The 509HD systems are the result of an important technical evolution - the perfect synthesis between an innovative bridge architecture and Manfrotto's cutting edge engineering: Bridging Technology - an exclusive Manfrotto patent. Thanks to the 509HD's bridge design the PAN friction control is intuitive and easy to set but also protected against knocks. Movement around the PAN and TILT axes is smoothed by ball-bearing units which remove all unwanted vibration no matter what the operating temperature. Friction control combines with a step counterbalance system (covering the full weight range of video equipment) to allow the 509HD to be fine-tuned with extreme precision for the exact in-shot movements you need. The 509HD's FDS (Fluid Drag System) is variable and directly controls action and resistance on both axes; the ergonomics of the controls have been noticeably improved to make use of the FDS even easier. All of this guarantees ultimate control and excellent video camera support no matter what the situation the shooting style or the equipment setup. The load capacity has also been improved: the 509HD supports kit up to 13kg (28 8lb) at 55mm c.o.g and two 3/8 threads on the top plate allow accessories such as monitors and arms to be fitted straight to the head thus eliminating the need for extra clamps saving set-up time and freeing the video camera's hot shoe for other components. The Manfrotto 509HD is itself a bridge helping the professional videographer reach ever-better results enabling your potential and leading ambitions on towards new challenges. The Manfrotto 509HD systems give you the advantage of total stability and fluidity. An advantage which allows you to go further towards more dynamic eye-opening and creative video.
