Blackmagic Zoom Demand

The optional zoom and focus demands allow you to use photography lenses for live production! The focus and zoom demands have USB-C connections so they control the lens via the camera’s electronic lens control. 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 so you get very fine lens control, and you can frame and adjust the lens without taking your hands off the tripod handles. The buttons can be customized so you can assign different camera functions to them! Plus, hardware is included for mounting the focus and zoom demands onto tripod handles.
