The DJI RS 4 Pro Combo is a full set for professional videographers. You can record stable and smooth videos with the gimbal. The included Briefcase Handle is an extra handle for the gimbal that lets you hold the camera close to the ground, for example. When you record on location, you can take the gimbal with you in the included storage case. With the improved quick-release plate of the gimbal, you can quickly switch between horizontal and vertical recording. You can balance the gimbal again after changing the position of the quick-release plate. With the lock function, you lock the stabilized axes. That's great if you're taking it on the go. Once you start recording, you unlock the axes and can place the gimbal in the right positions in seconds. You don't have to stabilize the gimbal again after moving it this way.
