The 504HD is Manfrotto's latest video fluid head. It is a perfect balance of design and performance. The bridge design improves the head's rigidity and its PAN friction control is fast, simple to fine-tune and protected from knocks. All structural components are made from aluminium, with the PAN axis rotation unit using ball bearings to obtain smooth, totally vibration-free controlled movements that can be directly adjusted using the head's FDS variable friction system. FDS on both the PAN and TILT axes also ensures that the head works perfectly at all temperatures, with all types of equipment and under all loads. Ergonomically improved lever and dial designs combine with the new friction index to give you complete control over the 504HD. The 504HD has been designed to offer a load capacity of up to 7.5kg (16.5lb) making it suitable for a huge range of camera equipment. The CBS counterbalance system has 4 presets for a full range of camera weights (0.2.5kg-5.5lb, 5kg-11lb and 7.5kg-16.5lb). Levelling the head is easy thanks to the 75mm diameter hemisphere and the back-lit bubble level. Two 3/8” threads on the top plate allow accessories (such as monitors and arms) to be directly and securely attached to the head, which helps cut down set-up time, keeps your camera hot shoe free and, saves you from using another clamp. The 504HD is suitable for Manfrotto PRO series video tripods with mid-level or ground spreaders and for carbon fiber single-leg MPRO tripods. Wider, longer platform for your camera and accessories. High rigidity structure delivers maximum response and strength. Ergonomic controls for easy use in all conditions. Easy-link connections for accessories. 4-step counterbalance system ensures a quick set-up with optimal balance. Ball Bearing drag system for precise, smooth movements. Lightweight modern materials for optimum balance of strength and weight.
