Because everything is fixed, neither the angle nor the offset of the lenses can be adjusted, unlike in vertical mode. The advantage, however, is that the weight of the equipment can be kept within 10 – 20 kg, so it is relatively maneuverable and can be used on booms or tracks. This makes it particularly suited to long shots and wide scenes where the lens offset is less critical.
但由於兩個鏡頭都是硬梆梆的實體裝置，鏡頭的視角和軸間距就不能像「上下式」裝置般隨心所欲地調整；好處則是「平行式」裝備可控制在 40 公斤內，相對輕便許多，也能輕鬆安裝在「吊臂」、「推軌」等硬體腳架上，特別適合遠景及大場面的拍攝。
