I think this new Panasonic Lens will replace my favorite Panasonic 7-14mm F/4 when flying my new GH5 on a Gimbal. The new lens is faster at F/2.8 at it's widest, adds a bit more reach, but most importantly offers filter threads for ND filters. It's not often you'll find a wide angle lens that accepts ND Filters. I don't mind that it's not as wide, as the new Panasonic GH5 camera can operate in 4K Video Mode without adding additional crop (as the GH4 used to). The new Panasonic 8-18mm lens is also dust and splash proof as well.
