The BIONZ XR™ image-processing engine is designed for high speed, minimising latency while providing impressive real-time processing capabilities. The engine performs real-time processing of AF, image recognition and image quality adjustments, while also handling data transfer, user interface and other camera operations.

High sensitivity, wide dynamic range

The full-frame sensor enables high sensitivity with low noise throughout the camera's range by optimising the sensor’s output. Capture clear motion even in low light conditions with an impressive ISO expanded range up to 409600. It has an extended dynamic range of 15+ stops, without blown highlights. Together, the camera's high sensitivity and wide dynamic range expand your flexibility in post-production.

4K High Frame Rate 120fps recording

You can record full-frame 4K (QFHD) at up to 120fps with autofocus thanks to the high-speed readout capabilities of the image sensor and the powerful BIONZ XR processor. Even at high frame rates, 4K (QFHD) images are captured using full-pixel readout without binning, for clear post-produced slow motion (up to 5x slower than real time). The high-precision AF even allows beautiful full-frame bokeh to be achieved during slow motion shooting.

Acclaimed cinematic colour with S-Cinetone™

The inclusion of Sony’s acclaimed S-Cinetone look, inherited from the development of the FX9, allows cinematic colour to be achieved directly in-camera. S-Cinetone is optimised for natural skin tones and mid-range colours, with gentle highlight roll-off, for impressive subject depiction even without post production grading.  [1] Standard (Picture Profile OFF)  [2] S-Cinetone (Picture Profile 11)

All-Intra internal recording

In addition to Long-GOP inter-frame compression, internal intra-frame (All-Intra) recording is supported. XAVC S-I recording compresses each frame independently at a high bitrate, up to 600Mbps, so is ideal for capturing complex motion, and allowing maximum flexibility and playback performance during post-production.  [1] All-Intra (All-I)  [2] Long-GOP  [3] Group of Pictures

HEVC codec with high compression efficiency

XAVC HS format recording, using the MPEG-H HEVC/H.265 codec, roughly doubles the compression efficiency. Compared to a normal 4K XAVC S format, XAVC HS allows for detailed 10-bit video with 4:2:2 colour sampling at comparable or lower data rates, delivering even better image quality as well as manageable file sizes.

DCI 4K recording in true 24p

The FX3 allows you to shoot in a wide range of formats to suit your shooting needs. You can also select XAVC S-I DCI 4K (4096 x 2160) format which is often used in cinema shooting. And true 24p (24.00p) can be an option for recording frame rate when you selecting XAVC S-I DCI 4K.

16-bit RAW data output

Facilitating improved image quality and more flexible and efficient editing in post production, the FX3 supports 16-bit RAW data output to an external recorder via the HDMI Type-A terminal. RAW video output is from a full-frame image sensor with 4264 x 2408 [16:9] resolution, to suit 4K (QFHD) or DCI-4K workflows, with a choice of frame rates (59.94p/50p/29.97p/25p/23.98p).

New S-Log shooting modes for optimized image quality

Three modes are provided for recording with the S-Log3 gamma curve. Cine EI, used in Sony’s high-end Cinema Line models, offers wide latitude and the highest possible image quality. Eine EI Quick simplifies setup by automatically switching the camera’s base ISO according to the selected Exposure Index (EI). And Flexible ISO provides the greatest flexibility for exposure settings. In addition, Sony’s s709, 709tone, and ITU709 has been added to the available LUT presets.

Proxy recording for more efficient editing workflow

Low bit-rate HD proxy files can be recorded simultaneously with higher bit-rate formats such as XAVC S-I 4K, and these smaller proxy files can then be used for editing and previewing prior to final production delivery. This reduces computer load and allows faster and more efficient workflows. Proxy files can be captured in either 10-bit XAVC HS (1920 x 1080) or 8-bit XAVC S (1280 x 720).

Flexible exposure mode

Flexible Exposure Mode allows the Auto and Manual modes for iris, shutter speed and ISO to be set independently. The lock function, activated by a short press on the respective custom buttons, locks the related controls to prevent changes if the dial or wheel is accidentally moved. The frequently used iris and ISO can be controlled by the easily accessible front and rear dials as well as by the dial on the top panel.

Fast Hybrid AF for dependable focus during movie shooting

Fast Hybrid AF combines focal plane phase-detection AF with contrast-detection AF. This results in highly precise, smooth tracking of fast-moving subjects even over a wide range with a shallow depth of field. AF Transition Speed and AF Subject Shift Sensitivity parameters allow more flexible focus control, as demanded by professional users.

Fast, easy and reliable Real-time Tracking and Eye AF

Focus control is fast and intuitive, to ensure you have full creative control of the FX3’s powerful AF technology. Real-time Tracking greatly assists during solo shooting by analysing the subject's colour, patterns, and depth. When shooting people, Real-time Eye AF makes movie-making much easier, especially with gimbal-mounted shots and wherever you need to rely on AF.

Compensation for focus breathing

With the breathing compensation function turned on, the camera allows you to shoot movies with more stable images when you used with compatible lenses. The breathing metadata can also be recorded so that you can apply compensation with the latest Catalyst Browse/Prepare Plugin software during post-production.

Fast, easy touch focus control

Touch focus control allows you to precisely specify the point of focus simply by touching the LCD monitor. It's fast, easy, and intuitive to perform rack focusing through touch operation—ensuring you have full creative control of the FX3's powerful AF technology.

Uninterrupted 4K 60p recording

For uninterrupted 4K 60p recording, the FX3 features an innovative heat dissipation structure, including a unique Sony Σ (sigma) shaped graphite-alloy heatsink. A complete internal redesign optimised airflow and placement of heatsinks. When required, a silent cooling fan provides ventilation for continuous recording at full resolution, with intake and exhaust air structurally isolated to maintain strong dust and moisture resistance.

Customisable buttons for professional movie creators

The innovative mirrorless design provides mobility alongside uncompromising professional operability. Frequently used controls are positioned on the top surface, and the many customisable keys and menus deliver streamlined workflows in the field. It’s designed for professional results, even when shooting requires one-handed control or challenging shooting angles and lens handling.

Touch-driven menu with workflow-based navigation

Responding to requests from pro photographers and videographers, the menu structure has been designed to make moviemakers’ work more efficient. Menu tabs are on the left side of the display, while parameter groups and parameters related to the selected tab appear on the right. Up to three levels can be displayed together, making the menu structure more clearly visible. Touch-responsive menu operations enable fast, intuitive control.

Two CFexpress Type A-compatible media slots

The camera's two media slots are compatible with CFexpress Type A cards as well as SDXC/SDHC cards supporting UHS-I and UHS-II speed classes. CFexpress Type A cards are the next standard for compact storage with fast write/read speeds suitable for 4K movie recording at high bit rates. Dual slots enable either relay or simultaneous recording.

Reliable, durable, and lightweight construction

For high durability and mobility, the main camera chassis, top, front, and rear covers are constructed from lightweight and robust magnesium alloy, with the lens mount secured by six screws for stable attachment of heavy lenses. A filter in front of the image sensor oscillates at an ultrasonic frequency of 70,000 cycles per second to remove dust from the sensor surface.

Reliable durability and weather resistance in tough situations

In response to feedback from working professionals, sealing has been applied to all body seams and around the battery and media compartments, terminal covers and chassis joints. All routes for dust and moisture entry have been examined to ensure reliable operation in challenging environments.
