Sony's RM-30BP Remote Controller features a compact form and can control most of the functions of your compatible NX5R or FS7 (v4.0) camera. The remote enables control of the one-push auto, manual focus, iris, and zoom of your lens. It also allows you to control the recording/display functions of your camera, as well as shutter speed and white balance adjustment.
You can assign six buttons on the controller and control the functions and playback of up to three cameras, individually or simultaneously. The remote incorporates an adjustment knob that can be set to control your camera's focus, iris, or electronic ND selection (if your camera features electronic ND). At the bottom of the unit is a zoom rocker with protective bar to help prevent accidental activation.
