Preston Light Ranger 2

The Light Ranger 2 (LR2) focus assist system incorporates an infrared LED/sensor system with 16 distinct measurement zones, allowing the focus puller to visualize the depth of an entire scene without looking away from the monitor.

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 HU3, giving immediate feedback to the focus puller for how to rotate the knob to bring any object into focus. The LR2 also excels in low-light and any other shot with extremely shallow depth-of-field.
