Preston Light Ranger 2

300.00
The Light Ranger 2* simultaneously measures distances along 16 horizontally arranged detection zones. The distance measurements allow for high precision manual as well as autofocus operation. The companion video interface unit generates graphic overlays for the focus puller's monitor. In manual focus mode, the subject distances are represented by an array of rectangles, each rectangle representing one of the sixteen detection zones and overlaying the corresponding area of the image where depth is measured. The height of the rectangle above or below the center line represents whether the subject is in front of, behind, or within the lens depth of field (DOF). Subjects within the DOF are identified with green rectangles, otherwise the rectangles are white. In autofocus mode, a red rectangle overlays the monitor image, showing where the distance measurement is taking place. The width of the rectangle is controlled by the north-south axis of the HU3 navigation key and corresponds to the number of detection zones. The horizontal position of the rectangle is controlled by the east-west axis of the navigation key.
