The Gitzo 2 Way Fluid Head is designed for birders, digiscopers, and wildlife videographers. Weighing less than 21 ounces, it replaces the G2180 as a video head with an 8.8 lb. maximum load, so it is good for 80mm to 95mm spotting scopes with mirrorless cameras or full-sized cameras with lenses up to 200mm. The main differences are that the GHF2W is compatible with the Arca-Swiss plate system and the addition of a fluid cartridge for smoother panning in to go with the tilt cartridge.
