The Teaching + Learning Centre’s ECUPS unit will begin using the DJI Ronin-M Handheld Gimbal with Remote and Sony A7R III DSLR Camera for film productions in the Fall of 2018.
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 105⁰ up / 165⁰ down plus a roll range of ±110⁰. 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-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 12V DC PowerTaps 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 regime and avoid unnecessary added weight.

The Sony a7R Mark III is a full-frame mirrorless camera that uses a 42.4MP stabilized BSI CMOS sensor. The Mark III has numerous improvements over its predecessor, many of which are borrowed from the flagship a9. Faster processing and a redesigned shutter allow for 10 fps bursts (or 8 fps with no viewfinder blackout), and a refined autofocus system promises better subject tracking performance. The design hasn’t changed much, with the main additions being a higher resolution EVF, joystick for adjusting the focus point, dual SD card slots and a higher capacity battery. Video can be captured at UHD 4K (30p) using the full-width of the sensor or a Super 35 crop, and 1080/120p option is also available. The a7R III supports S-Log3 and Hybrid Log Gamma profiles, among others.
