Ronin S comes with 2 mounting plates; one that attaches to the camera, and then the camera mount screws into the main mounting plate on the gimbal. The problem is that the camera mount needs to be attached to the camera first, and then while holding the camera, two screws need to be screwed into the underside of the gimbal's mounting plate. This little mount was perfect; Two screws were used, just like the original Ronin-S mount. I bought an Arca-Swiss 62mm camera plate and it works great. I no longer need a screwdriver and 3 screws to attach the camera to the gimbal. A must have for Ronin S gimbal users.
