At the heart of the Sony FX5 lies the new, fully stacked Exmor RS CMOS full-frame 16.6 MP (5K) sensor, which offers exceptionally fast data readout and minimizes the rolling shutter effect. Combined with the next-generation BIONZ XR2 processor and the dedicated AI processing unit, the camera delivers top-tier autofocus with advanced subject recognition (people, animals, birds) and automatic white balance adjustment. Additionally, it features three base ISO values (800 / 4000 / 12800) with Dual Gain option, ensuring an impressive 16+ stop dynamic range for clear shots even in the most demanding low-light environments.

The camera borrows the compact and ergonomic body of the popular FX3, upgrading control with a renewed user interface and the specialized cinematic BIG 6 menu. The large 3.5" LCD touchscreen (16:9) features a 4-axis adjustment mechanism for comfortable framing from any angle. Additionally, it incorporates professional monitoring tools such as false colors, waveform, vectorscope, focus map, and an internal anamorphic desqueeze function, while also supporting the optional DVF-EL1 electronic viewfinder.
