Genesis Gear universal zoom hand gear is a very useful accessory for filmmakers who want to create footage on a photography lens. The grip has a perforated surface in the shape of gears used in follow focus devices. This product allows you to smoothly operate the focus or focal length of the lens while shooting, which affects the quality of the created footage. It has been created from high-quality rubber to ensure the best possible adjustment to the lens, and it also has a built-in handle to allow the manual setting of the selected value.
