We called DJI's DSLR and mirrorless Ronin S gimbal "essential YouTube equipment," and it just got even more so with nine new accessories. The most interesting for filmmakers is the $169 Focus Motor for manual focus lenses. It consists of a motor, rod mount set and focus gear strip that can handle a wide variety of lens diameters. Once attached and connected to the Ronin-S, you can can use the existing the $59 Focus Wheel to adjust manual focus with .02 degrees of accuracy.
If you'd rather not use your smartphone to control the Ronin S, DJI has introduced the $129 Command Unit that attaches to the side. It has a small screen that lets you quickly change settings like motor controls and operations. There's also a new $69 External GPS Module that improves stability when you do quick moves that rapidly accelerate the gimbal. It also helps keep the horizon line horizontal.
