DJI has unveiled Ronin 4D, a cinema camera system with a built-in four-axis gimbal, 8K resolution, and a Lidar rangefinder that promises "sharper, faster and more reliable focus".
Starting at $7,199, it's aimed at professionals, but also showcases DJI's technological prowess in gimbal and camera technology.
The "Zenmuse X9" camera was designed specifically for Ronin 4D and should be given pause by dedicated camera manufacturers.
It's a full-frame interchangeable camera that can use DJI's DL or Leica M lenses (as well as other mirrorless lenses via adapters) and comes with no fewer than nine built-in neutral density (ND) filters to control exposure.
DJI said in a press release that the lidar focusing system provides "43,200 ranging points up to 10 meters to quickly and accurately locate targets even in low-light environments."
The statement didn't mention the camera's other auto-focus technology, though it "supports face/body recognition and framing of any object."
It also notes that the system "measures the distance to an object without relying on surface texture or looking for edges," meaning it does not use contrast to detect AF.
The system supports fully automatic focus, manual focus, and "automatic manual focus" (AMF), allowing camera operators to "zoom with extreme precision."
The general idea of the AMF is that autofocus handles most AF chores, but allows operators to manually intervene at any point.
Other features include a long term (20,000 ft) video transmitter output 1080/60p feed remote monitoring, three storage methods (USB SSD, CFexpress B, and close proprietary PRO SSD 1 TB), built-in microphone 3.5mm microphone port, and XLR port through an expansion board and battery for 2.5 hours of shooting time.
The Ronin 4D with a 6K camera costs $7,199 and the 8K model costs $11,499.Both come with a gimbal, camera, lidar rangefinder, display, handle, top handle, carrying case, and battery.
Sure, that's a lot, but less than some movie camera systems themselves -- and DJI's Ronin 2 movie theater stabilizer ran more than $8,000 without any cameras.
