Camera Overview — Sony FX9

The Sony FX9 is a full-frame cinema camera built around a 20.5-megapixel sensor (19 MP effective) with an advanced image processor featuring debayering and down-sampling. The sensor captures in 6K with DCI 4K output, and the camera supports internal 10-bit 4:2:2 recording as well as 16-bit RAW external output — a meaningful combination for cinematographers who need flexibility in both on-set monitoring and post-production workflows. Frame rate options span from 24fps up to 120fps, covering a wide range of cinematic and slow-motion needs.

Color science includes S-Cinetone, S-Log3, HLG (Hybrid Log Gamma), and support for User 3D LUTs, giving colorists multiple starting points depending on the project. The autofocus system combines Phase Detection, Contrast Detection, Eye Detection AF, and AI-Based Subject Tracking across 561 focus points — a serious asset when shooting run-and-gun or documentary content. The body is constructed from a magnesium alloy and polycarbonate composite, measures 146 x 142.5 x 239 mm, weighs 2 kg, and carries a weather-sealed rating.

A 3.5-inch fully articulated LCD with 2.76 million dots and a removable OLED EVF with matching resolution and a 60Hz refresh rate round out the monitoring setup. Connectivity includes Full HDMI Type A with 4K capability, Wi-Fi, a USB port, and both 3.5mm headphone and microphone jacks. Storage is handled via XQD, SDXC, or Memory Stick slots.

Key Features — Sony FX9

Full-Frame ~20.5MP Sensor: A 35mm full-frame sensor with oversampled 4K output gives cinematographers wide field of view and high-resolution source material for cropping and reframing in post.

10-Bit 4:2:2 Internal Recording: Records 10-bit 4:2:2 footage internally, providing substantial color data for grading without requiring an external recorder.

16-Bit RAW External Output: Outputs 16-bit RAW to compatible external recorders, giving colorists maximum dynamic range and latitude in post-production.

4K 60fps / 1080p 120fps Slow Motion: Shoots up to 120fps at lower resolutions, enabling high-quality slow-motion footage alongside standard cinema and broadcast frame rates from 24fps to 60fps.

561-Point Hybrid Autofocus: Combines Phase Detection, Contrast Detection, Eye Detection AF, and AI-Based Subject Tracking across 561 points — practical for documentary, run-and-gun, and single-operator shoots.

S-Cinetone & S-Log3 Color Profiles: Supports S-Cinetone, S-Log3, HLG, and User 3D LUTs, giving colorists multiple starting points to match different project and delivery requirements.
