Designed to meet the needs of HDV shooters, the 501HDV features a powerful new feature that takes its inspiration from Manfrotto's top professional head models - a fixed counterbalance spring - which helps ensure both smoother tilt movements and greater equipment safety, even when the tilt locks are inadvertently left off. An easy-access on/off switch allows the counterbalance system to be engaged or disengaged for different filming needs and for quick panning and tilting.
The 501HDV sports an updated design, which has been created for improved ergonomics with locks and knobs that allow for a more solid grip and better control. The large knobs - with all controls on the left side of the head - allow for enhanced ease of use. In addition, the quick release plate (with standard 3/8" thread) has been redesigned to be flush with the casting so that the camera sits flat on top of the video head.
