The Light Ranger 2 is the first and only focus assist system designed for modern high-resolution cameras. The LR2 incorporates an infrared distance measuring system with 16 distinct measurement zones, allowing the focus puller to visualise the depth of an entire scene without looking away from the monitor. In this era of shooting the rehearsal, the LR2 provides focus pullers with innovative tools to accurately judge focus distance in even the toughest shooting scenarios.

Each of the 16 simultaneous distance measurements corresponds to a specific section of the image, and is represented with a green/white rectangle overlayed directly on top of the image at that location. The height of each bar corresponds to its distance in relation to the current knob setting of the HU4, giving immediate feedback to the focus puller for how to rotate the knob to bring any object into focus. White rectangles above the horizontal line on the monitor indicate the subject is further away than the current knob setting of the HU4, while rectangles below that line indicate a subject that is closer than the knob setting. Once the subject is within the depth of field (at the current HU4 knob setting), the rectangle(s) over that subject turns green.

The LR2-W sensor adds a 50° field of view option to the LR2 family. Its wide field of view is perfectly suited for use on Steadicam, crane, and hand-held camera applications.
