Edelkrone’s FocusOne Pro is a unique take on the traditional follow focus system, giving camera operators a better view of the focus marker.
Unlike other systems, the focus marker on the FocusOne Pro faces the camera operator. The marker is manually adjustable, eliminating the need for a pen. The operator simply rotates the marker point to its desired location.
While the unique location of the marker point is the highlight of the system, there are a few other features worth mentioning. It is compatible with all 15mm rods, however a separate adapter is available for 19mm rods. Reverse gear is included making the system compatible with either Canon or Nikon lenses which have different directions of focus. It can be attached to either side of the lens and is compatible with all DSLR lenses. While the system can be attached directly to lenses with teeth, lens gears are available separately for those without teeth.
This looks like an interesting choice for shooters who want to be able to see their focus marker at all times.
