GH2780FQR head brings the quality and performance of the smaller version to a higher level. Its main advantage over the series 1, a part from a higher pay load (that in any case is already more than enough in the series 1 size), is a higher level of control and smoothness, thanks to the larger sphere. This is especially appreciated when some more friction in the movement is required, especially with longer and heavier equipment. Recommended for equipment up to 300 mm lens, it can safely hold larger equipment.
The new center SADL (Spring Assisted Double Lock) is a patent pending system that combines two locking systems in one, that maximizes both locking power and ball smoothness. A high friction metal guarantees a high efficiency lock, the PTFE bushing controlled by a pre-loaded spring maximises smoothness and control.
Safe Grip is a material that gives a safer lock between your camera and the head plate, preventing the camera from moving or slipping. It is used on quick release plates and in applications where the camera equipment is screwed to the support to reduce pivoting and twisting.
When using a ball head, the ability to lock and unlock the panoramic movement independent of front-back or lateral tilt movements is convenient for panoramic photography and when a high level of control is required.
The new leveling system made of three independent leveling bubbles on the quick release plate and one in the ball stem, always guarantee perfectly leveled images. The problem that affects many high quality heads in the market regarding drift angle is absolutely minimised with an outstanding value of 0.03°.
The system consists of two pins, one fixed and one manually operated by means of a button, that prevent camera equipment from suddenly dropping out of the head when the quick release locking knob is released. Extremely useful with heavy equipment, long lenses and spotting scopes.
Gitzo has now developed a new exclusive technology that enables us to produce high quality, completely round hollow spheres, with a ultra thin wall, for an incredible weight reduction. Gitzo Bubble Ball also features a perfected PTFE treatment that further reduces the surface micro roughness for the ultimate shooting experience and accuracy.
In 1996 Gitzo was the first to use Magnesium in camera supports. Magnesium comes in different grades and Gitzoonly uses material of the highest grade quality. It offers significant weight savings being 30% lighter than aluminum.In our magnesium casting every functional bolt and screw works on threads reinforced by high quality steel inserts for a lifetime performance.
PTFE is a special treatment that generates a unique ultra smooth surface and dramatically reduces friction between moving parts. This treatment bonds strongly with metal surfaces and ensures long-lasting performance. PTFE is one of the lowest-friction materials known to science, with the same friction coefficient as melting ice. This treatment is now applied not only to ball heads, but also to plates, video bowls and other sliding parts for smooth, precise and fine movements.
