The PXW-FX9 input and output features include 12G/6G-SDI and HDMI outputs for 4K video, a 3G-SDI output for HD, and genlock and timecode when using a multicamera setup. The Fast hybri AF autofocus system allows for accurate focus and even allows facial detection to automatically detect human form with 561 points of detection. Advanced image stabilization is achieved using the PXW-FX9's internal gyroscope for shots so smooth it'll look like you used a gimbal. Its 4-channel audio recording allows you to use external microphones and record ambient sound with the internal mics simultaneously.
Firmware Version 4.0
C3 Portal Integration Improvements:

• LUT  improvements include the ability to import and manage 3D LUT files created in the cloud.
• Multiple camera ALL files can be managed via the cloud service.
• Automatic file transfer: Original files can be backed up to the cloud after capturing each clip, eliminating the need to block out time to create backups.

Shooting Workflow Improvements:

• Record LUT Data as Metadata: LUT cube data applied to your monitor image can now be recorded as metadata, saving time in post otherwise spent managing LUT data linkage.
• Audio Meter Channel Switching: You can now switch the onscreen audio level meter between CH1/2 and CH3/4 using the Audio menu.

6K CMOS Exmor R Sensor
The PXW-FX9's oversampled full-frame 6K sensor provides recording in DCI 4K, UHD, and HD resolutions. Powerful image processing with debayering and down-sampling ensures image quality beyond the limits of conventional Super 35mm sensors. The back-illuminated CMOS image sensor also uses Sony's Exmor R technology for improved sensitivity and noise reduction. Compared to a 4K Super 35mm sensor, the FX9's 6K sensor has over twice the surface area while providing a wider angle of view and shallower depth of field.
