The disadvantage is that the cameras and associated equipment weigh around 70 to 80 kilograms, and can usually only shoot from a fixed point as they are extremely difficult to maneuver. Such equipment is also very expensive, about NT $ 18 – 20 million, within the reach of only a few domestic production houses. The horizontal mode is relatively simple in comparison.
缺點則是「上下式」的攝影裝置重達 70 ~ 80 公斤，通常只能採「定點拍攝」方式，移動極為不易；而且整套攝影設備的售價極為高昂，約新台幣 1,800 萬～2,000 萬元，國內能負擔得起的製作團隊屈指可數。
