The WMF2 zoom control brings a brilliant sunlight visible display to the Microforce family allowing the precise setting of focal length as well as user-defined end stops and soft stops. The handle and display are integrated into a robust assembly with multiple mounting options. It links to MDR3, MDR4, or MDR5 either through a hard-wire connection to the MDR Serial or via a 2.4 GHz wireless link. The zoom scale calibration from the HU3 or HU4 is automatically transferred to the WMF2.The HU4 is recommended for highest zoom scale accuracy. The Menu page works with both the dedicated keys and Speed Control knob to make setup quick and intuitive. The Zoom can be configured to work in either Normal mode or in constant speed mode.
