The Leofoto LBH-80 Double Ball Head is designed for large lens and camera combinations and features a dual ball system that combines three functions in one head. The inner ball acts as a two-axis head, embedded within the outer ball, which provides leveling and panning. The weight of your camera is balanced by the spring ball head construction. The spring balance is integrated into both balls, allowing for a gimbal-like range of motion without the risk of the lens tipping over. Each ball can be individually tensioned and locked to enable precise control of lens movement. The classic flat design includes an Arca-Swiss receiver clamp that is compatible with a wide range of quick-release plates, mounts, lens foot plates, and other accessories. Ball diameter: outer ball = 82 mm, inner ball = 58 mm.
