The 1.7 lb, aluminum-constructed FD-01 Four-Way Head from Sirui has four axes of adjustability. Therefore, the lateral tilt range of the head is -90 to +90°, and its vertical tilt range is -55 to +90°. The head's base rotates a full 360°, but the Arca-type clamp can also rotate 360°, which is applicable for panoramic photography. Apart from the base's 360° rotation, which has its own independent pan lock, each axis has a push-button security lock and a pan lock for the top plate rotation as well. The foldable and portable handle design makes it easy to store when not in use
