interface, network, and file management processing is distributed so that fast, stress-free control response is maintained regardless of real-time processing load. The engine also makes it possible to deliver high sensitivity and natural gradations, realistic color reproduction, low noise, and other image quality improvements as well as faster, more precise AF plus the ability to process the large amounts of data required for 4K 120p 10-bit 4:2:2 recording. It also features improved menu response and high-speed write to CFexpress Type Amemory cards.
