DJI Ronin 4D offers a completely unique design. Crafted with carbon fiber and aluminum magnesium, its solid body integrates the imaging, stabilization, and focusing systems, as well as wireless transmission and control. This avoids time-consuming setup and enables quicker shooting.
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 compact cinema camera. CineCore 3.0 allows Ronin 4D to support internal recording of Apple ProRes RAW, 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.
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.
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 180 g. More DJI lenses will be available in the future.
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.
The 6K version of the DJI Ronin 4D will be available for £6000 in December 2021. It will includes the main body, a Zenmuse X9–6K gimbal camera, a LiDAR Range Finder, a High-Bright Main Monitor, Hand Grips, a Top Handle, TB50 Intelligent Battery and a carrying case. The 8K version of the DJI Ronin 4D will be available at a later date and will include the Zenmuse X9–8K Gimbal Camera as well as a PROSSD 1TB. The 4D Video Transmitter, High-Bright Remote Monitor and DJI PROSSD 1TB will also be available to purchase separately.
The weight of this beast less lens is 5KG, I think this should see its way into a specialist rental market as its far to specialised and quirky for someone to own.
