With the new arms, the camera weight can easily be anything from a pound or two to 50 pounds. That's great,except there are unintended consequences for the sled's length and the monitor's position.
So as an operator, you now have one more thing to worry about — adapting your sled to a much wider range of camera weights than, well, we used to have to worry about. This requires a bit of extra ...
