Sony is expanding its FX Cinema Line with a new compact model, the FX3. Its design language is inspired by the Alpha mirrorless camera series with which it shares a lens system, while its video capabilities are closer to the FX6 and FX9. The slimmer form factor lends itself better to location, documentary, and aerial work.
Built Tough for Field Use
The FX3 isn't too far off from the top-line video camera in the Alpha series, the a7S III, in shape and size. The a7S III is more of a hybrid, so it includes an integrated viewfinder. Cinematographers are more likely to rely on external displays or the built-in LCD, so it's absent here.
That makes the FX3 a bit flatter on top, and its silver finish further sets it apart from the a7S family. The body is magnesium alloy and, like many compatible lenses, is protected from dust and splashes, useful for location work. The FX3 seems like a very good match for Sony's forthcoming Airpeak cinema drone.
It includes a handgrip, styled after still cameras, that houses the Z series battery. Thread mounts are on the top, bottom, and sides, so you won't have to use a mounting cage. For stable low-angle shots you can use the included XLR handle—it mounts to the top and adds support for 24-bit, 4-channel audio capture.
The built-in LCD is a vari-angle design. It swings to the side and tilts to face forward, up, or down. It supports touch input, so you can tap to set a target for autofocus.
Tally lights on the front, rear, and top are included, as is an active cooling fan. Sony promises that the camera can record continuously at 4K60 without overheating. It also supports 4K at 120fps, though.
Internal recording is available at 10-bit 4:2:2 quality to CFexpress (Type A) and SDXC media—there are two memory card slots, each supporting both card types. The full-size HDMI connection outputs 16-bit footage without compression, so you can leverage Raw recording with the aid of an external recording device.
Stabilized Full-Frame Sensor
The FX3 uses a full-frame sensor made just for video. Its 10.2MP resolution is ideal for recording at 4K, and you've got freedom to work sans gimbal thanks to a 5-axis stabilization system and digital assistance. Sony's editing software leverages motion data from the camera to effectively steady footage in post.
Manual focus is an option, but Sony is touting the FX3's autofocus capabilities too. Cinematographers can concentrate on composition, rather than pulling focus manually. The FX3's autofocus system covers all but the very edges of the frame and supports subject tracking, face and eye detection, and adjustable rack speed.
There are a number of color profiles available, including the Cinetone-S look developed for Sony's Venice camera system. You can use it to get footage ready to share without color grading, or rely on a flat S-Log profile for a bit more creative freedom when applying color adjustments. Sony promises that the camera can capture more than 15 stops of dynamic range. Its image sensor can be set as low as ISO 80 and as high as ISO 409600. The high ISO capability is especially appealing for working in low light.
Pricing and Availability
The FX3 starts shipping in March for $3,900 as a body only for US customers and at $5,000 in Canada.
