This is a very convenient and high quality product. At first I was disappointed because the locking lever touched my DJI Ronin S' roll axis motor when I tried to use the telephoto lens (the camera had to be moved further back). I've found that the sliding portion of the device can be easily removed and rotated so the locking lever faces the front of the camera. In this position I can still reach the locking lever without any problems. Problem solved!
