During my video making career, I have often wished to have three hands. The hand gripping the pan and tilt handle of the tripod is pretty much fully committed to camera movement and is vastly under used. The other hand however, has too much to do - focus, switch filters, zoom, stop and start, exposure etc etc. As soon as I got this bit of kit I couldn't understand how I used to managed before! I have it fitted to a Sony FX-7 and my video has improved enormously as a result. My advice for anyone using a tripod for video work is just get this thing.
