This is a focus demand operation unit featuring a 4K portable lens for broadcasting. It is used by cameraman on vehicles such as helicopters or automobiles, in the immersive shootings such as concert relays, outdoor or wildlife content. Thanks to the introduction of 4K advanced imaging, more accuracy is required in the focus operation. FUJIFILM adopted a knurled cross-sectional shape from grip side to the front part, allowing for quick and accurate operation in the moving vehicle by a single operator. They extended three rods and applied an arc cross section so that the camera operator with globes can grip it firmly.
