Use the Multi-Camera Control Cable (Multi-USB) to connect your Sony camera to the Ronin-S Camera Control Port. The Ronin-S Camera Control Button can be used to control the shutter, autofocus and recording process. The optical zoom can be controlled through the Ronin-S Focus Wheel (only applicable for lenses with a built-in power zoom, such as the Sony E PZ 18-105mm F4 G OSS). If a power zoom lens is not mounted, the Focus Wheel will control the digital zoom. Digital zoom must be enabled in your camera’s settings.
