Teradek Pre-Marked Focus Ring - 3’6" minimum focus

The Teradek RT Pre-Marked Focus Ring 3′6″ (11-1449) is a standalone, pre-marked focus ring for lenses with a minimum focus distance of 3 feet 6 inches. It is designed for the Lens Mapping feature of the Teradek RT system on compatible controllers.

Lens Mapping assigns the lens to the corresponding pre-marked ring and enables automatic calibration, so you don’t have to manually re-mark the focus points every time you change lenses. This model uses an imperial scale.
