The follow focus by walimex pro allows an easy but precise tracking of the focus when filming with DSLR cameras. The gear ring can be mounted to any lens and therefore completes the follow focus system. The focus wheel of the system is equipped with a white surface allowing you to mark and reproduce the focus area; this is also facilitated by two stoppers.
The Follow Focus can be mounted to all video rigs with a rod diameter of 15mm on both sides and comes with an accessory adapter for flexible whips and crank levers ideal for use by a camera assistant.
