Gitzo GH5750QR - Specificaties

The GH5750QR has been completely revised for improved performance and weight reduction. First of all the panoramic lock, developed with a new concept, is now 3 times stronger than before. The ball lock now features a completely new pat-pending system that combines two locking systems in one with the Quick Release System and the leveling spirit bubble.\n\nspring assisted double lock\nThe 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.\n\nsafe grip\nSafe 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.\n\nseparate pan control\nWhen 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.\n\nlevelling bubble\nThe 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°.\n\ndouble quick release safety system\nThe 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.\n\nfriction control\nBy fine tuning the freedom of movement of the head, friction control makes the head slower and more precise or faster and looser. This feature also helps to make using heavy equipment or long lenses safer. On ball and fluid head models without separate friction controls, slowly adjusting the lock knobs gives similar results.\n\nmagnesium\nIn 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.\n\nPTFE – smooth as silk\nPTFE 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.
