Processing Power

Ronin 4D is equipped with Zenmuse X9, DJI’s flagship full-frame camera. It also features DJI’s latest image processing system, CineCore 3.0. This system uses DJI’s proprietary chip to provide advanced processor architecture, offering extremely high-performance computing power in a cinema camera today. CineCore 3.0 allows Ronin 4D to support internal recording of Apple ProRes 4444, ProRes 422 HQ, and H.264 video. It also supports up to 8K/75fps and 4K/120fps video recording, delivering multiple options for professional-level creation.

Resolution

DCI 6K (6008×3168)/48fps video retains every little detail, from rich foliage to inspiring architecture, skin texture to strands of hair, all with flawless quality. For those who need to output in 4K, recording in 6K offers unprecedented creative options with more flexibility for cropping, re-composing, and stabilizing videos in post.

High ISO 

Zenmuse X9 supports dual native ISO (X9-6K: 800/5000), which records images with exquisite detail and minimal noise, even when filming an evening cityscape or beach, or a scene lit by dim candlelight.

Dynamic Range 

With 14+ stops of dynamic range, Zenmuse X9 delivers natural transitions of highlights and shadows in complex lighting conditions such as backlit scenes and direct sunlight. These traditionally difficult scenes can now be captured easily and with confidence.

Color Science

With the DJI Cinema Color System (DCCS) and robust computing power provided by CineCore 3.0, Zenmuse X9 is able to give images a cinematic look by retaining authentic and accurate colors. It also supports the industry-standard ACES workflow for effortless compatibility with the color tones of other cinema cameras.

Built-In 9-Stop ND Filters

X9 has 9-stop built-in high-quality ND filters (ND 2 to ND 512, or ND 0.3 to ND 2.7) that can be quickly and easily switched thanks to an internal motorized system. These filters were also designed to match and compliment the color science of Ronin 4D. 

DL Lenses

X9’s standard DL mount supports three compact full-frame prime lenses. The housings are made of lightweight, monocoque carbon fiber, so each lens weighs just about 180 g. More DJI lenses will be available in the future.

Interchangeable Mounts

X9 supports interchangeable lens mounts, including DJI’s proprietary DL mount as well as third-party mounts like Leica M. Ultra-wide, f/0.95 large-aperture, electronic zoom, macro, and anamorphic lenses that are compatible with traditional cinema cameras also work on X9, providing flexible lens options.

Wireless Control

Whether you’re using manual or autofocus lenses, dedicated modules mounted to X9 can achieve wireless lens control and even autofocusing.

4-Axis Stabilization

DJI Ronin 4D adds a Z-axis to the traditional 3-axis gimbal, which effectively decreases vertical camera shake and offers stabilization performance on par with a dolly. The four axes work together with a downward ToF sensor, forward and downward dual-visual sensors, a built-in IMU and barometer, and an advanced new algorithm to bring the overall stabilization to a whole new level.

When this compact body combines with its powerful stabilization capabilities, complex camera movements that used to be very costly to achieve are now easily attainable.

Integrated Gimbal Camera

Ronin 4D integrates the imaging and stabilization systems while keeping only the sensor and necessary optical components in the gimbal camera. The tilt axis of the gimbal uses dual symmetric motors, whereas both the pan axis and the roll axis are designed with an additional stiffness buffer.

The compact and portable gimbal system allows shooting to begin without the need for tedious manual balancing. This also delivers stable footage, even with lenses that have a shifting center of gravity during use.

With a highly integrated body and robust motor force, Ronin 4D offers the best stabilizing and tracking performance of the entire Ronin Series so far at an incredibly light weight. Additionally, it can switch to Sport mode with the press of a button, allowing the gimbal to react quickly to the cinematographer's movements.

It also supports wireless gimbal control and versatile mounting configurations for varied shooting scenarios.

ActiveTrack Pro

DJI’s proprietary computer vision, deep learning technology, and the robust computing power of CineCore 3.0 combine in ActiveTrack Pro, which enables cinema-standard tracking shots, even in just one take. This technology also allows subjects to be tracked from longer distances and features composition adjustment with continuous autofocusing to keep subjects in focus during tracking shots.

LiDAR Waveform

DJI Ronin 4D makes manual focusing easier than ever. The visualized focus assistance technology displays the ranging points on the main and remote monitors in a simplified top-down view. This provides an innovative and intuitive LiDAR Waveform to locate focus points quickly and allow focus adjustments with extreme precision. Even operators with little or no experience can become adept at manual focusing quickly.

LiDAR Range Measurement

The LiDAR Range Finder can cast up to 43,200 ranging points within a 10-meter detection range. Compared with phase detection autofocus (PDAF), Ronin 4D’s LiDAR Focusing System can focus faster, without compromising the image quality or relying on the surface texture of the subject. This is especially useful in low-light environments and results in exceptional focusing capabilities compared to other cinema cameras. 

Autofocus

With the new LiDAR Focusing System, Ronin 4D is able to maintain focus even when there is severe motion blur caused by subjects moving quickly. With the focus motor mounted, autofocus is available even on manual lenses. Continuous autofocusing on subjects can be enabled together with ActiveTrack Pro, making it especially convenient for solo operators.

Automated Manual Focus

Automated Manual Focus (AMF) mode gives you the accuracy and flexibility of manual focus with the convenience of autofocus. The focus wheel will rotate in sync as the focus point changes, but cinematographers can take manual control at any point. The focus wheel on the right hand grip even features dynamic damping with electromagnetic technology. This gives cinematographers a physical sense of focus changes, providing a more intuitive and modern focusing experience that is unrivaled in the industry today.

Video Transmission Performance

Ronin 4D uses the all-new DJI O3 Pro Video Transmission technology, which offers a 20,000-foot transmission range that would be unimaginable on traditional solutions. In addition to 2.4GHz and 5.8GHz, it supports the DFS frequency band and an AES 256-bit encryption algorithm that can output a 1080p/60fps FHD feed to multiple remote monitors simultaneously with significantly enhanced security, stability, and anti-interference capability.

DJI's proprietary chip powers the imaging system, video transmitter, video receiver, and remote monitor of Ronin 4D. Together, these components form a streamlined wireless transmission system, with every link explicitly optimized to provide end-to-end ultra-low transmission latency.
Integrated Design
The 4D Video Transmitter can be directly mounted onto Ronin 4D and powered by the battery of the main body. With a built-in wireless video receiver, the High-Bright Remote Monitor has a 7-inch, 1,500-nit high-bright, wide color gamut touchscreen display that can output both HDMI and SDI signals through the expansion module. Its compact and lightweight body provides optimum portability and efficient setup so users can start shooting immediately.

Coordinated Shooting

The High-Bright Remote Monitor supports one transmitter with multiple receivers for video and audio feeds. Two transmission modes are available. The first is Broadcast mode, which sets no limit on the number of receivers and is suitable for monitoring with large crews. The second is Control mode, which supports the coordinated operation of two receivers.

The High-Bright Remote Monitor can connect to the Hand Grips of Ronin 4D, DJI Master Wheels, DJI Force Pro, or the new DJI Three-Channel Follow Focus. This enables remote control of focus and gimbal movements with high precision, starting and stopping of recording, and camera setting adjustments to meet the highest standards of coordinated shooting on sets. In addition, the built-in gyro sensor turns the monitor into a remote motion controller for the gimbal of Ronin 4D.
