Same as the 490 but equipped with a 410PL quick-release camera plate with a secondary safety catch and two spirit levels for precise leveling on both vertical and horizontal axis. The new 490RC4 replaces the 268 Super Ball Head, and features separate locks on 360° pan and +90°-90° tilt movements, with an additional friction control on the ball movement, giving just the right resistance and smoothness with minimum effort, even when varying weights of equipment.
