DJI, the first 4-axis 8K/6K cinema camera "Ronin4D"-AV Watch

DJIは、フルサイズセンサー搭載Zenmuse X9ジンバルカメラ、4軸安定化機構、LiDARフォーカスシステム、映像伝送&制御システム等を統合した撮影システム「」を発表。ラインナップと価格は6K対応カメラがセットの「6Kコンボ」が869,000円、8K対応カメラの「8Kコンボ」が1,320,000円。6Kコンボは12月発売で、8Kコンボは発売日未定。

Equipped with full-size sensors, the Zenmuse X9 gimbal camera is equipped with "X9-8K" and "X9-6K" to achieve cinema quality image shooting. In addition to the commonly used H.264 codec, both models can be included internally in Apple ProRes and ProRes RAW, and the scope of post-processing editing is expanded.

The X9-6K supports maximum 6K/60fps and 4K/120fps shooting, while the X9-8K supports maximum 8K/75fps shooting, providing multiple options to capture cinema quality images.

Develop the most powerful film imaging system in the history of DJI. The self-developed flagship chipset implements the intelligent image processing system CineCore3.0, which supports the internal inclusion of 8K RAW codecs with correct color reproducibility, advanced auxiliary functions of high-performance AI engine, confirmation and control on multiple monitors through low-delay image transmission.

Using the 800Rab 5000 dual native EI or 14 to stop the above dynamic range, you can shoot impressive images in rich tones in any shooting scene. It is reported that it is equipped with its own DJI cinema color system (DCCS), which can reproduce the natural skin tone even in a complex lighting environment.

Even when using a cinema camera other than X9, you can maintain a consistent hue through the project. It is said that through the 9 stop ND filter built into the camera, it is easy to adjust even in an environment where the brightness state changes (especially outdoor shooting).

The lens installation of the X9 is replaceable, DJI's own DL installation, Leica M installation, and other flange backs can be installed for short installations. As a result, image producers can use ultra-wide-angle lenses, deformable lenses, retro manual lenses, etc., and can take pictures in an imaginary style.

The Z axis is added to the traditional three-axis universal joint to effectively and actively eliminate the vertical camera sloshing. With this technology, which is pioneered in the industry, you can shoot stable videos when walking, running, or even walking violently, without having to practice the way you walk and install other equipment.

Even in places where it is difficult to shoot video, such as stairs and irregular floors, smooth images can be taken without being shocked by the photographer's walking. In addition, you can do a wide range of slider photography without using Dolly.

Based on DJI's experience in stabilization technology in aerial photography and handheld products, advanced algorithms are used to process input information such as lower ToF sensors, front and lower dual vision sensors, built-in IMU, barometers, etc., to achieve unprecedented smooth image shooting.

Although the Z axis is added this time, compared with many movie cameras installed on professional three-axis stabilizers, it is characterized by light weight and miniaturization.

ActiveTrack Pro uses DJI's unique technology to easily and efficiently carry out complex and highly tracked. Based on DJI's existing ActiveTrack technology, this Pro version uses the latest AI technology to track distant subjects while adjusting the position of subjects in the frame to maintain the best shot.

The newly designed LiDAR rangefinder can continuously carry out accurate laser measurement and adjust the focus accurately and quickly. Up to 43200 ranging points can be detected at the same time in a range of up to 10 meters, and the position of the subject can be captured quickly and accurately even in low illumination environment.

The LiDAR can measure the distance of the subject without being affected by the pattern on the surface of the subject or causing oscillation, so the focus adjustment can be performed without sacrificing the image quality.

There are three focus adjustment modes: manual focus, Auto focus and DJI's unique Auto Manual focus (AMF).

In manual focusing, using the LiDAR waveform as an auxiliary focusing tool, the photographer can grasp the focus position and draw the focus.

Autofocus is to automatically adjust the focus in the unpredictable circumstances such as the dynamic movement of the subject, such as documentary shooting, and continue to capture the subject sharply.

The automatic manual focusing mode combines the advantages of manual focusing and autofocusing. According to the change of the focus position, the focus wheel is automatically rotated to adjust the focus, and the photographer can focus manually and intuitively at any time.

With refreshed DJI's O3 Pro transmission technology, the 4D video transmitter transmits 1080p/60fps video to a remote monitor within a maximum range of about 20000 feet (4 km in Japan). At the same time, it supports AES256-bit encryption technology to achieve secure and low-delay transmission. In order to confirm the monitor smoothly in real time, the photographer can move freely within the photography group.

In addition to the 2.4GHz and 5.8GHz bands, O3 Pro also supports the DFS (dynamic Frequency selection) band. Even in the signal crowded environment and complex building structure, it also shows stability and anti-interference. In this system, a transmitter supports simultaneous connection of multiple receivers. In addition, even if you use multiple Ronin 4D, you can switch images immediately.

The high brightness remote monitor integrates the wireless video receiver into the 1500 nit and Type 7 monitors. The monitor has a built-in gyroscope sensor, which can be used as a motion controller and can be controlled by the camera according to the action.

You can also connect Ronin4D handles, DJI Master Wheels, DJI Force Pro, and emerging DJI3ch Follow Focus. In the case of multiple remote monitors, using a separate LUT in each device can confirm the image material separately without interfering with other monitors. The monitor has built-in microSD card slot. Support for proxy video recording up to 1080p/60fps.

There are three methods of recording. In addition to the cost-effective USB SSD in 4K images and the CFexpress Type- B card with compatibility and stability, PROSSD1TB developed by DJI can also be used. PROSSD1TB can perform internal recording at maximum resolution and frame rate for excellent performance and stability.

In voice recording, there is a built-in microphone that supports dual-channel 24-bit audio. In addition, as an additional input and output option, the body is equipped with a microphone input and headphone output 3.5mm Jack, and the expansion board is equipped with two XLR ports.

Like Ronin2 and Inspire2, the battery uses TB50 smart battery. The maximum continuous shooting time is 2.5 hours. It is assumed that the battery has the function of spontaneous heating and has excellent durability even in harsh environments.

In addition to the camera body, it also includes a LiDAR viewfinder, a high-brightness main monitor, a handle, a top handle, a TB50 smart battery and a suitcase. PROSSD 1TB is also added to the 8K combination.
