Hi Julie,
I did get the info. The counterbalance adjusts from 0 lbs to 22 lbs. I have one head holding a Sony PD170 and one holding a Sony EX-1………GREAT! For years, I have been using prosummer heads for my light cameras and always searching for the perfect lightweight head. It does not exist and that statement includes Sachler. The O’Connor heads are heavier but very smoooothe. There is a reason why you see them on so many movie sets.
