I thought i'd test out how well I have things balanced out with the GH4 and Rokinon 7.5mm Fisheye Lens. A few notes - the Rokinon lens is a manual lens with no image stabilization and although parts of this video have been sped up, there is absolutely no image stabilization applied. I'm also holding the gimbal only by it's Top handle. As I reach speeds up to 20mph there is plenty of wind resistance. Considering these factors - I think it faired well.
