The Sony FX3 is a compact, weather-sealed full-frame E-mount cinema camera with a 12.1 MP Exmor R CMOS sensor, 4K recording, 5-axis in-body stabilization, and a vari-angle 3.0-inch touchscreen.
The review concludes that the FX3 delivers a great image, is easy to use, and offers excellent options for on-the-go shooters, essentially functioning as an A7S III with a handle. The author notes a desire for built-in ND filters, higher resolution, and additional mounting points.
The review describes the camera as one of the safest compact cinema buys for solo filmmakers and documentary shooters, praising its 4K 120p, autofocus, low-light performance, and active cooling. It cautions that it is not ideal for those needing built-in ND filters or high-resolution stills.
The author positions the FX3 as a specialist tool that is nearly unbeatable at its price point for videographers building a dedicated production rig, highlighting its superior rigging flexibility and ergonomics compared to the A7S III.
This review highlights the camera's ability to combine the performance of the Alpha 7S line with cinema-oriented features like an XLR handle and 4K 120fps recording, noting it as a freedom-giving, compact powerhouse for professionals.
