The Alphatron ProPull 19mm Follow Focus (Rod Support) enables you to control the focus with the best precision. Made from machined aluminum and other high-tech materials, this follow focus is up to the level of the most demanding camera shooter. The ProPull Follow Focus 19mm has a unique design with unique features, as it will be mounted to one single bar of the support system.
This version also features 2 adjustable hard stops to limit the focus draw between 2 desired points, or comes in handy for lenses that do not have hard stops on the focus ring. These points can be placed independently between 3 and 345 degrees from each other. The mounting to one bar only has several advantages. When changing lenses, just release one knob with a simple twist and hinge the follow focus unit aside and you can change lenses unobstructed.
The new lens will have a different diameter, the Follow Focus unit will easily be hinged in place to the new diameter of the lens with a one hand operation. Also when the gear is not at the same distance, the unit can be shifted forward or backwards at the same time.
