Specifically designed for Panasonic HVX200, DVX100B, HMC150, and HPX170 cameras, this is the first and only zoom, focus, and iris control. This powerful combination offers precise control over these three camera functions. Operator may switch between auto and manual control for focus and iris at anytime. Works on all camera supports, stabilizers, tripods, & jibs.

The RockZFI utilizes a pressure-sensitive, side-to-side rocker switch like broadcast zoom controls. This rocker has a greater range of motion for a finer degree of zoom control than the throttle style zoom controls. Adjust iris or focus using smooth and quiet knobs that provide easy operation while you compose your shots. Independent focus/iris knobs allow two people to operate together for critical focus during moving shots or crane moves - imagine the possibilities! The manual/auto switches lock into position, letting you watch the picture, not your hands.
