Hi, I recently bought a Steadicam (never had or used one before) but even after balancing it, it keeps spinning whenever I move. I bought it so when I shoot sports games for clients it would be less shaky but it won't balance with that lens (Canon 75-300m). If you could tell me how to balance a heavy lens like that, that would be great. But anyway, so I tried with a lighter lens (Canon 18-55mm) and even though it is kinda balanced, every time I move the steadicam spins around. The camera will just spin to look at me or to the left when I am only moving it forwards to backwards or left to right. How can I fix this? My stedicam is a Pro Gradienter S-40. It came with no instructions so I had to google it.
