Gitzo’s Center Ball Heads are designed to be an extremely balanced product, that not only guarantee a high max load, but also maximises other key features including minimized drift angle, reduced weight, lowered centre of gravity, increased range of tilt angle, compactness, ergonomics & safety. GH2780QD is the compact Series 2 version, & features a hybrid quick release system which comes with an Arca-style plate but also accepts the traditional Gitzo C-profile plates. The camera/plate can be snapped into the head from above, which is faster & easier than trying to slide it in from the side. By simply removing the adaptor from the head, it will also take Gitzo C-profile plates, especially useful for photographers who already own & use our plates as standard. The new quick release system, compatible with Arca-Swiss plates, is being introduced in many of Gitzo’s heads, Traveler tripod kits, & accessories. With the new system, the camera/plate can be snapped into the head from above, which is faster & easier than trying to slide it in from the side. When a Gitzo plate is used, the quick release system’s secondary safety pin will also engage to prevent camera equipment from falling accidentally from the head, even if the plate locking lever is not fully locked. Gitzo’s D-profile (Arca-Swiss style) plates also feature our new camera screw design; to make it as easy as possible to use, no matter where you are & what tools you have to h&, the screw can be tightened by h&, using a coin or with the supplied allen key. Our hybrid system, featured in some models, fits both Arca-Swiss style plates & traditional Gitzo C-profile plates, making it especially useful for photographers who already own & use our C-profile plates as standard. To accept Gitzo C-profile plates, the adaptor is simply removed from the clamp.
