How to Use the Counter Balance
Tips for Shifting Focus
Be gentle when using the hard stops. Slamming the Focus Shifter against one of the stops hard enough to move the marker board will probably introduce motion in your filming. The stops and marker board system is designed to have some give, in order to reduce movement transmitted to your video. It's best to lightly touch against the stop.
There's not much that can go wrong with the FocusShifter.

Set Focus Marks
Hard Focus Stops
Clip the clips onto the top edge of the marker board, and move them to set the focus stop positions. The FocusShifter should be far enough from the Marker Board that the only part of the clip that contacts the arrow is the wire end of the clip.

Will it fit my lens?
If the diameter of the lens at the focus ring is between 56mm and 98mm, then it will fit. This covers most lens sizes, with the exception of a few large zoom lenses, and some small micro 4/3 lenses. The Follow Focus Shifter is adjustable to fit that size range. The FocusShifter works best with prime lenses. If you have a Zoom lens, there must be at least 10mm of non-rotating space between the Focus and Zoom ring for mounting the marker board.
