DJI Ronin 4D Flex enables more flexibility and stabilization in filming

Ronin 4D Flex is compatible with the Ronin 4D ecosystem, so you can use it next to the handles and dedicated monitor of the original set. It is also possible to shoot with the kit, as it supports a wide variety of telephoto, cinematographic and anamorphic lenses, including dji's new DL PZ 17-28mm T3.0.

Notes

  • 1. Measured when 6K Combo is fully set up with the main monitor attached and the Z-Axis off.
  • 2. Measured with a fully charged TB50 Battery and Ronin 4D in a still state with the gimbal balanced, the Z-Axis inactive, and continuously recording in RAW. Gimbal movements or use of the Z-Axis will reduce operating time.
  • 3. Autofocus on manual lenses requires DJI Zenmuse X9 Focus Motor.
  • 4. Supported through a future firmware update.
  • 5. Please use recommended CFexpress cards.
  • 6. Please use recommended USB-C SSD.
  • 7. Stabilization range of the Z-Axis is subject to change based on Z-Axis modes and usage scenarios and may be smaller than the mechanical range.
  • 8. Unobstructed, free of interference.
  • 9. 100ms is measured at 4K/24fps, 68ms is measured at 4K/60fps.
  • 10. Some frequency bands may not be available depending on the legal policies of the region the monitor was activated in.
  • 11. Supports HDMI 2.0.
  • 12. Measured at 50% screen brightness with DJI WB37 battery.
  • 13. Supports HDMI 1.4.
