Zoom & Focus Controls

About the Zoom & Focus Controls range

Match the controller to the camera or lens interface first. Many camcorders accept a LANC connection, which carries zooming, focus and record commands through one small jack, while broadcast lenses use servo connectors that need a matching demand unit. Look at how the control mounts, usually on a tripod pan handle, and at the rocker's feel: variable-speed rockers let you ease into a slow move. For manual focus on cinema lenses, gear rings add teeth to lenses that lack them. Macro rails move the whole camera in fine steps for close focus work.

The most common mistake is assuming LANC works on every camera. Many mirrorless and cinema cameras have no LANC port, and some camcorders use a different remote protocol, so check the camera's remote terminal before ordering. Broadcast demand units must match the lens servo connector and the camera system. Gear rings need the correct diameter range for the lens and the same 0.8 module pitch as the follow focus. For macro rails, check the load rating and the quick release standard, usually Arca-Swiss, against your camera and lens.
