The Blackmagic Design Focus Demand features a USB‑C connection when using with Blackmagic Design compatible Cameras. The Focus Demand allows you to eliminate the need to reach for the lens because you can control the lens directly from the tripod handles, just like a true broadcast lens. Each zoom and focus demand has 2 USB‑C ports, so you can daisy chain them then connect to the camera with a single USB connection. The design has an incredibly precise feel and so you get very fine lens control, and you can frame and adjust the lens without taking your hands off the tripod handles.
