The DualCam Extension Module is a rather unique gadget from Zhiyun and makes life much easier when you´re shooting without a big production crew.
The DualCam Extension Module lets you attach a second camera to the gimbal with a diffrent focal lenght so you can get two angles at the same time. For instance, if you are a wedding videograopher and to shoot both close-up and wide-angle using two cameras at the same time.
