The HEDEN YMER-1 VLC11LW Receiver 1+1 Motor with LenSaver Calibration is a wireless focus or iris control system with an optional wired zoom control through LANC. The LenSaver Calibration calibrates a follow focus system by just pressing the calibration button and moving the lens by hand from end stop to end stop, then pressing the button again. The Manual Override makes it possible to take manual control of the lens without jeopardizing calibration. There is a line-of-sight wireless transmission up to 1640'.
In addition, smooth rotary movements of the control knob with adjustable resistance give you a haptic connection with total control of the lenses' movements. There are adjustable limit points for easy focus from A to B, and a precision mode for super-fine control over an adjustable range. One press on the camera run button starts and stops recording from a distance. The mounting points on the transmitter make it easy to attach other devices.
