Not only does this top grip give me better grip and low angle shooting for video, it also allows me to mount more than one on the camera as the threads are different are big. as well as the presence of 3 hot shoe mounts. That way I can have my field monitor, remote trigger and cageless mic on it. It only uses the camera's hot shoe, which is very convenient. You can also attach it to the cage if you want and you have a video rig.
