The
Ronin-M 3-Axis Handheld Gimbal Stabilizer
from
DJI
is a camera stabilization system designed to give the operator close to the freedom of unencumbered handheld shooting but without the hand-shake. Suitable for most camera types and configurations up to 8 pounds, the Ronin-M uses brushless motors that work on three axes: one for side-to-side "roll" (keeping the horizon level), one for tilt, and one for pan. The system is computer-controlled and features a tilt range of 105° up / 165° down plus a roll range of ±110°. Furthermore, the system boasts a precision of control of ±0.02°, enabling precise camera moves and stability correction against even very fine movements. In addition to handheld shooting, the gimbal can be used in vehicle mounting scenarios and other contexts where vibrations or other abrupt movements would make tripods and rigid camera support systems unsuitable.
The Ronin-M supports dual-operator shooting, much like working with a jib that has a motorized pan/tilt head. In this mode, a second operator would use the included transmitter (radio controller) to manually control camera pan and tilt independently of which way the Ronin-M itself moves. The included transmitter/receiver system operates on 2.4 GHz and is proprietary. If you prefer to use a third-party transmitter there is a D-Bus port on the Ronin-M to install your own receiver.
As with sled and vest style stabilizers, motorized gimbal systems require balancing before use. Once balanced, you can configure the Ronin-M for your particular camera arrangement using the Assistant Software for compatible iOS and Windows (Desktop) devices with Bluetooth. Because every camera and lens combination has a different mass and weight distribution, there is an ATS (Auto Tune Stability) procedure in which each axis will adjust individually, repeating the process until all three are aligned. A gimbal tuning stand is provided so you won't have to hand-hold the rig during this process.
The included 4S lithium-ion polymer battery powers the Ronin-M for up to six hours. It is a "smart" battery, meaning power regulation and protection circuitry is built-in and there is no separate balancing lead, unlike many lithium-polymer batteries. A charger is also included, and it is important to always use chargers designed for the Ronin-M battery because of the smart circuitry. Two 12 VDC D-Tap ports and one USB power port on the camera base allow you to power on-camera accessories directly from the Ronin-M battery to simplify your charging regimen and avoid unnecessary added weight.
For Cameras up to 8 lb
The Auto Configuration feature means the Ronin-M can adapt to a range of camera sizes, and is ideally suited for compact video cameras, mirrorless cameras, and DSLRs. It is suitable for payloads up to 8 pounds.
SmoothTrack Control
SmoothTrack gives a single gimbal operator the ability to translate their tilt and pan movements of the gimbal into smooth and stabilized movements of the camera's angle. This is designed to make framing of broad wide-angle scenes or even shooting in close quarters much easier during single gimbal operator use.
Auto Configuration
After balancing the camera with a simple tap of the ATS (Auto Tune Stability) button, Ronin-M will be automatically tuned for the mass and weight distribution of your camera rig. The gimbal will intelligently adjust parameters based on the camera rig's weight and independently adjust each of the three axes until an optimal setting is found.
Three Operation Modes
Upright Operation Mode
: Upright Mode allows the gimbal to be flipped over so the camera can be operated closer to eye level without straining to lift the gimbal. This can be used in various situations, such mounting on the top of the vehicle.
Underslung (Suspended) Operation Mode
: Suspended Operation Mode is the standard operation mode for Ronin-M. Low slung, close to the ground, or simply holding the gimbal in front of you offers stabilized handheld footage. This mode would also be used when mounted the gimbal on a flying platform such as a multirotor RC helicopter.
Briefcase Mode
: When a slimmer gimbal profile is needed in situations like moving through doorways or narrow paths Briefcase Mode is ideal. It allows the gimbal to be held to the side and close to the legs, much like a briefcase.
Second Operator Control
Featuring the form factor of an RC aircraft radio controller, the 2.4 GHz Ronin transmitter provides pan and tilt control as well user-assignable speed settings and operation modes via two toggle switches. This allows one operator to hold the gimbal assembly while a second manually controls camera movement remotely. If you would rather use a third-party transmitter a D-bus port is provided as well.
Optional Thumb Controller for Pan / Tilt
Single thumb control is possible for the Ronin-M Handheld Gimbal System. These Pan and Tilt movements are controlled via the optional Thumb Controller attachment, available separately. Additionally, SmoothTrack Mode can be turned on or off using the Thumb Controller interface.
Assistant Software for Mobile and Windows
A mobile device or computer to run the Assistant Software is essential. It is available for select iOS mobile devices and Windows computers. With the software, you can:
Auto Configure the rig based on the weight and weight distribution of your camera after you've balanced it
Adjust SmoothTrack tuning to user preference
Enable and configure Second Operator Control
Run diagnostics and generate stats
Install firmware updates
The software can interface via USB or wirelessly over Bluetooth.
Tool-Free Adjustment
A built-in balance adjustment system means no tools are needed for setup and adjustment, saving time when changing the setup for different camera arrangements.
Universal Mounting
Beside the handle bars, the gimbal unit can be detached for mounting on jibs, cranes, tripods, vehicle mounts, and other types of camera support equipment (additional mounting hardware, available separately, may be required).
Solid Support Arm
Increased rigidity is provided by a single, complete piece of fine-tooled magnesium that forms the U-shaped arm holding the camera plate. This unified design helps eliminate imperfection common in systems made of multiple pieces assembled together. The arm gives you not only greater stability but also reliability, as there is no potential for separate pieces to come loose or move apart.
Silent Mode
When shooting indoors or in tight spaces, Silent Mode reduces the sound of each motor as low as possible. The Ronin-M's stabilization algorithms are updated to focus on minute changes and stabilization, helping ensure the sound of the motors is not recorded by sensitive microphones or other recording equipment.
Quick Release Smart Battery
Providing an estimated 6 hours of run time (depending on use), the proprietary Ronin-M battery system is designed for easy changes in the field and charges using an included dedicated charger. The batteries feature indicators so remaining power can be checked directly on the battery itself. Unlike many lithium-polymer batteries, with the Ronin-M Smart Battery, overcharge and over depletion protection is built-in, as is individual battery cell charge balancing.
Power Distribution Box
Two regulated 12 VDC D-Tap ports, one 500mAh type A female USB connector, and also a connection point for the DJI Lightbridge Long Range HD Video Downlink are provided. These provide power connection for various accessories, including motorized follow focus systems, video transmitters, and more, all while keeping the wiring to a minimum.
Quick Release Top Handle
The quick-release handle is designed to save time breaking the system down or transporting it between locations. Removing the handle bars can also be useful as a way of reducing size when filming in tight locations.
Based on Zenmuse Technology
The Ronin-M adapts the same brushless motor technology used in DJI's aerial gimbals for handheld, terrestrial use.
